Title: KiCAD Raytracing
Post by: Oslaw on August 30, 2018, 09:09:01 pm
Hello,
I just downloaded KiCAD version five. Nice Software but when I tried to use raytracing in the 3D viewer it crashed.
Please can anyone tell me the problem and the solution.

NB: I am using windows 8 pro.

Thank you.

Maybe someone (though most likely not me) would be able to answer if you post a few more details...
Most important:

- your operating system
- KiCad version
- your graphics hardware and driver version
- any error message you get

On the top bar, go to "Preferences" and click on "Accelerated toolset" if it gives any kind of error about OpenGL, that will be your root issue,

I wonder if they will support RTX Realtime ray tracing...  :-DD

You need a solid CPU and GPU combo for this. What is your hardware specs?

The two 4K ray tracing renders I posted here are generated using an overclocked Intel Xeon E3-1231v3 (3.5/3.9GHz 4C/8T Haswell,) 32GB DDR3-1600 memory and Gigabyte GTX 1060 3GB Gaming G1 under macOS High Sierra.

The 3D view, regardless mode, doesn’t work well without a good GPU: it doesn’t work on my HPC workstation, which has dual Intel Xeon E5-2680 (2.7/3.5GHz 2x 8C/16T Sandy Bridge,) 128GB DDR3-1600 memory but an Sapphire R9 380 8GD5 OC graphics card.

It appeared to me that in order to run KiCad 5 smoothly, you need no less than a mid-tier 2016-2017 gaming PC.

Doubt it. Although using RTX to trace a complicated board at 8K resolution would be an achievement, both for nVidia RTX and either AMD Theradripper or Intel Core i9-K.

The reason it doesnt work for certain intel onboard GPUs is due to a bug in the intel openGL driver relating to buffer copies. This is currently be patched.
