while building it. That may improve performance, by building a more
balanced tree and actually reducing splitting. Not dramatic
improvements, though; half the triangles for some parts, but no
change or slightly worse for others.

set of coplanar faces. The polygon count still gets stupid fast;
I'm thinking I can fix that by adding some extra test planes at the
top of the 3d BSP, to quickly cull out stuff that doesn't intersect
us.

a triangle mesh in a BSP. That works, although it splits too often,
the initial triangulations are not good quality, and coplanar faces
are not yet handled. I'll do the coplanar thing tomorrow.

for that, and storing the triangles instead of rendering them
immediately. Not sure if that's smart; in theory could change from
implementation to implementation, but the results look much better
than I would get myself.

not very well; I'm doing a b-rep, where the boundaries are complex
polygons, and there's too many special cases. I should probably
replace this with a triangle mesh solution.

constraints work mod 180 degrees, so that it snaps to however the
workplane was drawn (more vertical vs. more horizontal).

workplanes. And fix up our polygon normals, so that everything gets
shaded correctly (and so that later we can generate our STL files
with correct normals).

faces of the polyhedron. And shade the faces when I draw them, and
fix up our projection matrix so that the depth testing works
properly.

issues, when the points are not all in the same coordinate system.
All painful, of course. Also add continuous line drawing, and
auto-constraining of line segments as I draw.
