Smooth Surface Representation over Irregular Meshes
- 218 Downloads
The previous chapter has described a number of surface representation schemes in surface modeling. These schemes, despite being popular in geometric modeling, do suffer from one important limitation: the control mesh must be structured to have a rectangular topology. This limitation has made it very awkward for many modeling tasks in computer animation, such as the modeling of branches and non-quadrilateral patches.
