Hi guys, I would be glad if anyone of you could let me know if there is a function in Direct3d which can be used to copy elements from a texture and put them into another texture. thanks.

IDirect3DDevice9::UpdateSurface() or IDirect3DDevice9::UpdateTexture() will do the trick. IDirect3DDevice9::UpdateTexture() won't let you specify a subsection of the texture to copy though.

You can get a surface from a texture via IDirect3DTexture9::GetSurfaceLevel().
