mitsuba 3 is offline ray tracing renderer?

[bipul-mohanto]

I am searching for a real-time path-tracing rendering engine for research purposes, where at least the naive path tracer is built-in.

I know mitsuba 2 and 3 are very popular in the physically-based rendering community. I checked some documentation of mitsuba 3. My initial guesses are:

• mitsuba has only ray tracing algorithm in it, not path tracing. Am I right?
• The ray tracing is offline, not real-time. Am I right?

Please correct me if I am wrong.

Hi @bipul-mohanto

Mitsuba has a standard path tracer implementation available (documentation). If you're looking for an algorithm where the rays start at a light source, this is also possible with Mitsuba using the ptracer.

Mitsuba is not a real-time renderer. There is an important focus on performance, but real-time performance is not an immediate goal of the project.

Thanks @njroussel for your clarification.
