Re: topology files

Some replies:

- portals do have a well defined source and dest. HOWEVER, portal's don't have a notion of directionality. Do you think this is a serious problem with the model?

- some times portals have an explicit type in the data (stairs vs. elevator shafts vs. windows), and it probably makes sense to save those types rather than inferring them from bell's code. ergo, we save them in their text representation. additionally, i'm not really sure how to go about inferring portal types in certain scenarios -- i.e. its really unclear how to tell an elevator shaft from a staircase, and they are very different times.

portals should have a well-defined source and dest

why do portals have types?  shouldn't a portal
be able to infer its type from the type of its
destination space?

this is for patrick especially,

here's a quick spec for the (new) topology output from walls:
http://graphics.lcs.mit.edu/~mic/bmg/topology.html
it's not quite formal but it's a pretty dead-simple spec.
