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.bekindtopets.com/mega-super-Motor-Brush-for-the-Pride-Celebrity-2000-SC4400-and-Sundancer-SC2000-flash-save/
