• Have you used nDepend?

  - by Nick Harrison

  Have you Used NDepend? I have often wanted to use it, but never spent the money on it.   I have developed many tools that try to do pieces of what NDepend does, but never with as much success as they reach. Put simply, it is a tool that will allow you to udnerstand and monitor the architecture of your software, and it does it in some pretty amazing ways. One of the most impressive features is something that they call Code Query Language.   It allows you to write queries very similar to SQL to track the performance of various software metrics and use this to identify areas that are out of compliance with your standards and architecture. For instance, once you have analyzed your project, you can write queries such as : SELECT METHODS WHERE IsPublic AND CouldBePrivate  You can also set up such queries to provide warnings if there are records returned.    You can incorporae this into your daily build and compare build against build. There are over 82 metrics included to allow you to view your code in a variety of angles. I have often advocated for a "Code Inventory" database to track the state of software and the ROI on software investments.    This tool alone will take you about 90% of the way there. If you are not using it yet,  I strongly recommend that you do!

• Do you store mysql exports in your version control tool for reverting to in event of error?

  - by Rob

  We run an internal web server with in-house software to run a manufacturing line. When new product features are to be added, either or both of the following occur: changes to the in-house server software may be required to support these - these are for significant changes in functionality, being code drive. changes to the MySQL database for new entries for the part numbers, these are for smaller changes, configurations, changes to already existing values and parameters -- such changes don't require code changes. Ideally we'd want our changes to be here rather than in item 1. Item 1 is version controlled in Subversion, so previous revisions can be referred to for rolling back to in the event of problems introduced in the latest revision. But what about changes to the MySQL database? We have quality processes to ensure that such changes are error-free but there is always a chance that errors can pass through, e.g. mistake in data entry or faults with the code that uses the MySQL corrupting the database etc. We have a automated backup every 6 hours but what if we want more manual defined checkpoints in between these intervals, we could use the same backup system but I wondered if folks here used other methods to store previous states of databases, e.g. exporting the database as a plain text SQL dump -- at least with this method it would be possible to see diffs e.g. in Beyond Compare for trouble shooting. Thoughts?

• Code structure for multiple applications with a common core

  - by Azrael Seraphin

  I want to create two applications that will have a lot of common functionality. Basically, one system is a more advanced version of the other system. Let's call them Simple and Advanced. The Advanced system will add to, extend, alter and sometimes replace the functionality of the Simple system. For instance, the Advanced system will add new classes, add properties and methods to existing Simple classes, change the behavior of classes, etc. Initially I was thinking that the Advanced classes simply inherited from the Simple classes but I can see the functionality diverging quite significantly as development progresses, even while maintaining a core base functionality. For instance, the Simple system might have a Project class with a Sponsor property whereas the Advanced system has a list of Project.Sponsors. It seems poor practice to inherit from a class and then hide, alter or throw away significant parts of its features. An alternative is just to run two separate code bases and copy the common code between them but that seems inefficient, archaic and fraught with peril. Surely we have moved beyond the days of "copy-and-paste inheritance". Another way to structure it would be to use partial classes and have three projects: Core which has the common functionality, Simple which extends the Core partial classes for the simple system, and Advanced which also extends the Core partial classes for the advanced system. Plus having three test projects as well for each system. This seems like a cleaner approach. What would be the best way to structure the solution/projects/code to create two versions of a similar system? Let's say I later want to create a third system called Extreme, largely based on the Advanced system. Do I then create an AdvancedCore project which both Advanced and Extreme extend using partial classes? Is there a better way to do this? If it matters, this is likely to be a C#/MVC system but I'd be happy to do this in any language/framework that is suitable.

• Low graphic mode after switching to fglrx drivers

  - by MrKenkadze27

  I have another problem on my laptop after trying to fix another issue. So, because of this issue, I wanted to switch to fglrx to fix it and after restart, I got this screen: I went back to terminal and I got rid of this problem by "purge"-ing the fglrx driver and removing it, going back to problem number one. I tried lot of methods to fix this such as this ones but they ether switched back to open-source drivers or didn't helped at all. So would anyone like to help? maybe give some commends to try? My Laptop has 2 GPU, AMD Radeon HD 7650M and Intel(R) HD Graphics 4000. AMD is running always making my laptop too hot. Here's one of the Xorg.5.log file paste, I am sure it will be useful finding my problem. Thanks! Please make answer easy to understand as I am not an expert, this problem is keeping me from being one. Also the AMD driver which can be downloaded from their site doesn't install, it says non compatible graphics card but Ubuntu Software Updater sure installs it.

