It is also * possible to copy a D3DSurface to another D3DSurface (or to itself). * * D3DTexture * This kind of surface cannot be rendered to using D3D (in the same sense * as in D3DSurface). However, it is possible to upload a region of pixels * to a D3DTexture object via Lock/UnlockRect(). One can also copy a * surface of type D3DTexture to a D3DSurface by binding the texture * to a quad and then rendering it to the destination surface (this process * is known as "texture mapping"). * * D3DSurfaceRTT * This kind of surface can be thought of as a sort of hybrid between * D3DSurface and D3DTexture, in that one can render to this kind of * surface as if it were of type D3DSurface, but the process of copying * this kind of surface to another is more like a D3DTexture. (Note that * "RTT" stands for "render-to-texture".) * * In addition to these SurfaceType variants, we have also defined some * constants that describe in more detail the type of underlying D3D * surface.
