Re: Building Model Generator

[Sean Markan <markan@MIT.EDU>]

Anders,

If I understand what you're asking, we didn't encounter this problem
because the CAD floorplans we worked from already had a layer on which
each room was a complete closed contour.  We used those contours to build
representations of each room.  Some of the publications (e.g. Rick
Lewis's) at http://graphics.lcs.mit.edu/~seth/pubs/pubs.html might be more
useful though.  If you have further questions, you could also try asking
the current BMG members (bmg@graphics.lcs.mit.edu).
