• jerrison pixel shader computation: precision problem?

  Hi, I do the following computation in a pixel shader:   const float texel = 1.0 / 128.0; result = floor(In.texcoord.w / 16.0) / 64.0 + texel   In.texcoord.w containes an integer value between 0 and 299, stored as a float, interpolated over the triangle, where each vertex stores the same value, so in practice there shouldn't be any interpolation happening.  When I output result as a color, I notice distortions ...Show All

• DavidATaylor Drawing textures with transparent and semi-transparent texels?

  Hello,      I have a texture and I'll draw it in 2D view, I try to make some texels of it fully transparent and the other is some transparent.

• e-mhigz Rotation about the z-axis...

  I have a square on screen (2 triangles), and I'm experimenting with rotating the thing. Rotating about the x and y axis works as expected (the thing spins horizontally and vertically), but when I rotate it about the z-axis, it goes up and down, deforms a bit, and just looks weird. As for how I'm doing it right now, I'm using Matrix.RotationYawPitchRoll(x, y, z) to get my rotation matrix. ...Show All

• sugus_29 Unresponsive Visual Studio during build

  I have a nice, dual-core build machine with RAID-1 Raptor 150 disks and 2 GB of RAM -- typically, I can keep working while building in the background on this machine. However, when using XNA to build the MC2 sample, the Visual Studio window was mostly unresponsive duing the 7 minutes and 14 seconds it took to build. Most of that was because it spent 532 seconds in the CreateTGL stage, during which clicking anywhere in the Visual Studio window di ...Show All

• Stefano B Where can I get volume textures?

  Does anybody know where I could find some free volume textures to play around with Nico Thanks, I will have a look at it. Probably the reason why I cannot find any volume textures (with geometry) in it, is that they are not widely used yet but that could change. I'll let you know when I have written the mesh-to-volume-texture tool. The extension of your tool is a nice idea, but currently I'm using C++. But ...Show All

• denesh Unit size

  Hi, I don't understand how to define units in my model and world space. I have loaded a mesh, and if I don't scale it down it is very large. When I modeled it in a 3d modeler i modeled it to be about 50cm X 50cm X 70cm. When I load in the mesh it is very big. I want to define it so that 1 unit = 50 cm. And the screen is about 10x10 units. How can I do this I you don't understand my question, please tell me and I will try to explain my problem in ...Show All

• Sir_Penguin Pass int array to the pixel shader

  I want to pass an int array to the pixel shader.  I used SetIntArray(name, val)..the problem is that in the shader I do not know the exact size of the array, therefore in declaring it i am trying to use an int *.  It seems as if the compiler does not like this. Is is it possible to use pointers in the shader   If not how can I pass a variable length array to the shader can someone give me an example of the usage of this function ...Show All

• nbnb Seting Boundaries

  What is the best way to set boundaries in a flight simulation type application in a 3D enviorment Can you explain more what you mean, its not clear to me what you want. Well since you know the x,y,z position of your player you can check that against suitable bounds. e.g. if (x>1000) or (x<-1000) then 'out of bounds' Or you could do a distance check from the origin e.g. Vector3 posi ...Show All
