Collision detection for high-resolution deformable object using particle-based approach

Computational time of collision detection can be exceeded when there are too many checking for non-colliding primitives on some particular areas of high-resolution deformable objects. The problem is usually solved with best-fit bounding volume hierarchies (BVHs) which require much more memory and time for updating the bounding volumes when the objects deform. Hence, a particle-based collision detection method is enhanced to reduce the checking for non-colliding primitives by adding movable particles on the object vertices corresponding to each particular area. The distance of corresponding particles are computed for selecting the closest vertices between each pair of objects. The experimental results show that the proposed method has less colliding checking time than using BVHs when using with the deformable objects. Moreover, the proposed primitive-checking method can be parallel processed on GPU increasing speed performance while accuracy is still preserved when the results are compared to the previous BVH method.
