Ray-traced collision detection for deformable bodies

Everton Hermann, Bruno Raffin, Fran├žois Faure:

Abstract:

This paper presents a new approach to collision detection and modeling between deformable volumetric bodies. It allows deep intersections while alleviating the difficulties of distance field update.
A ray is shot from each surface vertex in the direction of the inward normal. A collision is detected when the first intersection belongs to an inward surface triangle of another body.
A contact force between the vertex and the matching point is then created. Experiments show that this approach is fast and more robust than traditional proximity-based collisions.
