Standard ray tracer The Standard Raytracer option produces rather unnatural-looking images, as this algorithm ignores indirect lighting for diffuse materials and always calculates ideal reflections for reflective materials. However, the calculation with this option is quite fast. text/html 2025-02-07T10:01:29+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:08_light:01_cpu:02_renderer:02_implementation&rev=1738922489&do=diff Implementation All the raytracers and their concrete implementations are explained in-depth in these three reports (in German) * * * text/html 2025-02-07T10:06:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=01_user_documentation:08_light:01_cpu:02_renderer:03_option&rev=1738922809&do=diff 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.
