Abstract:
PURPOSE: A parallel collision detection method based on inter collision detection and a computer readable media thereof are provided to minimize the locking by distributing the task efficiently when the collision detection of an object is executed using a plurality of threads. CONSTITUTION: The bounding volume hierarchy(BVH) for objects is created based on the geometric information of objects(S110). The main BVH is created based on the BVHs of the objects (S120). The subtrees in which the reciprocity irrelevant nodes are the root are extracted from the main BVH(S130). The nodes composed in the subtrees are distributed to each of threads(S140). An inter collision test pair set(ICTPS), which is a set of the node pairs composed in the subtrees, are created for performing the collision detection between the objects for the parent node of the nodes(S150).

Abstract:
PURPOSE: A hybrid parallel continuous collision detection method using a CPU and a GPU(Graphics Processing Unit) is provided to guarantee high expandability of collision detect when a number of thread is increased. CONSTITUTION: A main BVH(Bounding Volume Hierarchies) is generated by combining each BVH of objects(S120). A basic polygon pair information of collision test object is inputted in TIQ(Triangle Index Queue) among the basic polygon which is included in the main BVH. The basic polygon pair information of collision test object which is inputted in the TIQ is transmitted to the GPU(S140). The GPU performs collision test for the basic polygon pair information of collision test object(S150).

PURPOSE: A multi-resolution clothing simulation method and computer readable recording medium are provided to increase performance without dropping down the simulation quality of computer readable recording medium for storing a command. CONSTITUTION: A linear system is configured by using a mesh structure for a first area(S10). Simplification probability of the first area is determined based on geometric information of the first area(S20). The linear system is simplified according to the simplification of the first area(S30). A solution of an original linear system is obtained from the simplified linear system(S40). An error about the solution of the linear system is modified(S50).
