Grid fitting is performed only on glyph boundaries, since glyphs
include curves converted to pwl, which would be mangled by per-point
grid fitting.
Grid fitting is only performed when the plane in which text is
laid out is parallel to the viewing plane.
Grid fitting is only performed when rendering for display; there
are no devices with dpi low enough for grid fitting to become
profitable, and in any case we cannot predict what the dpi would
be anyway.
First, a larger origin offset is applied in ssglWriteText. This moves
the text so that it doesn't overlap the workplane boundary.
Second, a different offset is applied in ssglWriteTextRefCenter.
After this, the middle stroke of "E" is vertically aligned with
the reference point, and the overall label is horizontally aligned
with the reference point more precisely.
Before this commit, the graphics window edit control always had
a width of 30 average character widths.
After this commit, the edit control has a width of 5 average
character widths (for numeric constraints) or 30 average character
widths (for comment constraints), or just enough to display
the entire value being edited, whichever is greater.
This makes the edit control overlap the sketch less in case of
editing numeric constraints (since in most cases, the numbers being
edited are short), and removes annoying scrolling in case of editing
long comments.
Before this commit, the position of the edit box was adjusted
by trial and error, as far as I can tell. This commit changes
the positioning machinery for edit controls as follows:
The coordinates passed to ShowTextEditControl/ShowGraphicsEditControl
now denote: X the left bound, and Y the baseline.
The font height passed to ShowGraphicsEditControl denotes
the absolute font height in pixels, i.e. ascent plus descent.
Platform-dependent code uses these coordinates, the font metrics
for the font appropriate for the platform, and the knowledge of
the decorations drawn around the text by the native edit control
to position the edit control in a way that overlays the text inside
the edit control with the rendered text.
On OS X, GNU Unifont (of height 16) has metrics identical to
Monaco (of height 15) and so as an exception, the edit control
is nudged slightly for a pixel-perfect fit.
Also, since the built-in vector font is proportional, this commit
also switches the edit control font to proportional when editing
constraints.
Before this commit, solids in the viewport were rendered with
"emphasized edges", with the intention to highlight selectable faces.
However, selectable faces are already surrounded by entities, and
so rendering emphasized edges adds little value.
After this commit, solids in the viewport are always rendered with
"sharp edges", like they are exported.
A new button is added, "Show/hide outline of solid model".
When the outline is hidden, it is rendered using the "solid edge"
style. When the outline is shown, it is rendered using the "outline"
style.
In SolveSpace's true WYSIWYG tradition, the 2d view export follows
the rendered view exactly.
Moreover, shell edges are not rendered anymore, since there is not
much need in them anymore and not drawing them lessens the overlap
between various kinds of lines, which already includes entities,
solid edges and outlines.
Before this change, the two buttons "Show/hide shaded model" (S) and
"Show/hide hidden lines" (H) resulted in drawing the following
elements in the following styles:
Button | Non-occluded | Non-occluded | Occluded | Occluded
state | solid edges | entities | solid edges | entities
--------+--------------+--------------+-------------+--------------
!S !H | | | solid-edge | entity style
--------+ | +-------------+--------------
S !H | | | invisible
--------+ solid-edge | entity style +-------------+--------------
!S H | | | |
--------+ | | solid-edge | entity style
S H | | | |
--------+--------------+--------------+-------------+--------------
After this change, they are drawn as follows:
Button | Non-occluded | Non-occluded | Occluded | Occluded
state | solid edges | entities | solid edges | entities
--------+--------------+--------------+-------------+--------------
!S !H | | | solid-edge | entity style
--------+ | +-------------+--------------
S !H | | | invisible
--------+ solid-edge | entity style +-------------+--------------
!S H | | | |
--------+ | | hidden-edge | stippled¹
S H | | | |
--------+--------------+--------------+-------------+--------------
¹ entity style, but the stipple parameters taken from hidden-edge
In SolveSpace's true WYSIWYG tradition, the 2d view export follows
the rendered view exactly.
Also, it is now possible to edit the stipple parameters of built-in
styles, so that by changing the hidden-edge style to non-stippled
it is possible to regain the old behavior.
Before this commit, "emphasized edges" were displayed as well as
exported. An "emphasized edge" is an edge between triangles that
come from different faces. They are helpful in the rendered
display because they hint at the locations of faces, but not
in the 2d export since they just clutter the drawing.
After this commit, "emphasized edges" are displayed but "sharp
edges" are exported. A "sharp edge" is an edge between triangles
where the two matching vertexes have different normals, indicating
a discontiguity in the surface. "Sharp edges" are also displayed
while post-viewing the exported geometry.
According to the C++ standard, "this" is never NULL, so checks
of the form "if(!this)" can be legally optimized out. This
breaks SolveSpace on GCC 6, and probably on other compilers and
configurations.
Fix iconutil build errors: “Iconset contains no image resources.”,
followed by “Failed to generate ICNS.”
The error is produced by iconutil because the AppIcon.iconset contains
only symbolic links to the icon resources which aren’t followed.
Replace the symbolic links with duplicates of the original resources,
as well as conform to the “High Resolution Guidelines for OS X” by
adding additional sizes and dpi.
