  • Narrow-phase collision detection algorithms

    - by Marian Ivanov
    There are three phases of collision detection. Broadphase: It loops between all objecs that can interact, false positives are allowed, if it would speed up the loop. Narrowphase: Determines whether they collide, and sometimes, how, no false positives Resolution: Resolves the collision. The question I'm asking is about the narrowphase. There are multiple algorithms, differing in complexity and accuracy. Hitbox intersection: This is an a-posteriori algorithm, that has the lowest complexity, but also isn't too accurate, Color intersection: Hitbox intersection for each pixel, a-posteriori, pixel-perfect, not accuratee in regards to time, higher complexity Separating axis theorem: This is used more often, accurate for triangles, however, a-posteriori, as it can't find the edge, when taking last frame in account, it's more stable Linear raycasting: A-priori algorithm, useful for semi-realistic-looking physics, finds the intersection point, even more accurate than SAT, but with more complexity Spline interpolation: A-priori, even more accurate than linear rays, even more coplexity. There are probably many more that I've forgot about. The question is, in when is it better to use SAT, when rays, when splines, and whether there is anything better.

  • Composing Silverlight Applications With MEF

    - by PeterTweed
    Anyone who has written an application with complexity enough to warrant multiple controls on multiple pages/forms should understand the benefit of composite application development.  That is defining your application architecture that can be separated into separate pieces each with it’s own distinct purpose that can then be “composed” together into the solution. Composition can be useful in any layer of the application, from the presentation layer, the business layer, common services or data access.  Historically people have had different options to achieve composing applications from distinct well known pieces – their own version of dependency injection, containers to aid with composition like Unity, the composite application guidance for WPF and Silverlight and before that the composite application block. Microsoft has been working on another mechanism to aid composition and extension of applications for some time now – the Managed Extensibility Framework or MEF for short.  With Silverlight 4 it is part of the Silverlight environment.  MEF allows a much simplified mechanism for composition and extensibility compared to other mechanisms – which has always been the primary issue for adoption of the earlier mechanisms/frameworks. This post will guide you through the simple use of MEF for the scenario of composition of an application – using exports, imports and composition.  Steps: 1.     Create a new Silverlight 4 application. 2.     Add references to the following assemblies: System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll 3.     Add a new user control called LeftControl. 4.     Replace the LayoutRoot Grid with the following xaml:     <Grid x:Name="LayoutRoot" Background="Beige" Margin="40" >         <Button Content="Left Content" Margin="30"></Button>     </Grid> 5.     Add the following statement to the top of the LeftControl.xaml.cs file using System.ComponentModel.Composition; 6.     Add the following attribute to the LeftControl class     [Export(typeof(LeftControl))]   This attribute tells MEF that the type LeftControl will be exported – i.e. made available for other applications to import and compose into the application. 7.     Add a new user control called RightControl. 8.     Replace the LayoutRoot Grid with the following xaml:     <Grid x:Name="LayoutRoot" Background="Green" Margin="40"  >         <TextBlock Margin="40" Foreground="White" Text="Right Control" FontSize="16" VerticalAlignment="Center" HorizontalAlignment="Center" ></TextBlock>     </Grid> 9.     Add the following statement to the top of the RightControl.xaml.cs file using System.ComponentModel.Composition; 10.   Add the following attribute to the RightControl class     [Export(typeof(RightControl))] 11.   Add the following xaml to the LayoutRoot Grid in MainPage.xaml:         <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">             <Border Name="LeftContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border>             <Border Name="RightContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border>         </StackPanel>   The borders will hold the controls that will be imported and composed via MEF. 12.   Add the following statement to the top of the MainPage.xaml.cs file using System.ComponentModel.Composition; 13.   Add the following properties to the MainPage class:         [Import(typeof(LeftControl))]         public LeftControl LeftUserControl { get; set; }         [Import(typeof(RightControl))]         public RightControl RightUserControl { get; set; }   This defines properties accepting LeftControl and RightControl types.  The attrributes are used to tell MEF the discovered type that should be applied to the property when composition occurs. 14.   Replace the MainPage constructore with the following code:         public MainPage()         {             InitializeComponent();             CompositionInitializer.SatisfyImports(this);             LeftContent.Child = LeftUserControl;             RightContent.Child = RightUserControl;         }   The CompositionInitializer.SatisfyImports(this) function call tells MEF to discover types related to the declared imports for this object (the MainPage object).  At that point, types matching those specified in the import defintions are discovered in the executing assembly location of the application and instantiated and assigned to the matching properties of the current object. 15.   Run the application and you will see the left control and right control types displayed in the MainPage:   Congratulations!  You have used MEF to dynamically compose user controls into a parent control in a composite application model. In the next post we will build on this topic to cover using MEF to compose Silverlight applications dynamically in download on demand scenarios – so .xap packages can be downloaded only when needed, avoiding large initial download for the main application xap.

