Daniel Richard G 16179f34cd Enabled freeing of (most) allocated memory on program exit
The Valgrind tool can give a full accounting of what memory allocations
have yet to be free()d when the program exits. It is easier to find actual
memory leaks in the code if all non-leaked allocations are elided from that
accounting, which is most easily accomplished by free()ing them.

The "most" qualifier is there because some allocations are difficult/
impossible to free, as they are internal to libraries like OpenGL and Xft.
The best we can hope for is to cover all allocations made by SolveSpace
directly.

Daniel Richard G 42a46e83fa Use system-agnostic return values for SaveFileYesNoCancel()
This function was returning ID{YES,NO,CANCEL}, which are specific to
Windows as return values for MessageBox(). These have been replaced with
SAVE_{YES,NO,CANCEL}, which we define ourselves.

Daniel Richard G 5cca524c62 Changed "static const int" class members into enums
Not only is the enum syntax more compact, it avoids inadvertent link
failures resulting from how C++ treats "static const int" members:

http://stackoverflow.com/questions/5508182/static-const-int-causes-linking-error-undefined-reference

(And for what it's worth, MSVC6 gave silly errors for these members
wherever a non-zero value was assigned.)

Daniel Richard G 66f46b7b67 General compiler warning/error fixes
This addresses a grab bag of compiler grievances relating to C++ syntax,
type, and scope, as observed on Linux with g++ and Solaris with Sun
WorkShop 6.

Daniel Richard G 1b00c8c3ab Use size_t instead of int in the memory allocation routines
size_t is the correct type to use when specifying the memory-size of an
object. That is why sizeof(), strlen() and malloc() all use it.

Daniel Richard G dcc963aa4b Modified Get{BYTE,WORD,DWORD}() to return the respective type
Having e.g. GetWORD() return a WORD rather than int eliminates the need for
a cast when assigning to WORD variables. We use casts only when assigning
to a different (but same-sized) type.

Also, check for EOF explicitly when calling fgetc().

Daniel Richard G 02776ea535 Added const qualifiers
String literals in C++ are implicitly typed as 'const char *', and with
this change, their const-ness is maintained when assigning them to
variables or passing them as arguments. This significantly cuts down the
number of warnings generated by the compiler.

Jonathan Westhues 3dc21ec8dd Make oops() calls exit instead of entering debugger by default,
since the latter looks worse if it happens to someone else.

Jonathan Westhues cc3b17f60e Make the number of digits after the decimal point (for dimensions,
as they are displayed on the drawing, and for many other places) a
user-configurable parameter.

Also reshuffle some options in the configuration screen, to put all
the stuff relating to exports together.

Jonathan Westhues 439e4d3124 Add a color picker, with a fancy HSV (actually, a modified version
of that, where you can pick the hue and blackness, and then the
whiteness) color picker and some swatches.

This is used in three places now: the special colors in the config
screen, the background color, and the style colors.

Jonathan Westhues 824cc00915 Put wrappers around the functions to show and hide the edit control
in the text window. This means that I can move the conversion from
half-row and column to (x, y) into the platform-independent code,
and that I'll be ready to add my color picker.

Jonathan Westhues fe2ea5d5e1 Improve the non-parametric rounding. It now works on both lines and
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.

Jonathan Westhues 01ecb986f4 Instead of a "force parallel projection" menu item that's on by
default, let's do a "use perspective projection" item that's off by
default. Same meaning, but less confusion.

Jonathan Westhues 0246add3e9 Replace ugly text links to hide/show things with icons. So add code
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.

2010-05-02 21:04:42 -08:00
Jonathan Westhues c4b442f92f Initial work to move text window guts into platform-independent
code. This is now drawn using gl, and the bitmap font (both there
and in the graphics window) is drawn from a texture from a static
table, not from the Win32 functions, since that's ~1000x faster.

So this adds a tool to generate that table. With luck that will
also fix my font issues under WINE, which won't have to render the
TTF itself.

Still needs some cleanup, and to make all the cosmetic improvements
that I want.

File -> New or File -> Open, I freed the Group structures
themselves, but none of their children.

consistently across multiple versionf of Windows, and perhaps not
be immediately ignored by the user.

Jonathan Westhues 342729d9a4 Indicate the just-exported origin and basis x and y vectors after
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).

2010-01-13 21:24:32 -08:00
Jonathan Westhues a0a7feda89 Add G Code export to SolveSpace, similar to SketchFlat. This
requires user interface to specify the depth, number of passes,
feed, and plunge feed, unfortunately.

2010-01-13 20:47:17 -08:00
Jonathan Westhues ba8ac7dcd3 Add a screen to edit the view parameters; scale, translation,
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.

2010-01-03 16:35:28 -08:00
Jonathan Westhues b974a4adeb A big nasty change, originally just to add paste transformed. So it
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.

