Appropriate application of spatial coherence can speed up the collision detection of moving objects without sacrificing accuracy. This paper presents an automatic method applicable to convex polyhedral objects that can undergo both uniform scaling transformation and any type of relative motion for computing the range of motion for spatial coherence, i.e.(More)

This paper first presents the decision curve as an economical way that describes the correlations between scaling pairs (rho<sub>1</sub>, rho<sub>2</sub>), small relative motion conditions (type, direction and amount) and contact configurations (feature) of two scaled convex polyhedral objects where rho<sub>i</sub> denotes the scaling factor of polyhedral(More)
