Abstract
In this paper, a simulated three-dimensional virtual world is created with a virtual 3D space ball for virtual object control. We propose a new technique called HV Partition to detect accurate collision on the assembly of two polyhedral solids in virtual simulation. This is a solid-based detection methodology achieved by automatically partitioning the object into smaller solid boxes. Mechanical components, represented by nonconvex polyhedra, traversing any degree of freedom, are applied in this environment. Using this HV Partition method, the accurate interference between two polyhedral objects can be found. The HV Partition methodology is applied following initial approximate collision detection using traditional bounding box and bounding sphere methods. The smaller the number of smaller boxes, the quicker is the performance of the collision algorithm. An automatic partition method is also given to reduce the number of smaller boxes in an object.
