I''m not sure if this should be in the beginners forum or not but I''d like to create a texture procedurally without having to save it on file. I''ve seen D3DXCreateTexture() but I''m not sure how to actually change how the image looks. I was hoping someone could point me in the right direction and save me a bit of time. Thanks.

I would recommend the D3DXFillTexture* routines to generate procedural textures. You can either specify a callback function for the fill routines to call for every pixel, or you can compile an HLSL texture shader for D3DXFillTextureTX to use for filling the texture.
The MetallicFlakes.fx file in the DX9 SDK (use with EffectEdit) demonstrates an example texture shader. The EffectEdit sample is a good demonstration of the C code required to use D3DXFillTextureTX

Question about D3DXFillTexture.

What is the user defined data meant for in the LPD3DXFILL2D function?

[edited by - Chaucer on April 22, 2003 11:03:25 PM]

The user data is data that you specify on the D3DXFillTexture call that is passed to your callback every time the callback is called. This is the standard mechanism for doing callbacks (i.e. see qsort).
Allows you to communicate information to your own callback without resorting to global variables.
