| Abstract | Goldfeather et al. [1], [2] introduced an algorithm for rendering Constructive Solid Geometry (CSG) on Z-Buffer hardware that was later improved by Stewart et al. [4] resulting in the Layered Goldfeather algorithm. We present an improved version of the layered Goldfeather algorithm that retains its capability of rendering concave objects and of using depth complexity information for potentially reducing the amount of rasterization that is needed. Our new algorithm is not prone to the z-buffer precision problems of the layered Goldfeather algorithm and can thus be used with standard OpenGL implementations. This improvement is based on the use of stencil planes for intermediary results of the rasterization process, thereby potentially decreassing the necessary bandwidth between graphics hardware and main memory. |
