Portal Test Demonstration
A top view of the collection of convex regions is shown in Layout.png. The
floor is z = 0 and the ceiling is z = 1. Each cubic region is 2x2x2. The
13 regions are named as shown in the image. The portal indices for each
region are also shown.
The convex region manager uses a BSP tree to partition space into the
appropriate regions. The BSP tree for this layout is in BspTree.txt.
The tessellation for the center cube is shown in WallTessellate.png. This is
a top view with the ceiling removed. The four portals are shown. The end
cubes centered at (4,0), (-4,0), (0,4), and (0,-4) have three portals each.
The tessellation is shown in EndTessellate.png. The 8 connector regions have
two portals each. The tessellation is shown for the axis-aligned connectors
in ConnectorTessellate.png. The connectivity array is the same for the
diagonal connectors; only the vertex geometry is different.
Yes, the artwork is awful. I am an engineer, not an artist :)
