WebMay 18, 2024 · Threejsfundamentals.org describes Raycasting or Object Picking as “the process of figuring out which object a user clicked on or touched”. Essentially, a pointer is cast from your mouse or finger (on mobile) through the frustum of the scene to the object that it intersects. This method is great in order to perform logic on a specific object. http://www.open3d.org/docs/latest/tutorial/t_reconstruction_system/ray_casting.html
