This has been completely broken since 2018 (commit a93283df), and no
one noticed, so it probably wasn't useful. Instead of fixing it, just
drop the feature and a bunch of odd nonportable code.
Turning a reference dimension into a constraint one can make
the sketch unsolvable, which suggests Edit → Undo, which would undo
either too much or nothing at all.
The mimalloc temporary heap is a thread-local object that uses RAII
to manage heap lifetimes even in threads that are created implicitly,
e.g. by OpenMP. However, not all threads are necessarily created by
the application; graphics drivers may create their own threads, and
this can lead to deadlocks when combined with library unloading.
Fixes#657.
The heaps are wrapped in a RAIIish thread_local handler,
since being affined affined to a single thread for allocations is
required by the API
Ref: #642
Resolve issue #489 helix has stairsteps.
Force helix axis line to 8 segments.
Grid triangulation to use a minimum of 4 segments for degree>1.
Adds twist dependence for grid triangulation with degree=1.
Added a max_dt parameter for PWL creation and use that for helical edges.
This is unfortunate, but OpenMP is not available on some toolchains
(most MinGW builds) and, more importantly, breaks the distribution
model we use on Windows, which is a single self-contained executable.
Leave the OpenMP disabled by default everywhere so that we don't have
any second-class platforms where SolveSpace is slower than on first-
class ones.
Fixes#631.
The counter was added solely as a debug feature in commit e7c8c1c8,
which introduced the new Canvas system. It doesn't work all that well
and brings little value, so let's get rid of the visual noise.
This commit continues the work started in commits 521473ee and
e84fd464 that parallelizes certain geometric operations. This commit
cleans up the temporary arena implementations and makes them
thread-safe.
Also, in commit 521473ee, a call to FreeAllTemporary() was added
during initialization to create the heap on Windows. This is now
not necessary as the heap is created transparently on the first call
to AllocTemporary().
When checking the dot product of the tangents `tu` and `tv` to decide
in which direction to split a quad compare it to to LENGTH_EPS instead
of zero to avoid alternating triangle "orientations" when the tangents
are orthogonal (revolve, lathe etc.).
This improves the quality of the resulting triangle mesh.
Commit ea6db67 added an unusual isnan macro:
#define isnan(x) (((x) != (x)) || (x > 1e11) || (x < -1e11))
Commit 8bc322e adds a preprocessor guard that looks like it would
cause the isnan function from math.h to be preferred, but doesn't
actually do that on many platforms, e.g. glibc:
#ifndef isnan
# define isnan(x) (((x) != (x)) || (x > 1e11) || (x < -1e11))
#endif
This commit renames our isnan() to make it clear that it differs
from the standard library operation, and makes it a function.
Fixes#603.
We use std::fabs, but <math.h> doesn't provide it; it worked by accident.
Include <cmath> that provides std::fabs, and switch all other headers to
their C++ variants, too.
VS2013 does not have constexpr support and in general is quite buggy.
There's no reason to use it anymore as even XP toolsets are available
for VS2015 and VS2017.
