  • Bounding Boxes for Circle and Arcs in 3D

    - by David Rutten
    Given curves of type Circle and Circular-Arc in 3D space, what is a good way to compute accurate bounding boxes (world axis aligned)? Edit: found solution for circles, still need help with Arcs. C# snippet for solving BoundingBoxes for Circles: public static BoundingBox CircleBBox(Circle circle) { Point3d O = circle.Center; Vector3d N = circle.Normal; double ax = Angle(N, new Vector3d(1,0,0)); double ay = Angle(N, new Vector3d(0,1,0)); double az = Angle(N, new Vector3d(0,0,1)); Vector3d R = new Vector3d(Math.Sin(ax), Math.Sin(ay), Math.Sin(az)); R *= circle.Radius; return new BoundingBox(O - R, O + R); } private static double Angle(Vector3d A, Vector3d B) { double dP = A * B; if (dP <= -1.0) { return Math.PI; } if (dP >= +1.0) { return 0.0; } return Math.Acos(dP); }

  • Online PHP/HTML/JS/CSS editor

    - by pistacchio
    Hi to all, is there any free php code that, once installed, allows you to browse and edit files (with html, javascript, php and css highlight) on the server where it's installed? The aim is to code online, browser based. I've tried http://phpanywhere.net/ that can make this possible, but it is buggy and moreover it requires an external (ftp) access to your server that is quite different (and less secure) that working directly on the server. Thanks in advance

  • Recycle a project name?

    - by deamon
    I want to start an open source project, but my favourite project name was already used for a framework with the same goal. This project was never popular, had only two active days with commits at Google Code and is dead since four years. In other words: the project is irrelevant but the name is in use at Google Code and ohloh (the same dead project). The .org domain would be available. Would it be ok to reuse this project name?

  • In windbg, how do I get a heap header address from !heap -l results?

    - by Kevin
    I am playing around with windbg's !heap command, particular the "-l" switch which detects memory leaks. When -l does detect a leak, I am having problems navigating from its results to a stack trace for the source of the leak. Here is a snippet of the results from !heap -l 0:066 !heap -l Searching the memory for potential unreachable busy blocks. Entry User Heap Segment Size PrevSize Unused Flags 0324b500 0324b508 01580000 03230000 20 60 a busy 0324b520 0324b528 01580000 03230000 20 20 a busy 0324b5c8 0324b5d0 01580000 03230000 20 28 a busy Windbg's documentation for !heap tells me to use dt _DPH_BLOCK_INFORMATION with the header address, followed by dds with the blocks' StackTrace field. But the output for !heap -l doesn't specify a header address! It's only specififying Entry, User, Heap, and Segment. I've racked my brain looking over the other commands but can't figure out how to get the header address from any of these fields. Can someone help?

  • Ruby CMS/blog: Mephisto vs. Radiant

    - by Candidasa
    I'm looking for a blogging tool with some light CMS features in Ruby on Rails. I mainly want something simple, but configurable. I have no need for page snippets, etc. Just your basic main blog, very good (and easy) theme support, some nice sidebar stuff, a few static pages and MetaWeblog API support. I'm thinking of either using Mephisto or Radiant CMS (everything else seems half-baked or extremely lightweight at best): http://mephistoblog.com/ http://www.radiantcms.org/ Documentation for Mephisto seems very lacking and their site is a mess. I've also read some bad things about it's stability. Radiant seems more stable in comparison and has heaps of useful plug-ins. However, it isn't designed for blogging out of the box. That has to be added as almost an after thought. Creating a custom theme also seems more cumbersome with Radiant due to the sub-page/snippet feature. Which should I choose?

    I was trying to execute a command through C#, but when I run the following code, a blank cmd window just opens up. The code: string command = string.Format(@"adb install C:\Users\Mohit\Programming\Android_Workspace\{0}\bin\{0}.apk", appName); ProcessStartInfo cmdsi = new ProcessStartInfo("cmd.exe"); cmdsi.Arguments = command; Process cmd = Process.Start(cmdsi); What could be wrong? I am sure the syntax is right.

    - by Thomas O
    Python says I need 4 bytes for a format code of "BH": struct.error: unpack requires a string argument of length 4 Here is the code, I am putting in 3 bytes as I think is needed: major, minor = struct.unpack("BH", self.fp.read(3)) "B" = Unsigned char (1 byte) + "H" unsigned short (2 bytes) = 3 bytes (!?) struct.calcsize("BH") says 4 bytes.

  • How do you pass variables to class_eval in ruby?

