| The ActivePolygon Polygonal Algorithm for Haptic Force Generation (2008) | |||||||||||||||
Abstract | |||||||||||||||
| Algorithms for computing forces and associated surface deformations from a polygonal data set are given, which can be used to haptically and graphically display virtual objects with a singlepoint cursor. A culled collision detection algorithm is described that works in real-time with large data sets utilizing an oct-tree method. After a collision is detected, forces are created based on the local area near the cursor, keeping track of an active polygon. This creates a method that is effective and scalable for large models. The ‘Bendable Polygon ’ algorithm for visual rendering of computer generated surfaces is also given. | |||||||||||||||
