SiLVIA
Simulation Library for Virtual Reality and
Interactive Applications
:

Goals:
  • build a system to simulate the dynamics of rigid bodies and
    to interactively manipulate these bodies in virtual environments
  • support objects geometrically described by planar as well as curved
    surfaces
  • provide realistic simulation of physical effects like impacts, sliding,
    sticking and rolling motions friction
  • develop efficient algorithms for collision detection and
    distance computation.

Exacus
Efficient and exact algorithms for curves and surfaces:

Goals (cf. presentation of Kurt Mehlhorn):
  • long term: create the basis for the next generation CAD systems
  • more concretely: build a system for exact and efficient computational
    geometry and solid modeling with curves and surfaces
  • develop and extend the underlying theory
  • by analogy: a LEDA/CGAL for the curved world.
