Hello, I have an application that includes several primitive objects (10-200). Now I want to manupulate the scene: Let's say, I only want to see the red objects, or only all cones, or I want to remove single objects in the scene. What is the best solution to solve this problem? Should I use a SwitchGroup or is it better to set the child with the setChild method of the group node? Has somebody an idea?
