Description

State to collect the GeometryNodes that are going through a rendering channel. The set of collected nodes can be retrieved at any time. It is cleared when the state is activated. If combined with a culling renderer, this state can be used to collect the potentially visible set (PVS) that is created by the culling renderer.
