Image Description, by
Steep Parallax Mapping is a straightforward change to a pixel shader that
allows a game to render existing parallax maps with increased detail. The new
effects possible include 1-pass fur and grass, bumps with vertical edges, bump
self-shadowing, and a general correction to the texture-swim problems of
parallax mapping.
The left image shows a flat wall with all detail rendered via Steep Parallax
Map. The image is rendered at 1024x768 with 4x FSAA at 30fps on GeForce6800.
The right image shows fur rendered using the method at the same frame rate.
Details, images, and a discussion of similar methods recently proposed are
posted on our website,