2009-12-15 04:26:22 -08:00
Jonathan Westhues 9723f4e44f Add support for a clipboard, with cut, copy, and paste. This works
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]
2009-12-04 00:08:41 -08:00
Jonathan Westhues d74b1e7ece Add ability to set a background image. I import a png with libpng,
load it as a texture, and show it instead of a flat-color
background. Includes user interface to specify scale and
translation of image, but the rotation is always aligned to the
view.

[git-p4: depot-paths = "//depot/solvespace/": change = 2071]
2009-11-07 17:11:38 -08:00
Jonathan Westhues b9ab62ab3f Remove arbitrary limits on the selection size, and permit more than
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.

2009-11-03 10:54:49 -08:00
Jonathan Westhues 3515748334 Make the EPS, PDF, and SVG targets output filled contours. This
also means that closed contours will get output as a single path
now, vs. one open path per Bezier segment before.

I've simplified the 2d/3d wireframe export targets somewhat; they
now support only Beziers, without an additional special case for
line segments. The performance penalty for that should not be worth
caring about, since that's infrequent.

And fix a memory leak in FindOuterFacesFrom(), fix ugly output of
filled triangles in PDF (because the line join style did bad things
on long skinny triangles), fix non-zero Z coordinates for exported
views or sections in DXF or STEP.

2009-10-30 02:38:34 -08:00
Jonathan Westhues 2ca5334bdf Add interpolating splines: both periodic splines (that form a
loop), and open-ended splines, with their tangents specified at
their endpoints.

Also change constraint solver matrix size to 1024, on the theory
that a power of two will generate better array indexing, and
replace fabs() with my own function that for some reason is
faster.

Jonathan Westhues f6bb680978 Add Wavefront OBJ support, to supplement the existing STL mesh
export. That doesn't seem very useful, but it's only a few dozen
lines of code.

Jonathan Westhues 83bbc004dc Add 3d wireframe export, in DXF or STEP format. This uses most of
the same plumbing as the 2d vector output.

Also fix piecewise linear tolerance when the export scale factor is
not equal to one; have to scale the chord tol along with that.

Jonathan Westhues 33dfff2a78 Add option to disable the "not closed contour" warnings and such,
instead of tying that to whether the shaded model is shown. And
rewrite all URLs to solvespace.com, not www.solvespace.com, and get
rid of the nag screen that I just added because opening the website
with ShellExecute seems to freeze a bit on startup.

Jonathan Westhues db565438e3 Add text angle for styles. Add ability to quickly change between
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.

Jonathan Westhues 9416faca88 Add a context menu, with a grab bag of options. That will need some
refinement later, but it does not affect file formats so it's not
very critical.

Jonathan Westhues 9b8f32dad7 Now actually export the line styles, for PDF, EPS, and SVG file
formats, with the proper color and width. This may need a bit of
cleanup for stuff like the hidden line removal, which currently
loses the style.

Also fix a bug in the test for arcs of a circle. A second-order
Bezier with collinear control points really is an arc, but it's an
arc with infinite radius so stuff tends to blow up. So return false
for that one.

2009-09-21 21:46:30 -08:00
Jonathan Westhues 517c5edbfa Add user interface to modify styles: change the color, line width,
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.

Jonathan Westhues ce99217bbb Move colors and line widths for almost everything to the styles
mechanism. This gets filled in from some defaults, and stored in
the registry. The default styles do not get saved in the file, but
user-created styles (which aren't supported yet) do.

2009-09-16 23:32:36 -08:00
Jonathan Westhues e989c86a38 Add ability to set export canvas size (paper size for PDF, bbox
size for EPS, etc.). This can either be fixed, with a given width
and height and offset, or automatic, by the left right bottom top
margins.

And draw nicer dimensions for length, with arrows and more
extension lines. Add code to trim those lines against the
(rectangular, axis-aligned) box that contains the actual number,
and use that (instead of the elliptical interpolation, which was
only approximately right) for diameter dimensions too.

2009-09-03 00:13:09 -08:00
Jonathan Westhues 66c93aab73 Add a mechanism to record the lines drawn when we display a
constraint, so that we can export that too. This includes the lines
for the vector font.

A little ugly; it needs some kind of line style (color or width) to
distinguish those lines from the real geometry in the exported
file.

Jonathan Westhues 603f47692e When exporting STEP, identify the outer contours, and group them
and their holes into their own advanced faces. So a single surface
with multiple outer contours generates multiple advanced faces.

Also turn the default chord tol down to 1.5 pixels, seems more
likely to make the exact surface Booleans work.

2009-06-08 08:21:33 -08:00
Jonathan Westhues 9455037e49 Add beginnings of STEP export, which weren't as horrible as I had
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.

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

export sections of a mesh.
