I'm looking for ways to efficiently store/display geometry with "flat" facets. That is to say, I want "all" creases (no interpolated normals). I'm reading some hefty geometry (10-20M polys) for display (Currently in OBJ format). There are only hundreds of unique normals. The OBJ loader tristrips everything and computes per-vertex normals.
Since I'm bumping up against the memory address limit on 32bit machines when using this geometry, I'd *really* like to recoup the storage for all those (redundant) normals. I think using short ints for 'normal indexes' instead of per-vertex normals would buy me a fair bit of space. Can anyone offer any pointers/guidance?
