PROBLEM TO BE SOLVED: To offer technique of solving problems that contact determination is not completed in case the pointer is the inside of a body when touching an object which moves itself, and performing the contact determination of a dynamic model and the pointer at a high speed in an application which touches three-dimensional models within a computer using a tactile sense profiling device. SOLUTION: A polygon model used as a key frame is created (a step 100), the computational complexity of the contact determination is reduced by creating Octree (a step 102), and by utilizing Offset corresponding to a dynamic deformation (a step 108), the contact determination of the dynamic state and the pointer is performed to display the tactile sense (a step 124). Therefore, the contact determination of the dynamic state and the pointer can be performed at a high speed and it becomes possible to touch the dynamic state realized within the computer using the tactile sense profiling device.
