Thanks for your great work.
I tested your single ray tracing API, it is super faster than other ray tracing framework. I have two question about the Embree:
1. The advanced features on Embree are very clear, but if I need to know the details, for example, why the single ray interaction on Embree is so fast, is there any materials or document available to describe the algorithm with more details?
2. The Embree provide the single/multiple ray interaction API, but if I need to implement the interaction between beam and scene (the basic element is replaced from the ray to the beam), how should I do? (The beam is defined by three edge rays that intersect in the focus of the beam, as the attached figure below shows.)
I am appreciated for your help. Thanks again.
