circles, using a numerical method. And the user can specify a
radius, instead of letting us choose automatically, and specify
whether the original lines should be kept and made construction, or
deleted.

possible. This replaces all of the color-coded links, that I liked
but that were nonstandard.
Also rip out the old sweep and helical sweep UI; that was disabled,
but the code was still present.
And fix dependencies in makefile, since textwin.cpp depends on the
icons now.
[git-p4: depot-paths = "//depot/solvespace/": change = 2139]
default, let's do a "use perspective projection" item that's off by
default. Same meaning, but less confusion.
[git-p4: depot-paths = "//depot/solvespace/": change = 2132]
to draw those, and hit test with the mouse, and display tool tips
when the user hovers with the mouse. Also, underline links only
when they're hovered, and not otherwise.
And add a separate menu option to align the view to the active
workplane, vs. activating the active group's workplane, and
remap the bottom two graphics window toolbar icons to that and
"nearest iso view" instead of draw in 2d/3d, since people tended
to click on those without understanding and cause trouble.
And by default, we force a parallel projection; so the factory
default camera tangent is now 0.3, not 0.
[git-p4: depot-paths = "//depot/solvespace/": change = 2131]
easy and useful. Also make the volume measurement use Message(),
and not a separate text window screen.
And make Edit -> Unselect All (Esc) clear the marks drawn to
indicate free parameters, since it clears all the other temporary
stuff drawn in the graphics window.
[git-p4: depot-paths = "//depot/solvespace/": change = 2121]
exporting our view to any file that doesn't have a canvas size (and
therefore doesn't get everything shifted to fit with the requested
margins around it in the canvas).
[git-p4: depot-paths = "//depot/solvespace/": change = 2107]
rotation. Also clean up the handling of units, by putting the
conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error
message.
[git-p4: depot-paths = "//depot/solvespace/": change = 2093]
left-clicking always selects, and there's a special context menu
item to deselect. Also streamline the right-click behavior by
making that select the hovered item, and making all the context
menu items work on the selection.
[git-p4: depot-paths = "//depot/solvespace/": change = 2091]
selected entities, but cleared after dragging an unselected entity.
Marquee selection is select-only (not toggle), and "Select All"
replaces "Invert Selection". Left-click on nothing will clear the
selection.
Also add context menu entries for cut, copy, and paste.
[git-p4: depot-paths = "//depot/solvespace/": change = 2089]
does that, and adds a scale factor to that transformation (instead
of just mirroring, as before), but also:
* Replace the "import mirrored" mechanism with a scale factor,
which if negative corresponds to a reflection as well.
* Fix self-intersection checker to report a meaningful point
when edges are collinear.
* Don't blow an assertion on some types of invalid file;
instead provide a nice error message to the user.
* Clear the naked edges before each regen.
* Don't create zero-length line segments by snapping a line
segment's end to its beginning.
[git-p4: depot-paths = "//depot/solvespace/": change = 2086]
only in a workplane; but this means that plane sketches are
conveniently transformed from one plane to another.
Also tweak snap to grid to ignore unsnappable entities instead of
triggering an error, and to remove arbitrary limit on the number of
entities / comments that will be snapped.
[git-p4: depot-paths = "//depot/solvespace/": change = 2084]
because it can't be C2 continuous after splitting (since I'm
doing uniform splines only, and the parametrization changes). So
just knock everything down to cubic Beziers.
Also draw lines to indicate angle and origin when Ctrl+dragging to
rotate in plane of screen.
[git-p4: depot-paths = "//depot/solvespace/": change = 2075]
under the just-deselected coincident point when I'm working on
batches, which really could have selected that underneath point.
And always pwl curves to at least two line segments (and likewise
retain at least one intermediate point when removing short edges),
to avoid confusion when holes end up square.
[git-p4: depot-paths = "//depot/solvespace/": change = 2070]
work on hidden entities. Also fix bug where undo state wasn't saved
before toggling construction.
[git-p4: depot-paths = "//depot/solvespace/": change = 2067]
one point to be dragged simultaneously. So now a dragged point
drags all the selected points and entities, and a dragged entity
drags its points (except for circles, which drag the radius).
This means that the number of forced points for the solver must now
be unlimited, and it is.
