In this paper. we propose a method to visualize large-scale colliding point clouds by highlighting their collision areas. and apply the method to visualization of collision simulation. Our method uses our recent work that achieved precise three-dimensional see-through imaging. https://www.roneverhart.com/Fire-Retardant-Premium-Polyester-8ft-Rectangular-Tablecloth-Ivory-Fitted-High-Performance-Table-Cover/
