Geometric clipping using Boolean textures
William E. Lorensen · IEEE Visualization · 1993
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. >
