  • TEX2D 2nd overload: HLSL Bug or erroneous usage?

      • Greetings to all Forum Members and an amazing 2007 to everyone! DESCRIPTION: I'm doing a shader that uses the seccond overload of Tex2D to do a Texture lookup (source rect) before stretchs it with the Texcoord. So I did declare the float2 to store the source rectX and rectY in the parameters as follows: // My Shader texture Mytexture < string myfile = "TexFilename" ;
  • VertexBuffer.SetData cost

      • Which is faster -Add vertices a few at a time to an array, then call VertexBuffer.SetData for all of them at once -Call VertexBuffer.SetData on a few vertices several times The array can be statically allocated, but the data is only relevant for one frame, so there's no benefit to keeping it around. Thanks, Max

      • I was wondering if anyone has had any success with the XNA framework on a pc with the Intel 915G chipset. I have a user reporting an XNA-based program of mine is failing to start up due to it being unable to find a suitable graphics device. Reading around on various forums, I gather the shader support offered by the Intel 915G is somewhat non-standard, which may explain why XNA can't or won't use

      • This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the c

I'm thinking about building my engine in a modular fashion so that I can issue pluggins to extend its abilities easily. The XNA documentation lists System.Reflection.Assembly as an supported object on the 360. Is this true, and how does the FromFrom, etc methods work on the 360. Obviously the file pat

I also found DXGI_ GAMMA _CONTROL that seems to be used to convert back from gamma 1.0 to 2.0. With D3D9 there was also a SRGB render state. I would appreciate an explanation how this works now in DX10. What