  • Ubuntu on a virtual machine

    - by Barry Miller
    I've installed Virtual Box and am trying to install Ubuntu 12.04 from a downloaded ISO. Everything is going fine but I come to a choice that says no operating system is dectected on this machine, what would you like to do? 1)Erase disk and install Ubuntu (this will erase any files on the disk) or 2) Something else (choose partition size, multiple partitions, etc). Does the first option mean erase all files on the VIRTUAL DISK--NOT THE COMPUTER? Is it just talking about the virtual machine or if I select this option will it erase my Windows operating system and other files on my hard drive?

  • 3D/perspective Top down shooter bullet issues

    - by Tseng
    I'm developing a top-down shooter with multiple levels (ground for ground units, middle level for buildings, top level for air unity). The problem is the collision. Though I can make the collider box of a bullet be long enough to reach the ground (and collide with it), the real issue is optical. When the bullet is fired from a aircraft and collides with some object on the ground (building, ground unit) it will be optically offset due to the perspective camera, because it looks like the shot "by-passed" the target as seen below Is there any way to make the bullets collide perspectively correct? I'm using Unity3d Engine and it offers only simple colliders (box, sphere, cylinder, mesh and wheel), though I don't think a cone-formed collider would solve this issue. I'd need a (cheap) way to check if it's overlapping a destructible object? I thought of casting a ray from the camera through the bullet and if it hits something destructible, trigger an action, but that's quite punctual and maybe to performance heavy on certain number of bullets

  • Tangent basis calculation problem

    - by Kirill Daybov
    I have the problem with seams with calculating a tangent basis in my application. I'm using a seems to be right algorithm, but it gives wrong result on the seams. What am I doing wrong? Is there a problem with an algorithm, or with the model? The designer says that our models with our normal maps are rendered correctly in Xoliul Shader Plugin in 3Ds Max, so there should be a way to calculate correct tangent basis programmatically. Here's an example of the problem I'm talking about. Steps, I've already taken: - Tried different algorithm (from Gamasutra, I can't post the link because I don't have enough reputation yet). I got wrong, much worse, results; - Tried to average basis vectors for vertexes are used in multiple faces; - Tried to average basis vectors for vertexes that have same world coordinates (this would be obviously wrong solution, but I've tried it anyway).

  • Terminal as desktop background instead of wallper

    - by Janis Erdmanis
    I have come to conclusion that all my needs from nautilus is satisfied with terminal and last file manager. It also dismisses the need for multiple nautilus instances, which makes mess when I forgot how I meant to use different workspaces. The next step for my simplification would be to get rid of any possibility to open nautilus. Also I thought that my interaction with computer is file centred, therefore it makes sense to leave file manager in background of applications. Are there any ways to make terminal as desktop background with which I could interact?

