Programming Notes

The FishEye sample scene is rendered into the surfaces of a cube map, rather than the back buffer. Then the cube map is used as an environment map to reflect the scene in some distorted geometry—in this case, some geometry approximating a fish eye lens. See the Cube Map Sample for more information about cube mapping.

This sample uses common Microsoft?DirectX?code that consists of programming elements such as helper functions. This code is shared with other samples in the DirectX software development kit (SDK). You can find the sample framework headers and source code in (SDK root)\DXSDK\Samples\C++\Common\Include and (SDK root)\DXSDK\Samples\C++\Common\Src.
