Abstract: Virtual prototyping of mechanical systems requires efficient
and robust geometric algorithms in its core. We present algorithms for
collision detection and distance calculation, which can be used in
interactive virtual reality applications in order to perform ergonomy
studies and assembly planning tasks in automotive industry. Avoiding
the interpenetration of the virtual objects and modeling their
physical behavior when they collide are a prerequisite for
realistically simulating assembly operations in a virtual
environment. We report on experimental results we achieved together
with our cooperation partner, the virtual reality competence center of
DaimlerChrysler.
As further industrial applications we discuss algorithms for computing the reachable space of mechanisms (e.g. the steering column of a car) or measuring the trunk interior of a car by solving a packing problem. |
