Hi Jakub,

I didn't change anything that makes the Raytracing faster :O Did you upgrade your CPU?! :)

The only additions was the progress bar (that actually should slow it down a bit..) and I added a feature that buffer the image after it finish the render, so if it have to render the screen again (and nothing had changed), it will just display the last render.
It fixes this issue:

That was probably what you experience before, you are getting double or triple renderings :/
But should not be a problem now.


> I have one question. Do you planning to have some settings for raytracing ?

Menu->Preferences->Render Options->Raytracing Options:
- Floor
- Refractions
- Reflections
- Anti-aliasing
- Post-processing

its there for some time.

Mind that you need Refractions in order to see the copper tracks if soldermask is enabled (you need that the rays of light refract through the soldermask!)
(maybe in future I could get some texture approach)

You can also disable some layers or the zone filling to get more speed..

I am still looking on this one.. but it is very hard to catch... so it makes debug complicated if I cannot reproduce it :/

Subject: Re: [Kicad-developers] Some new sweet features on the new 3D-Viewer

Hi Mário,

I was testing 5933.

The raytracing is much more improved. Even on fullscreen is much more
faster. When I zooming or rotating in raytrace mode then it is a lot
better. And the rendering progress works well. Great work.

I have one question. Do you planning to have some settings for
raytracing ? For me a reflections are very heavy and somehow unreal, so
it can be nice to have some settings (antialiasing, reflectance, ..)

The "squarish segments" are less frequent, I saw them only one.

Thank you.

Jakub
