This commit finishes the removal of OpenMP from the KiCad codebase.
Removed in this commit are the OpenMP calls in 3d-viewer and
qa/polygon_triangulation as well as all references in CMakeLists.txt
std::thread is used instead for multithreaded computation
There is no need to use mm_malloc at this moment. Explanation:
1) It was planned that there was advantadge to use aligned memory but it
was not measured the performance. 2) aligned memory is needed for use
with SIMD (i.e: SSE) but that is not used at moment.
Fixes: lp:1626278
https://bugs.launchpad.net/kicad/+bug/1626278
+re-implement anti-aliasing, making it more acurate, not blured, better
and much faster (unsing much less lines of code)
+rewrite some function on camera and raypacket.
+small improvements on raytracing realtime, remove useless ifs
comparisons.
* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
