Star-Contours for Efficient Hierarchical Self-Collision Detection
Orientation and contour tests have long been used as a culling criterion for hierarchical self-collision detection. This paper proposes a novel star-contour test that, together with a thorough analysis of the tree traversal process in hierarchical self-collision detection, provides an efficient yet conservative algorithm.
Subspace Self-Collision Culling
A fast method for self-collision detection of reduced deformable models. The method precomputes certificates, which, if satisfied, guarantee a self-collision-free model configuration.
Volume Contact Constraints at Arbitrary Resolution
A new method for simulating frictional contact between volumetric objects using interpenetration volume constraints. The full-contact modeling process can be implemented on GPU. Contact between highly detailed meshes can be simplified to a single unilateral constraint equation or accurately processed at arbitrary geometry-independent resolution.
Collision-Free Construction of Animated Feathers Using Implicit Constraint Surfaces
A method for constructing complex feather geometry suitable for feature animation. The method is frame-independent and produces visually smooth animation that is free from popping and other visual artifacts.