  • Checksum Transformation

    The Checksum Transformation computes a hash value, the checksum, across one or more columns, returning the result in the Checksum output column. The transformation provides functionality similar to the T-SQL CHECKSUM function, but is encapsulated within SQL Server Integration Services, for use within the pipeline without code or a SQL Server connection. As featured in The Microsoft Data Warehouse Toolkit by Joy Mundy and Warren Thornthwaite from the Kimbal Group. Have a look at the book samples especially Sample package for custom SCD handling. All input columns are passed through the transformation unaltered, those selected are used to generate the checksum which is passed out through a single output column, Checksum. This does not restrict the number of columns available downstream from the transformation, as columns will always flow through a transformation. The Checksum output column is in addition to all existing columns within the pipeline buffer. The Checksum Transformation uses an algorithm based on the .Net framework GetHashCode method, it is not consistent with the T-SQL CHECKSUM() or BINARY_CHECKSUM() functions. The transformation does not support the following Integration Services data types, DT_NTEXT, DT_IMAGE and DT_BYTES. ChecksumAlgorithm Property There ChecksumAlgorithm property is defined with an enumeration. It was first added in v1.3.0, when the FrameworkChecksum was added. All previous algorithms are still supported for backward compatibility as ChecksumAlgorithm.Original (0). Original - Orginal checksum function, with known issues around column separators and null columns. This was deprecated in the first SQL Server 2005 RTM release. FrameworkChecksum - The hash function is based on the .NET Framework GetHash method for object types. This is based on the .NET Object.GetHashCode() method, which unfortunately differs between x86 and x64 systems. For that reason we now default to the CRC32 option. CRC32 - Using a standard 32-bit cyclic redundancy check (CRC), this provides a more open implementation. The component is provided as an MSI file, however to complete the installation, you will have to add the transformation to the Visual Studio toolbox by hand. This process has been described in detail in the related FAQ entry for How do I install a task or transform component?, just select Checksum from the SSIS Data Flow Items list in the Choose Toolbox Items window. Downloads The Checksum Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed. Checksum Transformation for SQL Server 2005 Checksum Transformation for SQL Server 2008 Checksum Transformation for SQL Server 2012 Version History SQL Server 2012 Version 3.0.0.27 – SQL Server 2012 release. Includes upgrade support for both 2005 and 2008 packages to 2012. (5 Jun 2010) SQL Server 2008 Version 2.0.0.27 – Fix for CRC-32 algorithm that inadvertently made it sort dependent.

  • Large resolution differences

    - by Robin Betka
    I want to develop a game on multiple devices such as PC, Android or IOS. Want it to be in 1080p, but that means a massive scale down for the smartphones. I know how to do that, just render everything on a 1080p rendertarget and then render it on the screen smaller. But what should I do so that the scalling down doesn't look bad and blury? I can't do it vector based or anything because the sprites simply need a specific size. Should I make the sprites power of two size to get some nice mipmapping? And which other settings can I do? Or should I rather go with a lower resolution but then having a little bit worse look PC version? The performance seems not to be a problem for me, so would be sad not using 1080p because of other problems.

  • How can test users access an unpublished iOS app?

    - by David
    I am considering outsourcing the development of an iOS app to various independent developers. I will have have various testers of the app. We all work for separate companies. Some of these testers will be customers, who I would like feedback from. As there are multiple developers involved I expect there to be a new release on a daily basis. How can this be done? Would each of the testers need to buy some sort of license to avoid having to go through the app approval process? Is there any smooth way to do this so that it will not be a hassle for our friendly customers, who are willing to test our app?

  • Best practice in setting return value (use else or?)

    - by Deckard
    Whenever you want to return a value from a method, but whatever you return depends on some other value, you typically use branching: int calculateSomething() { if (a == b) { return x; } else { return y; } } Another way to write this is: int calculateSomething() { if (a == b) { return x; } return y; } Is there any reason to avoid one or the other? Both allow adding "else if"-clauses without problems. Both typically generate compiler errors if you add anything at the bottom. Note: I couldn't find any duplicates, although multiple questions exist about whether the accompanying curly braces should be on their own line. So let's not get into that.

  • How to play many sounds at once in OpenAL

    - by Krom
    Hello, I'm developing an RTS game and I would like to add sounds to it. My choice has landed on OpenAL. I have plenty of units which from time to time make sounds: fSound.Play(sfx_shoot, location). Sounds often repeat, e.g. when squad of archers shoots arrows, but they are not synced with each other. My questions are: What is the common design pattern to play multiple sounds in OpenAL, when some of them are duplicate? What are the hardware limitations on sounds count and tricks to overcome them?

  • My Rhythmbox plugin can't meet the Ubuntu Software Center "my-app" requirements

    - by allquixotic
    At http://developer.ubuntu.com/publish/my-apps-packages/ the following technical requirements are cited: Technical requirements In order for your application to be distributed in the Software Centre it must: Be in one, self-contained directory when installed Be able to be installed into the /opt/ directory (*) Be executable by all users from the /opt/ directory (**) Write all configuration settings to ~/.config/ (This can be one file or a directory containing multiple configuration files) A Rhythmbox plugin cannot satisfy any of these requirements. Rhythmbox has compiled-in locations where it looks for installed plugins. So, is there no way for me to publish my app in Ubuntu Software Center? Would it have to go into Universe repository (which would require tremendously more work and political maneuvering to get it accepted)? I already have all the Debian package infrastructure built for it, so I have made a PPA for it.

