Geometric clipping using Boolean textures

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
