MPD files store all map data of a single room, i.e. geometry, enemies, doors, and so on. Textures are not part of the MPD, instead they are stored in the ZND files.

Notes

Polygons are defined as an absolute base vector p1 and offsets p2,p3, and p4 in case of a quad. The offsets need to be scaled, usually by a factor of 8. For example, the absolute p2' is (p1 + p2 * 8).

Todo

Some offset vectors are not scaled by 8. The table, e.g. in 001.MPD (group 4) is scaled by 1. It is unknown where this scale factor is defined or applied. Need to investigate this.