  • What are the preferred documentation tools for the major programming languages?

    - by Dave Peck
    I'm interested in compiling a list of major programming languages and their preferred documentation toolsets. To scope this a bit: The exact structure of the answer may vary from language to language, but there appear to be two aspects common to all languages: (1) in-code syntax for documentation, and (2) documentation generators that make use of said syntax. There are also cases where generators are used independent of code. For example, tutorial-style documentation is common in the Python world and is often disconnected from underlying code. Many languages have multiple commonly-used documentation strategies and tool chains, and I'd love to capture this. Finally, there are cross-language tools like Doxygen that also have some traction and would be worth noting here. Here are some obvious target languages to start with: Python, Ruby, Java, C#, PHP, Objective-C, C/C++, Haskell, Erlang, Scala, Clojure If this question catches on, I'll try and keep this section updated with the most recent list. Thanks!

  • How To Create a Personal VM Server

    - by Danish
    I have a personal Ubuntu server at home for my various personal development needs. I often spend time to configure it for various purposes e.g. for serving a blog or my mercurial repositories etc. However, I am getting very interested in pre-packaged linux appliances available e.g. TurnKey linux etc. It takes no effort to get an appliance up and running! I was wondering if I could make my home server into VM server, where I can run multiple VMs for various needs. The server does not have a screen, hence I would like to be able to manage my VMs from the web or console I guess in short, I am asking if its possible to have my own personal, light weight Amazon EC2. If yes, how can I set it up? Is there an Ubuntu derived distro available for this? OR can I install a couple of packages and get this running?

  • Setting Up and Managing Local IPS Repositories

    - by user12244672
    My colleague, Albert White, has published a useful article detailing how to set up local IPS repositories for use within an enterprise: How to Create Multiple Internal Repositories for Oracle Solaris 11 This is useful as most servers will not be directly connected to the Internet and most customers will want to control which Oracle Solaris SRUs (Support Repository Updates) are "qualified" for deployment within their organization.  Setting up and managing Internal IPS (Image Packaging System) Repositories is the way to do this. The concept can naturally be extended and adapted.  For example, Albert talks about a "Development" Repo containing the latest Oracle Solaris 11 deliverables.  When qualifying a software level for deployment across the enterprise, a copy of a specific level could be taken, e.g. "GoldenImage2012Q3" or "SRU8.5", and once it passes testing, be used to deploy across the enterprise. Best Wishes, Gerry.

  • SQL SERVER – Retrieving Random Rows from Table Using NEWID()

    - by pinaldave
    I have previously written about how to get random rows from SQL Server. SQL SERVER – Generate A Single Random Number for Range of Rows of Any Table – Very interesting Question from Reader SQL SERVER – Random Number Generator Script – SQL Query However, I have not blogged about following trick before. Let me share the trick here as well. You can generate random scripts using following methods as well. USE AdventureWorks2012 GO -- Method 1 SELECT TOP 100 * FROM Sales.SalesOrderDetail ORDER BY NEWID() GO -- Method 2 SELECT TOP 100 * FROM Sales.SalesOrderDetail ORDER BY CHECKSUM(NEWID()) GO You will notice that using NEWID() in the ORDER BY will return random rows in the result set. How many of you knew this trick? You can run above script multiple times and it will give random rows every single time.

  • Best way to address this Magento issue

    - by robgt
    I am in need of some advice/pointers on how best to attack a problem I am faced with in Magento 1.4.0.1. Here is the scenario: Consider a product catalog of multiple thousands of products in which there are many and various retail markup percentages. There is a need to sell some of those products to other retailers, and I need a way to easily categorise them into percentrage markup groups, so that the other traders can easily purchase items from us without needing to call and confirm pricing. All products prices are added to the magento database including VAT - so the actual retail value is the starting point. I think this needs to be done by adding an attribute on the products that determines the maximum discount level that can be applied to any given product. Obviously, this would entail a massive amount of work to update every product. Is there a way to achieve what we need that I don't yet know about (within Magento)? Can single attribute values be mass-populated somehow, without affecting other attributes such as name/description/etc?

