Abstract

Texture mapping is normally used to convey geometric detail without adding geometric complexity. This paper introduces boolean textures, a texture mapping technique that uses implicit functions to generate texture maps and texture coordinates. These boolean textures perform clipping during a renderer's scan conversion step. Any implicit function is a candidate boolean texture clipper. The paper describes how to use quadrics as clippers. Applications from engineering and medicine illustrate the effectiveness of texture as a clipping tool.
