Texture Loading

Load the raw data (obviously ), create a texture in the preferred format via IDirect3DDevice8::CreateTexture(), get a pointer to the surface using IDirect3DTexture8::GetSurfaceLevel(), lock and fill it with your data. The last step may involve some format conversion but should not be this hard to do - at least in d3d8.

Hope this helps,

thx

Correct me if I''m wrong, but GetLevelSurfaceDesc() doesn''t return a pointer to the surface as far as I know. I think you have to call LockRect() to get a pointer to the surface, and the sad thing is, video memory surfaces can''t be locked by LockRect()

The way I''ve been doing it is creating a D3DPOOL_SYSTEMMEM texture, locking it, copying my image data to it and then calling UpdateTexture() on my video memory texture..

Am I doing this extra step for nothing?

Yup, GetLevelSurfaceDesc() does not, but GetSurfaceLevel() does The returned surface is lookable even if the texture is in D3DPOOL_DEFAULT (at least according to how I understand the docs )

I had overlooked that method, but according to testing I just did, the returned surface doesn''t seem to be lockable.

Of course, if D3D8 returned something other than that blasted D3DERR_INVALIDCALL from time to time, it would be easier to know what went wrong exactly.. But the call to LockRect failed on the surface, and I don''t feel like installing the debug version of Dx8 to find out why
