the registry. The default styles do not get saved in the file, but
user-created styles (which aren't supported yet) do.

surface's domain of u, v in [0, 1]. Cache the starting guess when
projecting a point into a ratpoly surface, to avoid brute force
searching for a good one every time. Split edges even if they
aren't quite inside the trim curve, since the trim boundaries are
pwl, not exact; unnecessary splits won't hurt, but failure to split
when necessary will. Make the triangulation code use a better (but
not perfect) epsilon, to avoid "can't find ear" failures on very
fine meshes.
And turn on compiler optimization! I had somehow forgotten about
that, and it's a ~2x improvement.
[git-p4: depot-paths = "//depot/solvespace/": change = 2026]
(in my case, a SpaceNavigator). I can transform the view of the
part, or transform a part in an assembly.
Also fix up mouse wheel input, so that it works even if it comes in
chunks of less than 120 units.
[git-p4: depot-paths = "//depot/solvespace/": change = 2019]
steps in thisShell or thisMesh, and then let the Boolean proceed as
usual. If everything works, then this is equivalent. And it's less
code, and it makes stuff like stepping the step and repeat work.
Also begin to work on line/entity/constraint styles, but no real
work yet.
[git-p4: depot-paths = "//depot/solvespace/": change = 2018]
a method that works on the piecewise linear segments, and then
refines any intersections that it finds by Newton's method. So now
I support cubics too, and circle-circle intersections, and the code
is much simpler.

chain. That's much faster than going edge by edge.

feared. Though I don't have rational surfaces or curves going yet,
and I don't have the stuff to handle holes or multiple outer
contours in a single surface.
[git-p4: depot-paths = "//depot/solvespace/": change = 1974]
of revolution, and put them in the same form as if they had been
draw by an extrusion (so that we can use all the same special case
intersection curves).
And add code to merge coincident faces into one. That turns out to
be more than a cosmetic/efficiency thing, since edge splitting
fails at the join between two coincident faces.
[git-p4: depot-paths = "//depot/solvespace/": change = 1965]

things, but this is more or less as it should be.

tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.
[git-p4: depot-paths = "//depot/solvespace/": change = 1942]
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.

trimmed line), and plane-line intersection. Terminate the Bezier
surface subdivision on a chord tolerance, and that seems okay now.
And print info about the graphics adapter in the text window, could
be useful.
Also have a cylinder-detection routine that works; should special
case those surfaces in closed form since they are common, but not
doing it yet.
[git-p4: depot-paths = "//depot/solvespace/": change = 1928]
Add stubs for functions to perform Booleans, and get rid of mesh
stuff, including the kd tree accelerated snap to vertex (which
should not be required if the shell triangulation performs as it
should).
Also check that a sketch is not self-intersecting before extruding
it or whatever. This is dead slow, needs n*log(n) implementation.
[git-p4: depot-paths = "//depot/solvespace/": change = 1902]
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]
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.

equations from the constraints.

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]
some magic numbers. This would be trivial to break, but still more
difficult than patching the binary to skip the check...

version of the code from SketchFlat, with all arbitrary limits
removed.
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1814]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1801]
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]
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.

the constraint is left behind; or the point that's the origin for a
drawing group in plane gets deleted), then deleted the dependencies
too.

to work from a table somehow. Move the quaternion stuff into its

that for the values of the dimensions, for example.

for cosmetics, and start to add the symbolic expression code.

I think, before proceeding.

that's slow. Use classes instead of structs for everything; I don't
understand the template handling for structs. And implement the

to rough in some data structures to hold the sketch. No real work

constraint solver drawing. I've started work on the user inteface,
which will be based around two windows: one with the graphical

line, no other work.