• Generic Repositories with DI & Data Intensive Controllers

  - by James

  Usually, I consider a large number of parameters as an alarm bell that there may be a design problem somewhere. I am using a Generic Repository for an ASP.NET application and have a Controller with a growing number of parameters. public class GenericRepository<T> : IRepository<T> where T : class { protected DbContext Context { get; set; } protected DbSet<T> DbSet { get; set; } public GenericRepository(DbContext context) { Context = context; DbSet = context.Set<T>(); } ...//methods excluded to keep the question readable } I am using a DI container to pass in the DbContext to the generic repository. So far, this has met my needs and there are no other concrete implmentations of IRepository<T>. However, I had to create a dashboard which uses data from many Entities. There was also a form containing a couple of dropdown lists. Now using the generic repository this makes the parameter requirments grow quickly. The Controller will end up being something like public HomeController(IRepository<EntityOne> entityOneRepository, IRepository<EntityTwo> entityTwoRepository, IRepository<EntityThree> entityThreeRepository, IRepository<EntityFour> entityFourRepository, ILogError logError, ICurrentUser currentUser) { } It has about 6 IRepositories plus a few others to include the required data and the dropdown list options. In my mind this is too many parameters. From a performance point of view, there is only 1 DBContext per request and the DI container will serve the same DbContext to all of the Repositories. From a code standards/readability point of view it's ugly. Is there a better way to handle this situation? Its a real world project with real world time constraints so I will not dwell on it too long, but from a learning perspective it would be good to see how such situations are handled by others.

• F# Simple Twitter Update

  - by mroberts

  A short while ago I posted some code for a C# twitter update.  I decided to move the same functionality / logic to F#.  Here is what I came up with. 1: namespace Server.Actions 2:   3: open System 4: open System.IO 5: open System.Net 6: open System.Text 7:   8: type public TwitterUpdate() = 9: 10: //member variables 11: [<DefaultValue>] val mutable _body : string 12: [<DefaultValue>] val mutable _userName : string 13: [<DefaultValue>] val mutable _password : string 14:   15: //Properties 16: member this.Body with get() = this._body and set(value) = this._body <- value 17: member this.UserName with get() = this._userName and set(value) = this._userName <- value 18: member this.Password with get() = this._password and set(value) = this._password <- value 19:   20: //Methods 21: member this.Execute() = 22: let login = String.Format("{0}:{1}", this._userName, this._password) 23: let creds = Convert.ToBase64String(Encoding.ASCII.GetBytes(login)) 24: let tweet = Encoding.ASCII.GetBytes(String.Format("status={0}", this._body)) 25: let request = WebRequest.Create("http://twitter.com/statuses/update.xml") :?> HttpWebRequest 26: 27: request.Method <- "POST" 28: request.ServicePoint.Expect100Continue <- false 29: request.Headers.Add("Authorization", String.Format("Basic {0}", creds)) 30: request.ContentType <- "application/x-www-form-urlencoded" 31: request.ContentLength <- int64 tweet.Length 32: 33: let reqStream = request.GetRequestStream() 34: reqStream.Write(tweet, 0, tweet.Length) 35: reqStream.Close() 36:   37: let response = request.GetResponse() :?> HttpWebResponse 38:   39: match response.StatusCode with 40: | HttpStatusCode.OK -> true 41: | _ -> false   While the above seems to work, it feels to me like it is not taking advantage of some functional concepts.  Love to get some feedback as to how to make the above more “functional” in nature.  For example, I don’t like the mutable properties.

• AsyncBridge? Async on .NET 4.0 using VS11

  - by Alex.Davies

  I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

• How would you TDD the functionality of getting the corresponding process of a running windows service?

