> SDF ray marching does a point query against the BVH

Aah, alright. I've written a ray tracer that uses an (L)BVH before, so I'm familiar with how it works for ray tracing. What I couldn't figure out was how you'd use an acceleration structure for ray marching. Now that you spelled it out though, I suddenly think I get exactly how it would work.

Great reply, thanks! It made a lot of sense.

Interesting. Now I'm gettin quite interested in exploring ray marching more.
