A very rough set of routines to triangulate by ear clipping. This is O(n^2), not perfectly robust, and the bridge-finding code is particularly bad. But it works, triangulates, and shouldn't ever generate zero-area triangles like gl does.

Early attempts at rational polynomial surfaces. I can create one from an extrusion, with piecewise linear trim curves for everything (that are shared, so that they appear only once for the two surfaces that each trims). No Boolean operations on them, and the triangulation is bad, because gl seems to merge collinear edges.

SPolyCurve (i.e., polynomial curve) vs. SPolygon got too confusing; let's call those Beziers instead.

Generate the group's polygon from the exact curves, not from edges; so now we've got the exact curve loops, with their direction standardized so that we can tell which direction is out. We still need the polygon in any case, since that's a convenient way to find each curve's winding number.

Remove old sweep/helical sweep code for meshes, and add some untested stuff to start making exact surface shells.

Entities now generate rational polynomial curves instead of piecwise linear segments. These are piecewise linear approximated for display, and currently for the mesh too, but that's the first step to replace the mesh with exact curved surfaces.

Split export DXF command into export section and export view, and add framework for additional vector output formats (ps, pdf).

Add menu item to center view at a point; and move non-ID list data structure from polygon.h into dsc.h, since it is used outside the polygon/mesh code.

Tolerate files with \r characters in them; we would never write such a file, but mailers might mangle them.

Add a constraint to make line length equal arc length. That's quite tricky; can't just use the dot product, since that blows up when you cross pi radians. A gear shift approach, use either sin or cos, same kind of thing as the 3d-parallel constraint.

Oops, Windows timers are periodic. So after displaying a tooltip, we repainted once every second thereafter...

Don't let the user create workplanes locked in another workplane; that is almost surely a mistake.

Add feature to find the degrees of freedom; strike the corresponding to each param from the Jacobian, and see if it loses rank. If it does then that one was important, so it's bound. Then display a big blue square around its point until the next normal solve.

Split constraint.cpp into two files: one for building the constraint structures based on user input, and one for generating equations from the constraints.

Add a trim command. I can now do circles (or arcs) against lines, or lines against lines. The constraints get rather screwed up afterwards, of course.

Add a toolbar. This requires a tool to convert my PNG icons to tables in the code, which I have written in perl and am checking in.

Auto-show the text window when stepping a dimension, in addition to auto-showing when a solve fails. And accept expressions, not just numbers, for that new dimension value.

Change fudging when I select edges to generate a section from the shell. That seems less prone generating stray lines, though it does sometimes generate gaps.

Auto-remove point-on-line constraints when at-midpoint constraints are added. There was already precedent for that, since I auto-remove horiz/vert constraints when symmetry constraints are added.

Speed up the inconsistent constraint detection; there's no reason not to solve by substitution before rank testing. And report the unsatisfied constraints when we don't converge.

Fix the mystery bug where the display disappears. That would happen when I get a mouse moved event with the middle button down before I got a middle button down event; orig.proj{Right,Up} were invalid.

Hide the sweep and helical sweep for now. Exact surfaces feel more and more necessary, and that complicates those.

Don't enable GL_POLYGON_SMOOTH. That looks awful on my other laptop, for some graphics card reason.
