Detailed Description
The GeneralPointLight node specifies a point light source at a 3D location in the local coordinate system.
A point light source emits light equally in all directions; that is, it is omnidirectional. GeneralPointLight nodes are specified in the local coordinate system and are affected by ancestor transformations.
