Detailed Description
Shadow3DExtractingProcessor class.
This processor extracts the 2D shadow geometry (projected geometry) of all fed primitives. It is used to create the shadow of 3D objects which consists of 2D geometry. It needs quite some data to do so since we do not only offer flat projected 2D shadow, but also projections dependent on the light source
