Abstract:
This project presents a new, and more versatile, method for performing Relief Mapping (also known as Parallax Occlusion Mapping), utilizing rates of change in texture coordinates across a polygon surface to calculate the texture sampling offsets used in the ray-tracing portion of the Relief Mapping algorithm. This new technique relies solely upon the texture-coordinates, vertex-coordinates, and a depth-map texture, allowing Relief Mapping to be utilized on complex meshes without the need for additional per-polygon information such as texture-aligned tangents or normal maps.
