Geometric displacement on plane and sphere
This paper describes a new algorithm for geometric displacement mapping. Its key idea is that all occluded solutions for an eye ray lie in two-dimensional manifolds perpendicular ...

Entkerner: A System for Removal of Globally Invisible Triangles from Large Meshes
We present a method that computes a global potentially visible set for the complete region outside the convex hull of an object. The technique is used to remove invisible parts (t...

Interactive Simulation of the Human Eye Depth of Field and Its Correction by Spectacle Lenses
This paper describes a fast rendering algorithm for verification of spectacle lens design. Our method simulates refraction corrections of astigmatism as well as myopia or presbyo...

Enhancements to Directional Coherence Maps
Directional Coherence Maps as proposed by Guo in '98 are a very efficient acceleration technique for ray tracing based global illumination renderers. It vastly reduces the nu...
