Abstract: Shadows are of great importance to computer graphics, especially for interactive animation, due to the visual cues which they provide. Most research in the field of dynamic shadowing has focussed on shadows from point light sources, since they are much easier to compute than those from area lights. This means that such shadows have sharp boundaries, and so resultant visualisations often appear sterile and unrealistic. We use discontinuity meshing as the underlying mechanism for shadow...

...respect to increases in shadow complexity. The time taken for migration detection does not vary much. This is described in more detail in [17]. Effect on migration processing. When a discontinuity line makes a migration, we cast a partial wedge through the subset of the scene...
