Jonathan Westhues ddbd0ff77b Add ability to represent our surfaces as either a shell or a mesh,
according to the user's preference. I templated the housekeeping
stuff for Boolean operations and step and repeat, so it's
relatively clean.

Still need to add the stuff to make a mesh vertex-to-vertex, and to
export sections of a mesh.

Jonathan Westhues ddf9364257 Add a separate display mesh and edge list; so if we're working with
a mesh than that's a copy, and if we're working with a shell then
it's the shell's triangulation.

Jonathan Westhues a4dc518a89 A monster change; move the parameter, entity, group, and constraint
tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.

Jonathan Westhues 1a845c3432 Add hidden line and surface removal, and vector shaded surface
export. So I calculate lighting for each triangle in the mesh, make
a BSP, and then traverse it in-order and output those as SVG or
EPS. And I test edges against the mesh, removing those portions of
the edge that overlap a triangle in front of them (using the
kd-tree to accelerate).

Jonathan Westhues acadc0a918 Many changes:
* 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.

Jonathan Westhues adc910185c Add plane-plane intersection as a special case (to generate the
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.

Jonathan Westhues 2e4ec6dd04 Add sin and cos to the expression entry (for dimensions etc.), with
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.

Jonathan Westhues 37795d24ba Don't let the user create workplanes locked in another workplane;
that is almost surely a mistake.

Jonathan Westhues 0f228fc0fb Add a toolbar. This requires a tool to convert my PNG icons to
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.

Jonathan Westhues 23a4ce3697 Auto-show the text window when stepping a dimension, in addition to
auto-showing when a solve fails. And accept expressions, not just
numbers, for that new dimension value.

Jonathan Westhues fe77e7cf7e Don't enable GL_POLYGON_SMOOTH. That looks awful on my other
laptop, for some graphics card reason.

2008-08-14 23:37:19 -08:00
Jonathan Westhues 96f5663d6e Add a configuration option to hide the back faces; that gets rid of
stray red pixels sometimes, if the mesh is leaky or the graphics
card isn't perfect.

Jonathan Westhues 8fe910da4d Add feature to trace a point; so I can show the path that a
linkage traces out, and export the coordinates.

Jonathan Westhues d2c4d2cdb7 Swap meaning of middle and right mouse buttons (now center means
drag, right means pan), and extend reference manual.

2008-07-18 05:31:22 -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 7cf0deb9f4 Reassign the keyboard shortcuts so that the constraints don't all
start with Shift, since that's hard to type.

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.

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 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 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 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.

Jonathan Westhues e67ea9ca0f Add perspective, by a user-specified factor. So I have to apply
that perspective in the gl matrices, and also everywhere that I
check mouse pointer positions against the model, and for the zoom
to fit.

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 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).
