Check if the point is visible

[wolf]

Since you want to do a selection, maybe this snippet could help you. It uses a simple glsl shader for picking objects and could probably easily be enhanced to work for a region rather than only the mouses position. It’s also faster than using collision rays. It does require a property on each pickable object but I guess that needs to be done in most any cases anyways to make things selectable.

Picking visible models

Hey all, with the help of @rdb I recently created a little script to pick any 3D objects without the need of using a collision detection system but only a simple GLSL shader. The sample shows how to set up the scene and handle the actual picking. Hope you’ll find this useful.
