The Persuit of PaperKing - Days 9 & 10

The last couple days have been spent on getting the track structures built.  The track that is being used will consist of 3 "wires" for the track.  This seems like a good trade off between aesthetics, and low polygon count.  There are also some "braces" that are at each end of the segments, these are made of a cube that is "bent" so the curve matches the geometry of the "wires", giving an enhanced look.
In getting the track segments into a "build" function, the track was pretty easy to build, time consuming to get all the curvature and positioning to a style that we liked, but not technically very difficult.
Getting the 4 polygons for the physics engine to match the track proved to be a little tricker.  First of all the coordinate system between wow and papervision seems to be reversed.  Second you can't attach a polygon to a wow particle (or vise-versa) so everything needs to be positioned twice.  Third, the wow particles don't have a container system (at least not that we found) like papervision does, so the calculations all need to be done by hand (back to Trigonomotry).