Also add commands to invert the selection within the active group,
and to select an edge chain starting from the current selection.
And redo the context menus a bit; still not great, but less
cluttered and more systematic.
[git-p4: depot-paths = "//depot/solvespace/": change = 2064]
to assemble Beziers into outer and inner loops, and find those
loops made up of entities with filled styles. The open paths are
maintained in a separate list, and we assemble as many closed paths
as possible even when open paths exist.
This changes many things. The coplanar check is now performed on
the Beziers, not the resulting polygon. The way that the polygon is
used to determine loop directions is also modified.
Also fix the mouse behavior when dragging a point: drop it when the
mouse is released, even if it is released outside the window, but
don't drop it if the pointer is dragged out of and then back into
our window.
Also special-case SSurface::ClosestPointTo() for planes, for speed.
[git-p4: depot-paths = "//depot/solvespace/": change = 2058]
perspective and parallel projections. Add a snap grid, for points
and for text comments. Draw text comments in the plane of their
workplane if they have one, otherwise always facing forward.
And fix a few nasty bugs: the possibility of an extremely long
animation onto a workplane, accidental use of the wrong style line
width for constraints, misplaced text box in style screen for
default styles, other little stuff.
[git-p4: depot-paths = "//depot/solvespace/": change = 2037]
Constraint::COMMENTs), including line width and color, and text
height and origin location.
[git-p4: depot-paths = "//depot/solvespace/": change = 2033]
line width units, on-screen and export visibility. So now we can
use that to modify the default styles, or to create custom styles.
Also add code to draw fat lines, with round endcaps, since gl
doesn't do that.
Next we need some user interface to assign styles to entities, and
to make all the export file formats support the style attributes.
[git-p4: depot-paths = "//depot/solvespace/": change = 2029]
(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]
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]
separate polygon of coincident (with same or opposite normal)
faces; I instead test all the edges against the other shell, and
have extended the classify-against-shell stuff to handle those
cases.
And the normals are now perturbed a bit numerically, to either side
of the edge, to distinguish tangency from a coincident surface.
This seems to work fairly well, although things still tend to fail
when the piecewise linear tolerance is too coarse.
[git-p4: depot-paths = "//depot/solvespace/": change = 1964]
can show edges for both meshes and shells, and export them and
hidden line remove and all the usual stuff.
And fix the zoom to fit on startup, so that it considers hidden
entities too. That avoids the problem where things get generated at
stupid chord tolerance because no entities were visible and the
mesh of course did not yet exist.
[git-p4: depot-paths = "//depot/solvespace/": change = 1961]
a mesh than that's a copy, and if we're working with a shell then
it's the shell's triangulation.
[git-p4: depot-paths = "//depot/solvespace/": change = 1957]
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]
our specified section plane; we then split them according to the
start and endpoints of each STrimBy, using de Castejau's algorithm.
These sections get projected (possibly in perspective, which I do
correctly) into 2d and exported.
Except, for now they just get pwl'd in the export files. That's the
fallback, since it works for any file format. But that's the place
to add special cases for circles etc., or to export them exactly.
DXF supports the latter, but very painfully since I would need to
write a later-versioned file, which requires thousands of lines of
baggage. I'll probably stick with arcs.
[git-p4: depot-paths = "//depot/solvespace/": change = 1936]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1934]
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]
* Rewrite surface handles in curves, so that Booleans beyond
the first don't screw up.
* If an intersection curve is identical to an existing curve
(as happens when faces are coincident), take the piecewise
linearization of the existing curve; this stops us from
screwing up when different shells are pwl'd at different
chord tols.
* Hook up the plane faces again.
* Remove coincident (parallel or anti-parallel) edges from the
coincident-face edge lists when doing Booleans; those may
happen if two faces are coincident with ours.
* Miscellaneous bugfixes.
It doesn't seem to screw up very much now, although tangent edges
(and insufficient pwl resolution) may still cause problems.
[git-p4: depot-paths = "//depot/solvespace/": change = 1929]
the same precedence as sqrt. Add the code to find naked edges, and
draw them highlighted on the model. And make the direction of trim
curves consistent, always ccw with normal toward viewer; so there's
no need to fix the directions before triangulating.
[git-p4: depot-paths = "//depot/solvespace/": change = 1903]
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

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