  - by Matt Spinelli

  Purpose Over the last year or more I've been learning unit testing via books I've read recently like The Art of Unit Testing, Working Effectively with Legacy Code, and others. I've also been using unit tests, mocking frameworks, and the like, periodically at work and definitely see the value. However, I'm still having a hard time wrapping my mind around TDD (as opposed to TAD) when the situation calls for code that is gong to mostly use external API calls. Problem to solve Get the process associated with a windows service using the service name. example: Function GetProcess(ByVal serviceName As String) As Process Rules Show each major iteration in production & test code using TDD No need to see any other code or configuration that is required to get things to run. Just curious about the interfaces, concrete classes, and test methods. C# or VB.NET Must use the .Net framework regarding services/processes (i.e. System.Diagnostics.Process) Test Frameworks: Nunit or MSTest Isolation Frameworks: Moq, Rhino Mock, or Microsoft Moles Must write true unit tests (no integration tests) Additional notes As far as I can tell there are two approaches design wise. Use an Inversion of Control approach along with using the Adapter and/or Facade patterns to wrap the underlying .net framework objects dealing with processes and services. Keep the .net framework code in the class containing the Get Process method and use code detouring (interception) via Microsoft Moles to isolate the hard dependencies from the method under test.

• Mock the window.setTimeout in a Jasmine test to avoid waiting

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2014/08/21/mock-the-window.settimeout-in-a-jasmine-test-to-avoid-waiting.aspxJasmine has a clock mocking feature, but I was unable to make it work in a function that I’m calling and want to test. The example only shows using clock for a setTimeout in the spec tests and I couldn’t find a good example. Here is my current and slightly limited approach.   If we have a method we want to test: var test = function(){ var self = this; self.timeoutWasCalled = false; self.testWithTimeout = function(){ window.setTimeout(function(){ self.timeoutWasCalled = true; }, 6000); }; }; Here’s my testing code: var realWindowSetTimeout = window.setTimeout; describe('test a method that uses setTimeout', function(){ var testObject; beforeEach(function () { // force setTimeout to be called right away, no matter what time they specify jasmine.getGlobal().setTimeout = function (funcToCall, millis) { funcToCall(); }; testObject = new test(); }); afterEach(function() { jasmine.getGlobal().setTimeout = realWindowSetTimeout; }); it('should call the method right away', function(){ testObject.testWithTimeout(); expect(testObject.timeoutWasCalled).toBeTruthy(); }); }); I got a good pointer from Andreas in this StackOverflow question. This would also work for window.setInterval. Other possible approaches: create a wrapper module of setTimeout and setInterval methods that can be mocked. This can be mocked with RequireJS or passed into the constructor. pass the window.setTimeout function into the method (this could get messy)

• MonoGame not all letters being drawn with DrawString

  - by Lex Webb

  I'm currently making a dynamic user interface for my game and are setting up having text on my buttons. I'm having an odd issue where, when i use a specific piece of code to determine the text position, it will not render all of the text passed to DrawString. Even weirder, is if i insert another DrawString after this, drawing more text at a different place, different parts of the text will be drawn. The code for drawing my button with the text attached is: public override void Draw(SpriteBatch sb, GameTime gt) { sb.Draw(currentImage, GetRelativeRectangle(), Color.White); sb.DrawString(font, text, new Vector2(this.GetRelativeDrawOffset().X + this.Width / 2 - font.MeasureString(text).X / 2, this.GetRelativeDrawOffset().Y + this.Height / 2 - font.MeasureString(text).Y / 2), textColor); } The methods in the creation of the Vector2 simply get the draw position of the button. I'm then doing some calculation to center the text. This produces this when the text is set to 'Test': And when i enter this piece of code below the first DrawString: sb.DrawString(font, "test", new Vector2(500, 50), Color.Pink); I should mention that that grey square is being drawn in the same spritebatch, before the button and the text. Any ideas as to what could be causing this? I have a feeling it may be due to draw order, but i have no idea how to control that.

