and curve.cpp and surface.cpp contain the rest.
Also get rid of the meshError stuff; will just use the nakedEdges
mechanism for that. And I won't run the interference test
continuously, have added a menu item for that.

triangle join. And add controls to show and hide the solid model
edges (independently of the shaded mesh), and to suppress the
shaded triangles from SVG/EPS output.
[git-p4: depot-paths = "//depot/solvespace/": change = 1932]
export. So I calculate lighting for each triangle in the mesh, make
a BSP, and then traverse it in-order and output those as SVG or
EPS. And I test edges against the mesh, removing those portions of
the edge that overlap a triangle in front of them (using the
kd-tree to accelerate).
[git-p4: depot-paths = "//depot/solvespace/": change = 1931]
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.
So before going further, I seem to need my own triangulation code.
I have not had great luck in the past, but I can't live without it
now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1899]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1887]
or lines against lines. The constraints get rather screwed up
afterwards, of course.
So make arcs with the endpoints coincident into circles, instead
of nothings; since the first split of a circle produces that.
And don't warn after deleting just point-coincident or horiz/vert
constraints as a dependency; that's just a nuisance, because it
happens too often.
[git-p4: depot-paths = "//depot/solvespace/": change = 1884]
tables in the code, which I have written in perl and am checking
in.
Also get WM_MOUSELEAVE events from win32, so that I can de-hover
everything when the mouse leaves the graphics window. And fix one
of the icons, which was 23x24 instead of 24x24.
[git-p4: depot-paths = "//depot/solvespace/": change = 1883]
auto-showing when a solve fails. And accept expressions, not just

just applies an offset to the DXF before exporting. Useful enough
to be worth the ugliness, though.
This is the stupid routines from SketchFlat, slightly reworked.

but the mesh doesn't get combined. That effectively hides it, good
for looking inside and such.
[git-p4: depot-paths = "//depot/solvespace/": change = 1860]
linear segments to generate, irrespective of the chord tolerance.
That used to be hard-coded, and it needs to be small enough to
avoid lags while working interactively, but I also need to export
fine geometry.
[git-p4: depot-paths = "//depot/solvespace/": change = 1857]
some magic numbers. This would be trivial to break, but still more
difficult than patching the binary to skip the check...

And don't regenerate the emphasized edges unless we have to;
specifically, don't do it when the only dirty group is the
drawing group.
[git-p4: depot-paths = "//depot/solvespace/": change = 1849]
These are just a convenience, since it would be possible to get the
same result by drawing a construction line.
[git-p4: depot-paths = "//depot/solvespace/": change = 1836]
And fix a bug; wasn't asking the user whether to save before
abandoning file when a new file was opened recent.
[git-p4: depot-paths = "//depot/solvespace/": change = 1830]
based on a chord tolerance. And rewrite the pwl circles to work
against a chord tolerance too (which they really were doing before,
but in funny units).
Also make "assemble" combine type do a union after interference
checking; was previously just copying, which meant that coplanar
faces could break subsequent operations.
And make right-clicking effectively toggle shift key, instead of
forcing it on; so you can pan or rotate with either right or middle
button.
[git-p4: depot-paths = "//depot/solvespace/": change = 1829]
all coordinates are divided by that number as we export.
And add functions to store a float in the registry. I'm using those
for the scale factor, and also to replace the crazy scaled integers
that I was using for light positions etc. before.
[git-p4: depot-paths = "//depot/solvespace/": change = 1824]
specify the plane from which we want to grab the triangles. Shared
edges are then removed with the same code used to check for
watertight meshes, and the remaining edges are assembled into
polygons.
[git-p4: depot-paths = "//depot/solvespace/": change = 1823]
introduced by the bsp routines. It's usually, though not always,
possible to generate a watertight mesh. The occasions where it's
not look ugly, floating point issues, no quick fix.
And use those to generate a list of edges where two different faces
meet, which I can emphasize for cosmetic reasons (and some UI to
specify whether to do that, and with what color).
And make the right mouse button rotate the model, since that was
previously doing nothing.

The TTF text is its own entity, and that entity includes the
font file basename and the text. That's an extra 128 bytes in the
entity, which is around a 50% increase, kind of a shame. It was
simple, though.

The pitch (both axial and radial) gets specified by typing a

separate groups. The section is swept normal to the trajectory,
producing a mesh. I'm doing the triangles only now, not copying
over any entities.
Also fix a bug in the PNG export; rows are 4-aligned, so that was
breaking when the width of the image wasn't divisible by four. Also
fix a bug in lathes, where it generated overlapping triangles for
one segment.
And change the groups to record both "this mesh", the contribution
due to the extrude/lathe/whatever, and the "running mesh", that we
get after applying the requested Boolean op between "this mesh" and
the previous group's "running mesh". I'll use that to make step and
repeats step the mesh too.

GW.showPoints is false, and zoom to fit before regenerating on file
open, because then we're at the right zoom level (and will use the
right pwl tolerance).

up remap list search with a hash table, other stuff.

just the mesh, no derived entities (but I suppose that I could turn
all points into circles).
And fix some bugs where equations didn't get unique IDs, and make
it possible to lock on to the group's workplane automatically, if
you press W while free in 3d with no workplane selected.
[git-p4: depot-paths = "//depot/solvespace/": change = 1780]
and requests to a separate list. It's messy, because I have to make
a deep copy (e.g. of the remap list for the groups, or Expr *
stuff) of some things. Others (e.g. the polygon or mesh) will be
regenerated, so they should be discarded, but they must not get
double-freed.
In any case, works superficially. And fix a few memory leaks
unrelated to this, and remove some dead code.
[git-p4: depot-paths = "//depot/solvespace/": change = 1775]
becomes dirty when the user makes a change, and only the dirty
groups get solved. That's a huge effective speedup.
Also add delete function for groups. That has an interesting issue;
it actually ends up recursing on GenerateAll(), since GenerateAll()
calls ClearSuper(), ClearSuper() might need to recreate a group (if
all the groups were deleted), and that would activate the group,
which calls GenerateAll. The right solution is probably a deferred
execution mechanism, where you can schedule something to happen
before we go idle, but not do it right now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1771]
in one place. And remove the ability to disable the solver, since
that's unlikely to be anything but confusing (and in any case, was
badly implemented). This is in preparation for selective solving,
of only the dirty groups.
[git-p4: depot-paths = "//depot/solvespace/": change = 1769]
solid red or yellow. And add user interface to `hide' the faces
(i.e., to make them unselectable), defaulting to hidden in
everything except extrudes or imports.
[git-p4: depot-paths = "//depot/solvespace/": change = 1768]
more starting work on the selectable faces, and fiddling in an
attempt to remove dependencies when stuff gets deleted.

csg ops; so the union of a red part and a blue part has both red
and blue faces. And some user interface to pick the color in the
text window.
The metadata also include a face, which will be an entity; I can
use that to constrain against. But none of that is yet implemented.

nicely. And to do that, I've added the user interface to show an
edit control in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1749]
so e.g. a new extrude starts in free space, which is likely what
you want. And default to an in-workplane group, and tweak the
display of workplanes.
