Dynamic Collision Detection in Virtual Reality Applications
We present data structures and algorithms for dynamic
collision detection in virtual reality applications.
The methods are applicable to all general polygonal models.
They combine the advantages of collision detection using bounding
volume (BV) hierarchies with the ability to compute dynamic
collision detection results.
The results are used as input for further simulations, e.g. contact
or dynamics simulation.
First we present new methods to compute BV hierarchies using
optimization goals which can also be used to improve known computation
methods.
Second we show how to integrate BV hierarchies into a process of
dynamic collision detection, so that the bounding objects as
well as the surface patches of the objects are tested for overlap
during their motions.
The performance of the techniques is shown by means of a fitting
simulation in the automotive industry.