• Inspiring the method of teaching. Example- C++ :)

  - by Ashwin

  A year ago I graduated with a degree in Computer Science and Engineering. Considering C++ as the first choice of programming language I have been in the process of learning C++ in many ways. At first - five years back - I had many conceptions, most of which were so abstract to me. It started when I knew almost everything about Structs in C and nothing about Classes in C++. I went through a great time experimenting them all and learning a lot. I had a hard time evaluating Procedural programming vs Object-Oriented Programming. Deciding when to choose Procedural or Object-Oriented Programming took a great deal of patience for me. I knew that I cannot underestimate any of these Programming styles... Though Procedural programming is often a better choice than simple sequential unstructured programming, when solving problems with procedural programming, we usually divide one problem into several steps in order regarded as functions. Then we call these functions one by one to get the result of the problem. When solving problems with Object Oriented Priciples we divide one problem into several classes and form the interaction between them. Evaluating these two at the beginning (as a learner) required a lot of inspiration and thoughts. Instructing to think step by step. Relative concepts to understand deeply. Intensive interests to contrast both solving in both POP and OOP. If you were ever a mentor: What ideas/methods would you teach to students in which it will Inspire them to learn a programming language (in general, computer sciences)?

• Isometric Camera trouble - can't rotate or move correctly

  - by Deukalion

  I'm trying to create a 3D editor, but I've been having some trouble with the Camera and understanding each component. I've created 2 camera that works OK, but now I'm trying to implement an Isometric Camera in XNA without success on the rotation and movement of the camera. All I get working is Zoom. (Cube with x=3f, y=3f, z=1f in center) And this is the constructor for my IsometricCamera (inherits from ICamera, with methods for Rotation, Movement and Zoom, and Properties for World/View/Projection matrices) public IsometricCamera3D(GraphicsDevice device, float startClip = -1000f, float endClip = 1000f) { matrix_projection = Matrix.CreateOrthographic(device.Viewport.Width, device.Viewport.Height, startClip, endClip); rotation = Vector3.Zero; matrix_view = Matrix.CreateScale(zoom) * Matrix.CreateRotationY(MathHelper.ToRadians(45 + 180)) * Matrix.CreateRotationX(MathHelper.ToRadians(30)) * Matrix.CreateRotationZ(MathHelper.ToRadians(120)) * Matrix.CreateTranslation(rotation.X, rotation.Y, rotation.Z); } Problem is when I rotate it, all that happens is that the Cube gets more or less shiny and nothing happens. What is wrong and how should I create my View matrix to move it / rotate it correctly? Rotate, Move and Zoom looks like: MethodName(Vector3 rotation/movement), Zoom(float value); and just increases the value, then calls an update to recreate the View Matrix according to the code in the constructor. Currently, in my editor I use MiddleButton + Mouse Movement to rotate the camera, but it's not working as the other camera. But in my default camera I use World Matrix to move, but I guess that's not the best way to go which is why I'm trying this.

• SEO + international sites? country.domain.com or domain.country?

  - by Pure.Krome

  Hi folks, is it better to have seperate country specific domains (which costs more money) or subdomains which define the country, for better SEO? eg. stackoverflow.com stackoverflow.com.au stackoverflow.co.uk vs stackoverflow.com au.stackoverflow.com uk.stackoverflow.com Assumption: int the search engine web master tools, each subdomain are associated to a country. eg. au.stackoverflow.com is associated to the country Australia. cheers! Update I understand that both methods do work, especially when i utilize the assumption, listed above. The question is about: Which method is better? Is there such a small SEO difference between them? Is the first method way way way better than the second with getting better SEO results? Update #2 A number of folks have suggested that the following is a good/better approach: stackoverflow.com/ stackoverflow.com/au stackoverflow.com/uk By adding a country specific iso code to the end of the url/the first folder of the domain can be recognised as the country. But a number of SEO mates have suggested that this is a valuable waste of folder level space. Er.. how can i explain. Ok, it's been suggested by some SEO experts that if the number of levels or folders in the domain exceeds 5 then the page drops dramatically in importance. Basically, you don't want to make it deep. As such, adding the country as the first level can be considered a waste, especially when it can be handled by the domain OR subdomain - hence the question :) So, any more thoughts on this? (Maybe SO is the wrong place to ask this question?)

• Intellectual-Property Question

  - by Roger J. J.