  • XBRL - Moving from Production to Consumption

    - by jmorourke
    Here's an update on what’s new with XBRL and how it can actually benefit your organization versus adding extra time and costs to financial reporting.  On February 29th (leap day) of 2012 I attended the XBRL and Financial Analysis Technology Conference at Baruch College in NYC.  The event, which attracted over 300 XBRL gurus and fans was presented by XBRL US, The New York Society of Security Analysts’ Improved Corporate Reporting Committee, and Baruch College’s Robert Zicklin Center for Corporate Integrity.  The event featured keynotes from the U.S. Securities and Exchange Commission (SEC), and the CFA Institute as well as panels covering alternative research tools and data, corporate reporting to stakeholders and a demonstration of XBRL analysis tools.  The program culminated in a presentation of the finalists and the winner of the $20,000 XBRL Challenge.    Some of the key points made in the sessions included: The focus of XBRL tools is moving from production to consumption. As of February 2012, over 9000 companies are reporting in XBRL, with over 10 million facts filed to date XBRL taxonomy extensions have dropped from 27% to 11% making comparisons easier The SEC reports that XBRL makes it easier to analyze disclosures, focus on accounting issues XBRL is helping standards-setters like the FASB speed their analysis of impacts of proposed accounting rule changes Companies like Thomson Reuters report that XBRL is helping speed the delivery of data to clients The most interesting part of the program though, was the session highlighting the 5 finalists in the XBRL Challenge competition and the winning solution.  The XBRL Challenge was launched in 2011 as a means of spurring the development of more end-user tools to help with the consumption of XBRL-based financial information.       Over an 8-month process handled by 5 judges, there were 84 registrants, 15 completed submissions, 5 finalists and one winner of the challenge.  All of the solutions are open-sourced tools and most of them focus on consuming XBRL-based data.  The 5 finalists included: Advanced XBRL Processing from Oxide solutions – XBRL viewer for taxonomies, filings and company data with peer comparison capabilities. Arrelle – API for XBRL processes, supports SEC Validations, RSS Feeds to access filings etc. Calcbench – XBRL data analysis tool that can be embedded in other web applications.  This tool can combine XBRL filings with real-time market data. XBRL to XL – allows the importing of XBRL data into Microsoft Excel for analysis, comparisons.  Users start on the web and populate Excel with XBRL data. XBurble – allows users to search and view XBRL filings, export to Excel, merge for comparison, and includes a workflow interface. The winner of the $20,000 XBRL Challenge prize was CalcBench.  More information about the XBRL Challenge and the finalists can be found at www.XBRLUS.org/challenge XBRL for Sustainability Reporting – other recent news on the XBRL front was the announcement by the Global Reporting Initiative (GRI) of an XBRL taxonomy for Sustainability Reporting.  This taxonomy was co-developed by the GRI and Deloitte and is designed to make the consumption of data found in Sustainability Reports much easier.  Although there is no government mandate to file Sustainability Reports in XBRL format, organizations that do use the GRI guidelines for Sustainability Reporting are encouraged to tag and submit their data voluntarily to the GRI – who will populate a database with Sustainability Reporting data and make this available to the public.  For more information about this initiative, you can go to the GRI web site:  www.globalreporting.org. So how does all of this benefit corporate filers and investors?  Since its introduction, the consensus in the market is that XBRL has mainly benefited the regulators and investment analysts who need to consume and analyze large volumes of financial data.  But with the emergence of more end-user tools for consuming and analyzing XBRL-based data, and the ability to perform quick comparisons of one company versus its peers and competitors in an industry group, will soon accelerate the benefits to corporate finance staff, as well as individual investors.  This could apply to financial results tagged in XBRL, as well as non-financial information such as Sustainability Reporting – which over the long-term will likely be integrated with financial reporting.   And as multiple regulators and agencies in a country adopt the XBRL standard for corporate filings, more benefits will accrue as companies will be able to leverage one set of XBRL-based financial data for multiple regulatory filings.     For more information about the latest developments in XBRL, check out the XBRL US or XBRL International web sites:  www.xbrl.org, www.xbrlus.org.
