-
-- when a node child is a solid leaf the node child number is zero
-- two adjacent areas (sharing a plane at opposite sides) share a face
- this face is a portal between the areas
-- when an area uses a face from the faceindex with a positive index
- then the face plane normal points into the area
-- the face edges are stored counter clockwise using the edgeindex
-- two adjacent convex areas (sharing a face) only share One face
- this is a simple result of the areas being convex
-- the convex areas can't have a mixture of ground and gap faces
- other mixtures of faces in one area are allowed
-- areas with the AREACONTENTS_CLUSTERPORTAL in the settings have
- cluster number zero
-- edge zero is a dummy
-- face zero is a dummy
-- area zero is a dummy
-- node zero is a dummy
