Re: [Tip] FreeCAD does square helices!

Hi! As always using python and some math you can create everything;) Using the Macro 3D Parametric Curve and equations (tune the "30", "10" and "0.05" numbers): (30+10*cos(t))*cos(0.05*t) (30+10*cos(t))*sin(0.05*t) 10*sin(t) you can plot a helix wrapped around a torus. http://en.zimagez.com/miniatur...

Re: What is the system requriments for Freecad?

Well, the biggest problem on the real hardware is lack of "desktop" OpenGL 2.0 implementation. VideoCore IV documentation has been released a while ago, maybe is it possible to write such implementation? Who knows... Freedreno team did it for Adreno.

Re: What is the system requriments for Freecad?

Surprise, FreeCAD is available in the standard Raspbian repositories. Unfortunately, I have no real hardware to test FreeCAD. http://en.zimagez.com/miniature/fcpi.png The image shows FreeCAD running on the Qemu-ARM emulator.

Re: compile for Windows from Linux and run in wine

And it's pretty straightforward on Debian/Ubuntu, Disagree, it was pretty straightforward two years ago, when FC was a much simpler package. Today you have to meet dozens dependencies and resolve problems - coin60 vs coin80, pivy (internal or external?), shiboken (what it is? something about that j...

Re: Anti-Aliasing

It may be a Debian wheezy issue. I got the same message with a Radeon HD4670. OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV730 OpenGL version string: 2.1 Mesa 8.0.5 OpenGL shading language version string: 1.20 IIRC MSAA for R600g (Radeon HD2000-6000) driver was introduce...

Re: Anti-Aliasing

Maybe someone else can confirm this but none of the MSAA types seem to work on my Ivy Bridge HD4000 chipset. Works fine for me. glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile x86/MMX/SSE2 OpenGL core profile...

Re: Anti-Aliasing

From the error message I think, that graphics card was gone out of RAM. FYI: If you are using open source drivers, you can draw some graphs (to monitor VRAM usage) inside the FreeCAD GL viewport: GALLIUM_HUD=VRAM-usage,requested-VRAM freecad MSAAx8, 300MiB memory usage: http://en.zimagez.com/miniat...

Re: HTML 5 and WebGL support (discussion)

I read a interesting article about amazon which rewritten all the PHP stuff they had in C++, cause it was twice the fast and they could spare half their server. So for serious stuff you will not use PHP or Ruby on Rails in the future.... Never say never. Facebook HipHop PHP VM https://github.com/fa...
