We propose an analysis of numerical integration based on sampling theory, whereby the integration error caused by aliasing is suppressed by pre-filtering. We derive a pre-filter f...

Creating an appropriate mesh is one of demanding tasks of many global illumination algorithms. Discontinuity meshing proved to diminish artifacts caused by other meshing strategie...
