This function showed up surprisingly high on a CPU time profile
when the GUI was unresponsive "doing things". Removed a duplicated
difference in the not-equal case, and switched to abs and a single compare
instead of two compares with a negation. It seems to have moved the
function further down in the profile.
Ubuntu 18.04 uses GTKMM 3.22.2-2, which doesn't support native file chooser.
Commit bc3e09edbf checks if native file chooser
is available, but the result is overridden with a hardcoded define,
probably for debugging.
Removing the debugging code fixes build on Ubuntu 18.04.
Before this commit, if the sketch contain no entities with starting
points off of the axis of revolution, the revolution may fail, which
manifests as the face normals being inverted. The code at the top of
MakeFromRevolutionOf() takes the furthest point from the axis,
projects it on that axis to get a vector. In this case that vector
is essentially zero length except for rounding errors.
After this commit, instead of only considering start points of
beziers, all control points are considered.
Fix by @phkahler.
These are now handled through GitHub status changes, and so the one
notifico instance works just as well, and needs less configuration
in the repository.
We plan to use flatbuffers in the future for the next generation of
the .slvs file format, so flatbuffers are built unconditionally; and
the Q3DO exporter itself is tiny.
Before this commit, the default font chosen for TTF text is Arial
(chosen by the basename of arial.ttf), which isn't present on most
Linux systems, and cannot be redistributed. After this commit, it is
replaced with Bitstream Vera Sans, which can be. Existing files
are not affected.
The font name in the TTF file was artificially modified to add
the (built-in) suffix, which will need to be done if more built-in
fonts are added.
Modifying the original entities instead of deleting them, retains the
original associated constraints. This makes creating rounded rectangles
a lot easier.
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 serves two purposes.
First, we want to (some day) convert these messages into a less
obtrustive form, something like toaster notifications, such that they
don't interrupt workflow as harshly. That would, of course, be
nonblocking.
Second, some platforms, like Emscripten, do not support nested event
loops, and it's not possible to display a modal dialog on them
synchronously.
When making this commit, I've reviewed all Error() and Message()
calls to ensure that only some of the following is true for all
of them:
* The call is followed a break or return statement that exits
an UI entry point (e.g. an MenuX function);
* The call is followed by cleanup (in fact, in this case the new
behavior is better, since even with a synchronous modal dialog
we have to be reentrant);
* The message is an informational message only and nothing
unexpected will happen if the operation proceeds in background.
In general, all Error() calls already satisfied the above conditions,
although in some cases I changed control flow aroudn them to more
clearly show that. The Message() calls that didn't satisfy these
conditions were reworked into an asynchronous form.
There are three explicit RunModal() calls left that need to be
reworked into an async form.
We have a lot of classes with virtual functions but no virtual
destructor, mostly under render/. While this is not a problem
due to how our hierarchy is structured, some versions of clang
warn about this on the delete statement inside shared_ptr.
We could add a virtual destructor, but adding final qualifiers
expresses intent better, is generally more efficient (since it allows
devirtualizing most virtual calls in render/), and solves
the potential problem clang is warning us about.
