Re: “Importance Sampling of Many Lights” - paper: participating media
Okay, I haven't read through the paper, but my understanding from the surrounding context is that you are already given v_0 and v_1 . You use those to compute an orthonormal basis. o_0 and o_1 will be orthogonal unit vectors in the same plane as v_0 and v_1 . o_0 = v_0/||v_0|| and o_1 will be an ort...

Re: bvh build time (CPU vs opencl vs optix vs RTX)
Yeah, I guess it's a matter of tradeoffs between high-quality and high build speed. mpeterson, are you saying that OptiX is building low-quality BVHs?
It would be interesting to see a chart of build times vs incoherent rays/s for several architectures.

Re: bvh build time (CPU vs opencl vs optix vs RTX)
Not that I've seen, but testing Embree vs OptiX build time performance shouldn't be too tricky since they are both open source. Please consider writing something up and posting here.

Re: Linux?
Glad to see a new real-time path tracing engine after all those years :) We are also interested in a Linux version for real-time ray traced scientific visualization on a semicylindrical display wall (which measures 8x3 meters and is powered by eight 4K projectors). Lighthouse seems very interesting...

Re: Linux?
Cool, that's good to hear. What do you mean by render core dlls? Do you mean runtime loaded library (basically deferring algorithm selection)? If so, it is easy to do that in Linux with .so libraries using dlopen.

Linux?
How much of the code is Windows specific? And are there plans to make the project work in Linux?
