i want to raycast from a sphere which is emitting into a large scene, the sphere is moving around the scene. Essentially faking a lidar type of look.
As the sphere emits and moves through the scene , the points are raycast to scene objects, and the "scan" builds up.
Everything works as expected , its just that when the sphere is high up it raycasts out to scene objects that are further away than I want it to raycast too .
I can delete these with a outside surface operator no problem , but I thought it maybe a little quicker computing wise if there was a way to raycast with a "max radius" setting ,so to speak. Rather than raycasting to far away objects first , then deleting.
hope that makes sense?