  Like almost everyone here, I have a handfull of scripts and software that I have developed and am enthused about. I will be looking for my first job as a software designer / coder. It seems natural that I will be eager to please my employer and use scripts or similar methods that I have developed and worked for me in the past to please my employer. It seems certain that many things that I code will look very similar to things I have coded in the past. I don't understand how to document and articulate to an employer that this code base was mine before I got here and this will continue to be mine when I leave. Surely, this is a common issue, but none of the various searches I've done on the net have produced an answer to this question. How is this situation commonly dealt with in the industry? I feel like there should be a digital version of sending myself a 'certified letter' with my code/software/scripts contained. I'm not trying to protect my code from others using it; I am trying to protect my right to continue using my code base that I have developed prior to to gaining employment with an employer.

• An alternative to multiple inheritance when creating an abstraction layer?

  - by sebf

  In my project I am creating an abstraction layer for some APIs. The purpose of the layer is to make multi-platform easier, and also to simplify the APIs to the feature set that I need while also providing some functionality, the implementation of which will be unique to each platform. At the moment, I have implemented it by defining and abstract class, which has methods which creates objects that implement interfaces. The abstract class and these interfaces define the capabilities of my abstraction layer. The implementation of these in my layer should of course be arbitrary from the POV view of my application, but I have done it, for my first API, by creating chains of subclasses which add more specific functionality as the features of the APIs they expose become less generic. An example would probably demonstrate this better: //The interface as seen by the application interface IGenericResource { byte[] GetSomeData(); } interface ISpecificResourceOne : IGenericResource { int SomePropertyOfResourceOne {get;} } interface ISpecificResourceTwo : IGenericResource { string SomePropertyOfResourceTwo {get;} } public abstract class MyLayer { ISpecificResourceOne CreateResourceOne(); ISpecificResourceTwo CreateResourceTwo(); void UseResourceOne(ISpecificResourceOne one); void UseResourceTwo(ISpecificResourceTwo two); } //The layer as created in my library public class LowLevelResource : IGenericResource { byte[] GetSomeData() {} } public class ResourceOne : LowLevelResource, ISpecificResourceOne { int SomePropertyOfResourceOne {get{}} } public class ResourceTwo : ResourceOne, ISpecificResourceTwo { string SomePropertyOfResourceTwo {get {}} } public partial class Implementation : MyLayer { override UseResourceOne(ISpecificResourceOne one) { DoStuff((ResourceOne)one); } } As can be seen, I am essentially trying to have two inheritance chains on the same object, but of course I can't do this so I simulate the second version with interfaces. The thing is though, I don't like using interfaces for this; it seems wrong, in my mind an interface defines a contract, any class that implements that interface should be able to be used where that interface is used but here that is clearly not the case because the interfaces are being used to allow an object from the layer to masquerade as something else, without the application needing to have access to its definition. What technique would allow me to define a comprehensive, intuitive collection of objects for an abstraction layer, while their implementation remains independent? (Language is C#)

• Design for object with optional and modifiable attributtes?

  - by Ikuzen

  I've been using the Builder pattern to create objects with a large number of attributes, where most of them are optional. But up until now, I've defined them as final, as recommended by Joshua Block and other authors, and haven't needed to change their values. I am wondering what should I do though if I need a class with a substantial number of optional but non-final (mutable) attributes? My Builder pattern code looks like this: public class Example { //All possible parameters (optional or not) private final int param1; private final int param2; //Builder class public static class Builder { private final int param1; //Required parameters private int param2 = 0; //Optional parameters - initialized to default //Builder constructor public Builder (int param1) { this.param1 = param1; } //Setter-like methods for optional parameters public Builder param2(int value) { param2 = value; return this; } //build() method public Example build() { return new Example(this); } } //Private constructor private Example(Builder builder) { param1 = builder.param1; param2 = builder.param2; } } Can I just remove the final keyword from the declaration to be able to access the attributes externally (through normal setters, for example)? Or is there a creational pattern that allows optional but non-final attributes that would be better suited in this case?

