• Stuart A. Malone colorvalue in progressive mesh sample

  Hi, new to DirectX in C#, not in C++. In the August 2005 DirectX sdk update, there is a sample in C# called "Progressive Mesh".  When I compile this sample, I get 36 errors, all of which are type or namespace missing errors.  Here's an example.  'ColorValue', which is supposed to be of the Microsoft.DirectX.Direct3D namespace simple does not appear to be there.  MSDN says it's part of the namespace, auto-complete does not.&nb ...Show All

  Hi, I am trying to get the force feedback feature to work with VB.Net but not able to do so. Basic features work fine. The C# sample provided with the DirectX9 doesnt seem to work.

  Hi! How to create an application template like the one presented here: http://msdn.microsoft.com/coding4fun/weekend/apptemplate/default.aspx , but for .NET 2.0 I'm new to the whole .NET thing and it's quite confusing for me.

• ilango2006 retrieving more than 4 values per texture lookup

  Is it possible to have a texture with more than 4 values per texel My problem is, I need to look up a chunk of many values (about 16) multiple times per pixel and I like to do that quickly. In my setting more than three 2d texture lookups each time (= 12 float values) is the maximum I can allow without a significant performance drop. Also if anybody has experimented with 64 or 128 bit textures I'm interested to know about the performance ...Show All

• GrandmaGG DirectSound under VS2005 - null reference using buffer notifications

  Hi, I'm very new to DirectX. Using VS2005 and the December 2005 SDK I have created a very simple winforms app that plays a WAV file. This works fine. I then tried to add buffer notifications specifically so I could detect when playback stops. Immediately though I hit a stumbling block, when I instantiate a new Notify instance I get a null reference exception. The buffer parameter is most definitely not null. This is a cut down version o ...Show All

• Osmar Getting Started Is Hard

  [rant] Ok I know I want to learn DirectX and be able to write my own DirectX wrapper in a high level, like Plotting a point would be as simple as calling: ClassName2d.PlotPoint(var,var,var); Then use that to write a 3d game engine including physics, sound, input, networking, graphics etc. Then use the engines to start making games. Now I know that this will take a ton of time to be able to do this, especially for one programmer. Even if my g ...Show All

• bw_123 Simple example for February 2006?

  Hi, I just installed the February 2006 version of the SDK (I'm using .net 2.0) and I find the examples to be a bit overwhelming for a beginner. I'm experimenting with the first two: EmptyProject and EnhancedMesh From the EmptyProject I see that the framework is an awsome tool but the problem is that so many things are hidden. So I was wondering if anyone has an example build on the dx framework(EmptyProject) of presenting a simple m ...Show All

• skinnedabyss Reading a Vertexbuffer from a Mesh

  This has been driving me nuts.  It's so simple... but not working.  I have written to vertex buffers before, no problem.  But, for some reason, I can't read an existing one from a mesh. Keep in mind, I have recently upgraded to the newest version of Managed DirectX. Perhaps something has changed   I would like to dump vertex buffer into an array so I can get the locations of all the vertices.  (Eventually, I ...Show All
