摘要：
We present a point-based algorithm for rendering implicit surfaces in R-4. Our algorithm combines a new method for approximating an implicit surface with points which uses interval arithmetic for topological robustness with a new 4D illumination model that together with a color transfer function enhances the visualization of a two-dimensional surface in four-dimensional space.
