It seems strange that the website of a renderer wouldn’t have any rendered images. What does it look like? Do spectral renderers achieve a better result than traditional rendering methods?
Show me! I want to see the difference!

If you want comparisons then you probably need to look up specific papers to see comparisons for the specific problems they solve.
- incrudible 3y agoBetter is subjective, but the whole point of spectral rendering is to be more objective. The visual difference is minor and its relevance to film/games is put into question by the artistic post processing that inevitably distorts the final result. There are some effects that “just work” with spectral rendering though, so you might save some hackery there.
- alhirzel 3y agoAnother stand-out feature of Mitsuba is its focus on differentiability. Wenzel Jakob is an absolute rockstar in computer graphics, and his group creates informative demo and explanatory videos for their areas of work.
