It describes the implementa­tion of a collision detection approach using the Overlapping Axis-Aligned Bounding Box (OAABB) and R-trees to improve petformance. Experimental results show that this implementation is effective in determining interac­tively intersections between 3D models.10.2312/pt.20091235261-267
