# Manifold

Portal renderer for Sega Genesis/Megadrive.

Uses a "2.5D", doom or build engine-style rendering pipeline, but with convex sectors and portals.

Graphics features

- Arbitrary angled walls, ala doom and build-engine. 

- Perspective-correct texture mapping

- Sector-based lighting levels with per-pixel distance lighting.

- Overlapping "non-euclidean" geometry

- Transparent surfaces.
