Therefore, they require less storage and/or transmission capacity. Furthermore, they allow automatic level-of-detail. Finally, they result in considerable savings in model-view transformations and lighting calculations. We present two algorithms for rendering these triangles, each of which can be easily incorporated in hardware render systems currently used for planar triangles.1.3.3 [Computer Graphics]Picture/Image Generationdisplay algorithms1.3.5 [Computer Graphics]Computational Geometry and Object ModelingSurface representations.
