Hello!
Did you plan to implement:

• HDRI light
• area lights
• full path tracing
  ?
  It can be useful

[AdamYuan]

Yes, these features are in my TODO list, but may not be implemented in the near future.
Currently I'm working on parallel SBVH construction.

Did you seen https://github.com/jbikker/bvh_article/?
This article series have fast bvh methods

[AdamYuan]

It seems the article only described a naive single-threaded recursive binned SAH BVH constructor. The method didn't make use of multi-core CPU power, and the naive SAH BVH is inferior to SBVH in quality (ray tracing performance).
My parallel SBVH construction system aims to build high-quality SBVH as well as fully utilize CPU power, which is far more complex.

These are some of the references:
