Texture shaders

Shaders probably run on the GPU or crash on the CPU. [grin]

depends on if you support vertex/pixel shaders in hardware. if you do, they run on the gpu. if not, they run on cpu.

Well, the reason I ask is that there are D3DXTextureFill() functions which take C functions which are executed each pixel, and they're blatently not going to be executed on the GPU. It's only the D3DXTextureFillTX() function which takes a texture shader interface (it used to be just a compiled shader code pointer!) so I'm not sure if it's actually going to use the GPU, or if it's just a convenience method. The docs don't say anything about where it gets executed, which is annoying.

I seem to recall it always runs in software. However, the return value docs say:

Quote:

If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_NOTAVAILABLE - This device does not support the queried technique. D3DERR_INVALIDCALL - The method call is invalid. For example, a method's parameter may have an invalid value.
