   HLSL intrinsic noise
  Hello. Whats the deal with the noise function? How can we set the alpha, beta, and harmonics? The MSDN doesn't say anything about reseeding random values or anything.   
  Moving to the DirectX forum since this appears to be about accessing shader language features rather than about math or physics.   ;  The deal is that no hardware actually supports it.  The only place you can use it is if you're using an ID3DXTextureShader to procedurally fill a texture, since that runs the shader on the CPU.   ;  Yeah I've wondered why they dont implement it in the hardware.. its would be very useful.   ;  Thanks, sorry about wrong forum grhrodes
