Without OpenMP and with Retina (2x the resolution, means 4x the image size) This means that for this setup, an i7 with 8 logic cpu, it will result on a ~32x slower renderings.
For comparison with a regular setup with a i7 without Retina, if user complained about 60 minutes render, it could result on a 60/32 = 1.8s render (realistic, ~3s .. 6s as I experienced on similar setups) Mario Luzeiro ________________________________________ From: Kicad-developers <[email protected]> on behalf of Jeff Young <[email protected]> Sent: 28 February 2018 11:40 To: Bernhard Stegmaier Cc: KiCad Developers Subject: Re: [Kicad-developers] 3D Viewer "Render current view using Raytracing" is ludicrously slow I can confirm.

Raytracing rendering method is consider to be an "offline rendering" (means, it will take a lot and you can go offline for a coffee and back after a while) However for simple scenes I am not expecting such a long time. Depending on the options I may expect just a few seconds for some scenes. My guesses, for developers to investigate are: - Make sure KiCad on MacOS is build with OpenMP enabled and it is working. This is very important to make rendering to work in parallel. - Since Macs have that "Retina" thing.. could that be the screen resolution is actually 4x (? I dont know how it works..) what it is displaying (comparing to a regular display)?

I admit that I didn’t know what that blue cube in the 3D viewer’s toolbar was for. I guess it’s really a tesseract. Anyway, it re-draws the display and then when you zoom or pan it reverts back to the original rendering (which is quite fast). -a Application: kicad Version: (5.0.0-rc2-dev-26-g0d794b2), release build Libraries: wxWidgets 3.0.4 libcurl/7.54.0 LibreSSL/2.0.20 zlib/1.2.11 nghttp2/1.24.0 Platform: Mac OS X (Darwin 17.4.0 x86_64), 64 bit, Little endian, wxMac Build Info: wxWidgets: 3.0.4 (UTF-8,STL containers,compatible with 2.8) Boost: 1.61.0 Curl: 7.43.0 Compiler: Clang 7.3.0 with C++ ABI 1002 Build settings: USE_WX_GRAPHICS_CONTEXT=ON USE_WX_OVERLAY=ON KICAD_SCRIPTING=ON KICAD_SCRIPTING_MODULES=ON KICAD_SCRIPTING_WXPYTHON=ON KICAD_SCRIPTING_ACTION_MENU=ON BUILD_GITHUB_PLUGIN=ON KICAD_USE_OCE=ON KICAD_SPICE=ON _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected]<mailto:[email protected]> Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected]<mailto:[email protected]> Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected]<mailto:[email protected]> Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
