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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1866]
applies to whichever is closer to original position, and angle
constraint, if the two vectors are lines that share an endpoint,
applies to vectors out from that shared point.
[git-p4: depot-paths = "//depot/solvespace/": change = 1863]
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]
in the numerical code.
And clean some other stuff, in particular simplifying whenever I
have to take the maximum (or minimum) of three quantities.
[git-p4: depot-paths = "//depot/solvespace/": change = 1855]
lets us export open curves, if the user drew them that way.
Also increase the limits on how many pwls we will generate for a
single curve.
[git-p4: depot-paths = "//depot/solvespace/": change = 1854]
some magic numbers. This would be trivial to break, but still more
difficult than patching the binary to skip the check...
[git-p4: depot-paths = "//depot/solvespace/": change = 1853]
it did nothing when GenerateAll got called with an explicit range
(vs. with no args, to run on the dirty groups), so the emphasized
edges ended up out of date. I think this is better.
Also check in latest updates to manual.
[git-p4: depot-paths = "//depot/solvespace/": change = 1852]
than sorting by area. I had hoped that would help with normal
accuracy, but I don't think it helped much, and it sometimes became
very slow.
[git-p4: depot-paths = "//depot/solvespace/": change = 1850]
theorem; it's evaluated as a surface integral over each triangle.
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]
as the difference between the cosines of the two angles. All of the
angle stuff generates huge expressions (Expr *), but doesn't seem
noticeably slow.
[git-p4: depot-paths = "//depot/solvespace/": change = 1847]
on the number of pieces that we know how to reassemble is even
stupider. Now dynamically allocated.
[git-p4: depot-paths = "//depot/solvespace/": change = 1837]
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]
groups, rename "drawing" groups to "sketch" groups, and keep
assembling even after finding an open curve.
[git-p4: depot-paths = "//depot/solvespace/": change = 1835]
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]
could hurt, but still make offsets work as if it's a 16 bit buffer,
since I don't seem to actually get 24 bits.
[git-p4: depot-paths = "//depot/solvespace/": change = 1828]
where it was, move the export (DXF, PNG, STL) stuff to export.cpp,
and move the regen/solve stuff to generate.cpp.
[git-p4: depot-paths = "//depot/solvespace/": change = 1825]
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.
