Jonathan Westhues bd0e97bad0 Now I can suppress an imported part; so the entities still show up,
but the mesh doesn't get combined. That effectively hides it, good
for looking inside and such.

Jonathan Westhues 22b78e4427 Assemble the group polygon ourselves when exporting a DXF; that
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.

Jonathan Westhues 7b7d2f92e9 Add code to evaluate the volume of a mesh, thanks to the divergence
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.

Jonathan Westhues 304c8f8be9 Add equal-angle constraints. These are implemented by brute force,
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.

Jonathan Westhues 4afc881bf2 Add a command to create an arc that's tangent to two line segments.
This was possible before (by drawing everything explicitly), but
now it's easy.

2008-07-13 18:45:11 -08:00
Jonathan Westhues 88fc69116f Add tangency constraints, for line segments against arcs or cubics.
These are just a convenience, since it would be possible to get the
same result by drawing a construction line.

Jonathan Westhues 7622534b2a Make the piecewise linear stuff for cubics and quadratics adaptive,
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.

2008-07-09 21:26:08 -08:00
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.

2008-07-05 23:56:24 -08:00
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.

2008-07-02 01:21:29 -08:00
Jonathan Westhues 48c5018613 Add symmetric about line constraint. This applies only when locked
in a workplane, since it would otherwise be ambiguous.

2008-07-01 22:59:49 -08:00
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.

2008-06-30 01:09:17 -08:00
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.

2008-06-23 00:25:17 -08:00
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.

[git-p4: depot-paths = "//depot/solvespace/": change = 1802]
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.

2008-06-21 02:18:20 -08:00
Jonathan Westhues 4c6d350cee Add two more exotic constraints: equal point-line distances, and
point-line distance equal to line segment length. These are
available in both normal and projected versions, with fancy display
for all of these.

Jonathan Westhues d391c43bff Now display dimensions (and stuff in the text window) in the
user-selected units, and enter them the same way.

[git-p4: depot-paths = "//depot/solvespace/": change = 1792]
2008-06-14 01:51:25 -08:00
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.

2008-06-14 00:43:38 -08:00
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.

[git-p4: depot-paths = "//depot/solvespace/": change = 1789]
2008-06-12 20:41:27 -08:00
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).

[git-p4: depot-paths = "//depot/solvespace/": change = 1788]
2008-06-12 00:58:58 -08:00
Jonathan Westhues 650e9db150 Add more measurement information about the selection. And remove
menu items for some features that I suppose I won't add, and fix
some bugs.

Jonathan Westhues 8969687904 Bits and pieces; option to not include original in step translates
and rotates, auto-constrain translates in active workplane, speed
up remap list search with a hash table, other stuff.

Jonathan Westhues d471872830 Add reference dimensions, add user-programmable lighting, and add a
configuration screen where all this can be specified.

Jonathan Westhues f2645029b8 Add a second light, and some little fixes, and remove dead code.

2008-06-09 01:03:21 -08:00
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).

2008-06-05 23:50:08 -08:00
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.

2008-06-04 02:22:30 -08:00
Jonathan Westhues 71391e6a55 Add an interference check for assembled parts. That's easy once the
BSP stuff works. The failures are reported with red stripes and no
depth buffering, and in a message in the text window.

Also improve convergence of point-on-line constraints, and don't
write triangles to export files with limited precision, because
that was making the coplanar tests fail.

[git-p4: depot-paths = "//depot/solvespace/": change = 1774]
2008-06-03 22:39:32 -08:00
Jonathan Westhues ea6db67c7d Improve convergence of constraints involving parallel vectors, by
using the initial numerical guess of whichever vector is already
known to choose our projection planes.

And add a mechanism to defer showing the text window or
regenerating, in order to simplify dependencies on valid actives.
Also yes/no/cancel when about to abandon an unsaved file, and a
bugfix when rotating a rot/trans point.

2008-06-03 10:28:41 -08:00
Jonathan Westhues 5bbb27fd8e Now requests don't have names anymore, because that didn't seem
useful. The description string is just the type of request.

2008-06-02 01:41:39 -08:00
Jonathan Westhues 236ee16da6 Consolidate the code that determines whether an entity is visible
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.

