In Response To: Doom 3 portal rendering (ehyto)

: To make an advanced Marathon engine, I could take from Doom 3 and Aleph One.

: Doom 3 and Aleph One are both GPL licensed.

: Use Doom 3 portal rendering with polyhedron shaped rooms.

: The rooms are convex polyhedron.

: Don't use BSP trees, use directed a cyclic graph.

: Use mathematical planes to find portals and point in polyhedron.

: Collisions with capsule to capsule and capsule to triangle.

: Made it with Unity, but I'm looking at OpenTK and object oriented
: programming.

Did id Tech 4 always support portal rendering? I know it did by the time Prey came out but I don't know about when Doom 3 did 2 years previously.
