This makes image requests that have an image with a hole in it
actually transparent, since otherwise the depth test would prevent
any geometry behind the request from being drawn.
This commit merges all ad-hoc file dialog code, such as the feature
where dialogs remember last location and format, and exposes it
through a common interface.
This commit also significantly improves Gtk dialog handling code.
This commit removes a large amount of code partially duplicated
between the text and the graphics windows, and opens the path to
having more than one model window on screen at any given time,
as well as simplifies platform work.
This commit also adds complete support for High-DPI device pixel
ratio. It adds support for font scale factor (a fractional factor
on top of integral device pixel ratio) on the platform side, but not
on the application side.
This commit also adds error checking to all Windows API calls
(within the abstracted code) and fixes a significant number of
misuses and non-future-proof uses of Windows API.
This commit also makes uses of Windows API idiomatic, e.g. using
the built-in vertical scroll bar, native tooltips, control
subclassing instead of hooks in the global dispatch loop, and so on.
It reinstates tooltip support and removes menu-related hacks.
This commit fixes four issues:
* Instead of WRITE,APPEND, resource.rc was generated using
WRITE,WRITE, which erased #include <windows.h> and prevented
any symbolic definitions (like RT_MANIFEST) from working.
This silently included them using a string type instead,
which did nothing.
* WINVER is bumped to Win7, since that's what we target now.
* Index of RT_MANIFEST is changed to 2, since that's what
it has to be when ISOLATION_AWARE_ENABLED is defined.
* Platform is not restricted to X86 in manifest, since there
is no point in doing so.
All of our executables need resources; e.g. the vector font is
a resource and it is necessary for generation. Before this commit,
the GUI executable loaded the resources in a nice way, and everything
else did it in a very ad-hoc, fragile way.
After this commit, all executables are placed in <build>/bin and
follow the same algorithm:
* On Windows, resources are compiled and linked into every
executable.
* On Linux, resources are copied into <build>/res (which is
tried first) and <prefix>/share/solvespace (which is tried
second).
* On macOS, resources are copied into <build>/res (which is
tried first) and <build>/bin/solvespace.app/Contents/Resources
(which is tried second).
In practice this means that we can add as many executables as we want
without duplicating lots of code. In addition, on macOS, we can
place supplementary executables into the bundle, and they can use
resources from the bundle transparently.
This commit performs two main changes:
* Alters the shaders to use only strictly conformant GLSL 2.0.
* Alters the Windows UI to use ANGLE via GL ES 2.0 and EGL 1.4.
This commit also drops official support for Windows XP, since ANGLE
requires a non-XP toolset to build. It is still possible to build
SolveSpace for Windows XP using:
cmake -T v120_xp -DOPENGL=1
There are two main reasons to desire an OpenGL 2 renderer:
1. Compatibility. The compatibility profile, ironically, does not
offer a lot of compatibility, and our OpenGL 1 renderer will not
run on Android, iOS, or WebGL.
2. Performance. The immediate mode does not scale, and in fact
becomes very slow with only a moderate amount of lines on screen,
and only a somewhat large amount of triangles.
This commit implements a basic OpenGL 2 renderer that uses only
features from the (OpenGL 3.2) core profile. It is not yet faster
than the OpenGL 1 renderer, primarily because it uses a lot of small
draw calls.
This commit uses OpenGL 2 on Linux and Mac OS X directly (i.e. links
to the GL symbols from version 2+); on Windows this is impossible
with the default drivers, so for now OpenGL 1 is still used there.
The states are:
* Draw all lines (on top of shaded mesh).
* Draw occluded (by shaded mesh) lines as stippled.
* Do not draw occluded (by shaded mesh) lines.
As usual, the export output follows the screen output.
Also, use a more appealing isometric projection if none specified,
instead of orthographic.
Also, use the scale, offset and projection from the viewport at
the time of export.
This commit integrates the vector font in the resource system, so
that cross-compilation would be easier and a custom font could be
used without recompilation.
The font handling code was carefully written to lazily load glyphs;
as possible; in practice this means that startup is less than 15ms
slower after this commit, most of it spent in inflate().
This also reduces executable size and makes compilation of
glhelper.cpp much faster.
This commit integrates the bitmap font in the resource system, so
that cross-compilation would be easier.
The font handling code was carefully written to do glyph parsing
lazily; in practice this means that after this commit, startup
is less than 25ms slower, most of it spent in inflate().
This should also result in faster rendering, since there is no
rampant plane switching anymore; instead, all characters that are
actually used are stashed into same one texture.
This commit integrates icons in the resource system so that they
can be loaded (or reloaded, without restarting) in @2x mode, which
will be added in a future commit. png2c is no longer necessary.
png2c used to perform the following transformation:
if(r + g + b < 11) r = g = b = 11;
This is now achieved by switching the icons to RGBA mode and adding
alpha channel with the following imagemagick invocation, which is
equivalent to the transformation above:
for i in *.png; do
convert -fuzz 4% -channel rgba -matte \
-fill "rgba(255,255,255,0)" -opaque black \
$i $i
done
The Debian package solvespace now includes /usr/share/solvespace;
this should be split out into solvespace-data later.
