Jonathan Westhues dd23aa11a2 Make rotations default to 360/n degrees (uniform about a circle)
if no constraints set the rotation.

Jonathan Westhues 9136d86bff Split solvespace.cpp; leave the file menu and general-purpose stuff
where it was, move the export (DXF, PNG, STL) stuff to export.cpp,
and move the regen/solve stuff to generate.cpp.

Jonathan Westhues 72d188619d Add a scale factor when exporting; the user specifies a number, and
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.

Jonathan Westhues b2f2f90a27 Add DXF export. The complexity comes from all the different ways to
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.

Jonathan Westhues b4a9ac993c Add export of the mesh as an STL file. That's trivial.

Jonathan Westhues cad77c9c47 Add routines to remove T intersections from the mesh, which are
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.

Jonathan Westhues d4d5ab578d Add a special case when raising quaternions almost equal to
(+/-1, 0, 0, 0) to some power; that was failing if the magnitude of
w was slightly greater than 1, so that acos() returned NaN.

Jonathan Westhues fd4abd5519 Add a perpendicular constraint; identical to constraining a ninety
degree angle, but shows with a right angle symbol instead of a
numerical angle you can edit.

questionable tolerance on the pivot while row reducing.

Jonathan Westhues 48c5018613 Add symmetric about line constraint. This applies only when locked
in a workplane, since it would otherwise be ambiguous.

Jonathan Westhues 273339d5c4 Add TrueType font support to SolveSpace. This uses a modified
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.

Jonathan Westhues a31782e1ea If any equations are soluble in a single variable, then handle them
separately, even before doing the rank test. In some cases, that's
a huge speedup.

Jonathan Westhues a47a77c37c Back to opengl's tesselator for triangulation. I'll spend more time
writing mine later.

Jonathan Westhues 9b008ad1cd Check in a broken triangulation code (by stupid ear clipping),
which I will shortly revert. gl does a much better job, and I'll
have to spend more time to get something reasonable.

Jonathan Westhues 12942a74cf Add logic to remember imported files' relative filenames, and use
that to try to find them if we can't find them by absolute path.
This is intended to make everything still work if you copy an
entire directory tree of files that import each other.

Also add a mechanism to not paint the scene if we're not sure it's
consistent; otherwise got some crashes on startup. And disable both
text and graphic window when displaying a modal dialog, wasn't
doing that always.

Jonathan Westhues 3ddd1703b1 Add helical sweeps. These aren't as parametric as I would have
liked, but my more parametric attempts were very difficult to use.
The pitch (both axial and radial) gets specified by typing a
distance in a textbox.

Jonathan Westhues fe75efc6aa Make the point-on-circle constraints work on the infinite cylinder,
not the sphere; that's more logical behaviour out of plane.

Jonathan Westhues a5189f7f1a Make step and repeats step the mesh, as well as the entities. This
requires new entitiy types for the faces, by translation or by
axis-angle rotation.

2008-06-21 14:49:57 -08:00
Jonathan Westhues 5a22982e05 Add sweeps. The user specifies a trajectory and a section, in two
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.

Jonathan Westhues 89bb81b35c Force the numerical guess for a normal to be exactly correct when a
same orientation constraint is applied; this makes convergence
easy. And don't hover faces or constraints while dragging
something.

for all of these.

Jonathan Westhues 28e3f0abab Don't keep a dimension or group's user-entered numerical value as
an Expr *, since that complicates multiple units and also memory
management. Now it's just a double.

Jonathan Westhues 1674443ab2 Fix stupidity in the rotate ops; first of all it was saving the
axis of rotation numerically, so that the associative thing breaks,
and then it also wasn't saving the point on the axis in the file,
so that snapped back to (0, 0, 0) on reload. Now it goes off the
hEntity for a point on the axis and a vector in its direction.

Jonathan Westhues b284baffce Treatment of numerical faces was screwy, exporting stuff in numXXX.
So fix that, and now I can simplify what's exported for an entity.

And add an extra measurement (face-face distance/angle), and some
other little stuff.

Jonathan Westhues 9bba9425be Add a special constraint type for comments; no equations, just
user-visible text. And make points hoverable/selectable even when
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).

Jonathan Westhues 8498a99588 Add preliminary lathe (solid of revolution) support. I'm generating
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.

Jonathan Westhues ab44c24cfc Major speedups, mostly by playing nicer with OpenGL; batch things
up more. Also change from stupid linear search lists to sorted
binary search lists, remove a stupid bug where I double-generated
entities, and don't do the triple drawing of entities (since
offsets on the Z buffer were doing the same job already).

Jonathan Westhues 48612bde3d Add undo/redo. This saves the param guesses, constraints, groups,
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.