    - by klochner
    I'm working on a metaprogramming task, where I'm trying to use a single method to define a polymorphic association in the calling class, while also defining the association in the target class. I need to pass in the name of the calling class to get the association right. Here's a snippet that should get the idea across: class SomeClass < ActiveRecord::Base has_many :join_models, :dependent=:destroy end class JoinModel < ActiveRecord::Base belongs_to :some_class belongs_to :entity, :polymorphic=true end module Foo module ClassMethods def acts_as_entity has_many :join_models, :as=:entity, :dependent=:destroy has_many :some_classes, :through=:join_models klass = self.name.tableize SomeClass.class_eval "has_many :#{klass}, :through=:join_models" end end end I'd like to eliminate the klass= line, but don't know how else to pass a reference to self from the calling class into class_eval. any suggestions?

  • using addListener with WordPress audio player

    - by Jacob
    Hi, I'm trying to add a listener for the stop event in the word press audio player but usage seems to be undocumented. I'm hoping someone who knows a little flash can look at the code and tell me how it works: In the code at http://tools.assembla.com/1pixelout/browser/audio-player/trunk/source/classes/Application.as I see a snippet with this: ExternalInterface.call("AudioPlayer.onStop", _options.playerID); I was hoping that would let me capture the event in javascript with ("player" is the ID of my player) AudioPlayer.addListener("player", "AudioPlayer.onStop", function() { alert('stopped'); }); But my javascript function never seems to get called

  • Is TcpClient BeginRead/Send thread safe?

    - by wb
    Using a dotNET TcpClient if I have called an asynchronous BeginRead() on the associated network stream can I still call Write() on that stream on another thread? Or do I have to lock() the TcpClient in the code that is called back from the BeginRead and the code that does the send? Also if I close the TcpClient with: client.GetStream().Close(); client.Close(); Do I have to lock() on the TcpClient as well? Thanks in advance.

  • Does a custom DataGridView Cell have to have a parameterless constructor?

    - by clawson
    I want to slight variation of the custom cell code example from the MS website How to: Customize Cells and Columns in the Windows Forms DataGridView Control by Extending Their Behavior and Appearance by passing an argument to the custom cell constructor. Public Sub New(ByVal a As Object) End Sub but then when I run the code it throws and exception MissingMethodException occured No parameterless constructor defined for this object. Does this mean that custom cells must have a parameterless constructor? Thanks.

  • Unselect Databound Combobox Winforms .NET

    - by joedotnot
    The problem: combobox is databound to a DataView, first item in the dataview is DataRowView whose fields are DBNull.Value; Combo DropdownStyle = ComboBoxStyle.DropDownList Loads fine, displays fine, selects fine, problem is to Unselect via code. Setting the SelectedIndex to 0 throws an exception. (Setting to -1 is a no-no as per msdn doco that says dont set SelectedIndex=-1 if databound) So how to unselect without throwing an exception ? For now i wrapped it into a try/catch to just ignore the error! EDIT: As asked by Hubeza, i worked on sample code to post. Did a stripped down version of the original code in C# (original is in VB.NET) and could NOT reproduce it either. Converted to VB.NET and could NOT reproduce it either ! In other words, SelectedIndex = 0 does work in the stripped down version! Currently further investigating what else could be wrong with the original code. EDIT2: Case Closed. Call me a stupid fool if you like, and apologies for wasting anyone's time - The error was originating from MyComboBox_SelectedIndexChanged event, which i neglected to check ! May as well post the sample in case anyone finds useful. private void LoadComboMethod() { DataTable dtFruit = new DataTable("FruitTable"); //define columns DataColumn colID = new DataColumn(); colID.DataType = typeof(Int32); //VB.NET GetType(Int32) colID.ColumnName = "ID"; DataColumn colDesc = new DataColumn(); colDesc.DataType = typeof(String); colDesc.ColumnName = "Description"; //add columns to table dtFruit.Columns.AddRange(new DataColumn[] { colID, colDesc }); //add rows DataRow row = dtFruit.NewRow(); row[colID] = 1; row[colDesc] = "Apples"; dtFruit.Rows.Add(row); row = dtFruit.NewRow(); row[colID] = 1; row[colDesc] = "Bananas"; dtFruit.Rows.Add(row); row = dtFruit.NewRow(); row[colID] = 1; row[colDesc] = "Oranges"; dtFruit.Rows.Add(row); //add extra blank row. DataRowView drv = dtFruit.DefaultView.AddNew(); drv.EndEdit(); //Bind combo box DataView dv = new DataView(dtFruit); dv.Sort = "ID ASC"; //ensure blank item on top cboFruit.DataSource = dv; cboFruit.DisplayMember = "Description"; cboFruit.ValueMember = "ID"; } private void UnselectComboMethod() { if (cboFruit.SelectedIndex > 0) { cboFruit.SelectedIndex = 0; } else { MessageBox.Show("no fruit selected"); } }
