Re: FreeCAD renderer is CPU bounded (at least for me)

In the file https://github.com/FreeCAD/FreeCAD_sf_master/blob/master/src/Mod/Part/Gui/SoBrepFaceSet.h you could activate the define #define RENDER_GLARRAYS (by replacing #if 0 with #if 1) and check if this makes higher use of the GPU. No bigger difference for "Panels". Unfortunately both GPU usage ...

Re: Series of articles about the pitfalls of parametric edit

Hi arcol! It's hard to replicate the video without "Body" container. Unfortunately the "Body" is not implemented in the master FreeCAD so far, only in the "assembly" branch. In your file cylinders and rest of model aren't connected with each other. You do boolean fusion and them add a pad on cylinde...

FreeCAD renderer is CPU bounded (at least for me)

I don't want hi-jack that thread , but only share a small observation. http://en.zimagez.com/miniature/fcusage.png I opened Yorik's the "panel" file , disabled Shape2DView projections and made the view turntable. Then observed CPU (via top) and GPU ( via radeontop - a Linux tool, works with Radeons ...

Re: Mirror bottom in Z-

That's display gravy. Evidently it's cool to look at, but it must be CPU/GPU intensive, would it? Would it be possible to not compute when the user translates or rotates the view? Then it would not impact display performance too much. Is it useless? Quite! :D But pro CAD software already do it: NX ...

Re: Mirror bottom in Z-

If your talking about having that feature in the standard 3D view, that would take a brand new 3D render engine. My first thought on that would be something like the quake render or some other 3D game engine, but all of those work from meshes and that would not be that compatible with FreeCAD I wou...

Re: 2014 Google Summer of Code

I learnt how to do some very simple stuff with BRL-CAD a few years ago, when FreeCAD was, I think, about 0.8 or 0.9. At that time, with FreeCAD being very useless ... :oops: ... I spent some time with BRL. It was very difficult to learn to use, nothing like as easy as FreeCAD. They had a new GUI ca...
