[WIP] Flash quake/descent style renderer.

[rachil0]

Not easily. In a portal renderer, faces have to be collected into convex polyhedra which enclose player roamable space. There is no such thing as a polygon in isolation, it's always bound to exactly one polyhedron.

Descent maps can only be translated/loaded easily because it stores these polyhedral groupings inside the level file. In quake (and sequels), this representation is not made very explicit. Every leaf of the BSP tree defines a polyhedron, but to actually build that polyhedron requires a lot of clipping operations. For loading a quake map it would be more of a reconstruction process, not a translation process.

EDIT: Thanks renderhjs You set the bar high.
