Abstract—After the depth/RGB camera Kinect was firstly developed by Microsoft around 2010, an object is frequently captured and simultaneously is dealt with a set of point crowd. Therefore, we have been focusing on algorithms concerning to overlapping two or more crowds, distance calculation between two or more crowds, intersection check between two more crowds. On these circumstances, we focus on how to generate an artificial force with arbitrary direction and magnitude when two or more objects are interrupted each other in this paper. Needless to say, their objects are expressed by digital data such as point cloud, voxel cloud, sphere cloud, and their hierarchical structure in positioning. In this method, collision detection area, cuttable area, and representative point are set freely. As a result, we can select to calculate one of various normal vectors flexibly and rapidly even for rigid bodies or soft tissue composed of multiple materials. In this circumstance, we propose a novel algorithm which generates an artificial force flexibly when digital clouds are encountered each other.
