Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Spectral Ray Tracing
Some examples of Spectral ray tracers
Mitsuba is an open source research renderer with lots of cool features like differentiable rendering. https://www.mitsuba-renderer.org/
Maxwell has two spectral modes of varying accuracy. The more complex method is often used for optics. https://maxwellrender.com/
Manuka by Wētā FX is spectral and has been used in several feature films https://dl.acm.org/doi/10.1145/3182161 and https://www.wetafx.co.nz/research-and-tech/technology/manuka

How do you know if a renderer renders the model colors correctly?
https://www.mitsuba-renderer.org/ is considered a high quality, freely available reference implementation for many of these issues.

Mitsuba 3 Physically Based Renderer
IMHO it's "differentiable" that's the most interesting part of this. There's tons of physically based renderers.
It's odd that that word doesn't appear on http://www.mitsuba-renderer.org/ - unless "retargetable" carries a similar meaning?

Spectral Ray Tracing
If you want to look under the hood and find the big production ones like too complex, I can recommend peeking at this one. It's a great example example of just the minimum of a spectral path tracer https://github.com/TomCrypto/Lambda
- How much boilerplate code you need to write a ray-tracer?
What are some alternatives?