• Refactoring and Open / Closed principle

  - by Giorgio

  I have recently being reading a web site about clean code development (I do not put a link here because it is not in English). One of the principles advertised by this site is the Open Closed Principle: each software component should be open for extension and closed for modification. E.g., when we have implemented and tested a class, we should only modify it to fix bugs or to add new functionality (e.g. new methods that do not influence the existing ones). The existing functionality and implementation should not be changed. I normally apply this principle by defining an interface I and a corresponding implementation class A. When class A has become stable (implemented and tested), I normally do not modify it too much (possibly, not at all), i.e. If new requirements arrive (e.g. performance, or a totally new implementation of the interface) that require big changes to the code, I write a new implementation B, and keep using A as long as B is not mature. When B is mature, all that is needed is to change how I is instantiated. If the new requirements suggest a change to the interface as well, I define a new interface I' and a new implementation A'. So I, A are frozen and remain the implementation for the production system as long as I' and A' are not stable enough to replace them. So, in view of these observation, I was a bit surprised that the web page then suggested the use of complex refactorings, "... because it is not possible to write code directly in its final form." Isn't there a contradiction / conflict between enforcing the Open / Closed Principle and suggesting the use of complex refactorings as a best practice? Or the idea here is that one can use complex refactorings during the development of a class A, but when that class has been tested successfully it should be frozen?

• Augmenting functionality of subclasses without code duplication in C++

  - by Rob W

  I have to add common functionality to some classes that share the same superclass, preferably without bloating the superclass. The simplified inheritance chain looks like this: Element -> HTMLElement -> HTMLAnchorElement Element -> SVGElement -> SVGAlement The default doSomething() method on Element is no-op by default, but there are some subclasses that need an actual implementation that requires some extra overridden methods and instance members. I cannot put a full implementation of doSomething() in Element because 1) it is only relevant for some of the subclasses, 2) its implementation has a performance impact and 3) it depends on a method that could be overridden by a class in the inheritance chain between the superclass and a subclass, e.g. SVGElement in my example. Especially because of the third point, I wanted to solve the problem using a template class, as follows (it is a kind of decorator for classes): struct Element { virtual void doSomething() {} }; // T should be an instance of Element template<class T> struct AugmentedElement : public T { // doSomething is expensive and uses T virtual void doSomething() override {} // Used by doSomething virtual bool shouldDoSomething() = 0; }; class SVGElement : public Element { /* ... */ }; class SVGAElement : public AugmentedElement<SVGElement> { // some non-trivial check bool shouldDoSomething() { /* ... */ return true; } }; // Similarly for HTMLAElement and others I looked around (in the existing (huge) codebase and on the internet), but didn't find any similar code snippets, let alone an evaluation of the effectiveness and pitfalls of this approach. Is my design the right way to go, or is there a better way to add common functionality to some subclasses of a given superclass?

• Per-vertex animation with VBOs: Stream each frame or use index offset per frame?

  - by charstar

  Scenario Meshes are animated using either skeletons (skinned animation) or some form of morph targets (i.e. per-vertex key frames). However, in either case, the animations are known in full at load-time, that is, there is no physics, IK solving, or any other form of in-game pose solving. The number of character actions (animations) will be limited but rich (hand-animated). There may be multiple characters using a each mesh and its animations simultaneously in-game (they will be at different poses/keyframes at the same time). Assume color and texture coordinate buffers are static. Goal To leverage the richness of well vetted animation tools such as Blender to do the heavy lifting for a small but rich set of animations. I am aware of additive pose blending like that from Naughty Dog and similar techniques but I would prefer to expend a little RAM/VRAM to avoid implementing a thesis-ready pose solver. I would also like to avoid implementing a key-frame + interpolation curve solver (reinventing Blender vertex groups and IPOs). Current Considerations Much like a non-shader-powered pose solver, create a VBO for each character and copy vertex and normal data to each VBO on each frame (VBO in STREAMING). Create one VBO for each animation where each frame (interleaved vertex and normal data) is concatenated onto the VBO. Then each character simply has a buffer pointer offset based on its current animation frame (e.g. pointer offset = (numVertices+numNormals)*frameNumber). (VBO in STATIC) Known Trade-Offs In 1 above: Each VBO would be small but there would be many VBOs and therefore lots of buffer binding and vertex copying each frame. Both client and pipeline intensive. In 2 above: There would be few VBOs therefore insignificant buffer binding and no vertex data getting jammed down the pipe each frame, but each VBO would be quite large. Are there any pitfalls to number 2 (aside from finite memory)? Are there other methods that I am missing?
