[MOAB-dev] Creating geometry from sets of triangles

[Paul Wilson]

Hello MOAB team,

I'm looking to write a new reader for MOAB to read wavefront (obj) 
files.  These are sets of triangles - I think very similar to STL files 
- that enclose volumes.  (STL may be another option here actually.) In 
the primary geometry of interest, there are nested regions of space, 
each enclosed by a set of triangles.  I'd like to generate a model a la 
DAGMC that correctly excludes the nested volumes from its parent, etc.

It seems that something like this perhaps exists already, either in 
MOAB, or CGM, or Cubit, and I wonder what advice the MOAB team has for 
accomplishing this.  I've thought about some algorithmic notions to do 
this, but didn't want to get too far down the implementation without 
checking here first.

Paul