2008-06-02 01:31:26 -08:00
Jonathan Westhues a084b32064 Stipple the selected/hovered faces, instead of drawing them in
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]
2008-06-01 21:38:12 -08:00
Jonathan Westhues 6748160026 Add selectable faces, by associating an hEntity with the triangle's
metadata. And add point-on-face constraints to go with that. Still
needs some cleanup for the user interface.

[git-p4: depot-paths = "//depot/solvespace/": change = 1766]
2008-06-01 19:31:37 -08:00
Jonathan Westhues 709b5ad80e Add an axis-angle transformation (rotation about an arbitrary
point), and use that to implement step and repeat rotating.

[git-p4: depot-paths = "//depot/solvespace/": change = 1762]
2008-06-01 00:29:59 -08:00
Jonathan Westhues 2cb4800fbf Start to describe the selected entities in the text window. Also
more starting work on the selectable faces, and fiddling in an
attempt to remove dependencies when stuff gets deleted.

[git-p4: depot-paths = "//depot/solvespace/": change = 1760]
2008-05-31 16:26:41 -08:00
Jonathan Westhues 69eb2273ac Add color. Now each triangle has metadata, which are preserved in
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.

[git-p4: depot-paths = "//depot/solvespace/": change = 1757]
2008-05-29 22:09:41 -08:00
Jonathan Westhues 4bd44bf18a Initial work on the assembly (`import') feature. I can import a
part, including all of its entities and the triangle mesh. These
are transformed by a rotation and translation, and appear in the
sketch; the transformation may be set with constraints.

Jonathan Westhues 010a65894d Now I can rename groups, using that same edit control in the text
window.

2008-05-27 01:52:36 -08:00
Jonathan Westhues 4375c01c51 Add step and repeat translate, with multiple copies; that all works
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]
2008-05-26 22:36:59 -08:00
Jonathan Westhues ecee90965e Change the workplanes a bit. Now the active workplane is per group,
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.

[git-p4: depot-paths = "//depot/solvespace/": change = 1748]
2008-05-26 18:22:20 -08:00
Jonathan Westhues b484c26493 Many user interface additions. Now I report when the solver fails,
and in the case of a singular Jacobian, report which constraints
can be removed to fix it. Also a mechanism to hover and select
entities and constraints from the text window.

[git-p4: depot-paths = "//depot/solvespace/": change = 1746]
2008-05-26 01:56:50 -08:00
Jonathan Westhues 248f74547e Add user interface to specify union/difference for extrudes, and
implement that. Also make solver work only between the first and
last visible group; earlier can just work from previous solve
result, and later don't matter.

There's some issues with the csg code; it will eventually produce
an open mesh, which is very bad. Not sure whether that's a logic
bug, or a numerical issue; still generating absurd triangles pretty
routinely.

2008-05-25 05:11:44 -08:00
Jonathan Westhues e80328279e Rip out the boundary rep csg stuff. I'll redo that with a triangle
mesh approach.

2008-05-20 19:58:14 -08:00
Jonathan Westhues c4e1270e25 Add constructive solid geometry ops. These work to some extent, but
not very well; I'm doing a b-rep, where the boundaries are complex
polygons, and there's too many special cases. I should probably
replace this with a triangle mesh solution.

[git-p4: depot-paths = "//depot/solvespace/": change = 1731]
2008-05-19 01:23:49 -08:00
Jonathan Westhues 30ad41f4a2 Fix a crash; it was possible to attempt to draw in a workplane
that's in a group that solves after the current group. This means
that the constraint/request gets deleted instantly, and stuff like
auto-constraints on the just-created entities blow up. I now check
that the active workplane comes from the active group or one solved
before it.

[git-p4: depot-paths = "//depot/solvespace/": change = 1729]
2008-05-17 15:48:58 -08:00
Jonathan Westhues b480613763 Add angle constraints. I'm doing these differently from SketchFlat,
as a constraint on the direction cosine, rather than driving the
dot product against a rotated vector to zero. The drawing is the
ugly part; to do that for skew lines, I gave up.

Also add a function to clear non-existent items on the selection
after solving, since that could have caused an oops().

[git-p4: depot-paths = "//depot/solvespace/": change = 1727]
2008-05-17 03:15:14 -08:00
Jonathan Westhues 749e2a0149 Add double-sided extrudes, and user interface for that. Also put
the coordinate system (x, y, z normal vectors) in the bottom left
corner of the screen at all times, and hide group-created
workplanes except when that group is active, and activate that
workplane when the group is activated.
