However, the calculation with this option is quite fast. text/html 2024-05-07T08:50:45+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.grogra.de/doku.php?id=groimp-platform:raytracing:raytracer_impl&rev=1715071845&do=diff All the raytracers and their concrete implementations are explained in-depth in these three reports (in German): * * * text/html 2024-06-18T10:21:08+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.grogra.de/doku.php?id=groimp-platform:raytracing:raytracer_options&rev=1718706068&do=diff Twilight Renderer Options The raytracing settings for rendering can be customized under <key>Preferences --> Renderer --> Twilight</key>. The ray processor can be selected from the “Ray processor” drop-down menu. When changing parameter values in the preferences, you always have to leave the field you changed with your cursor before closing the preferences window (just click in a different field) for your changes to take effect. You can find an overview of the different raytracing algorithms t…
