Congrats. It looks great. Lots of things in there to try out in our renderer... [SMILEY :)]

I want to award one bonus point each for mentioning both the Commodore Amiga as well as AltiVec. Motorollin'! [SMILEY :)]

I don't understand. If Timo Aila's work is the state of the art of gpu ray tracing, then why don't dicuss that in the thesis, instead talk about path regeneration and stream path tracing??

Because your Ph.D. thesis is about what you have done, not about what someone else did. [SMILEY :-)]

Oh? I thought path regeneration and stream path tracing are also someone else's works.

It is briefly discussed in 6.1.1. Thing is, Aila & Laine provide ray traversal kernels which are state-of-the-art, and this is used as a building block in many other algorithms, including path regeneration and streaming path tracing. It's basically a low-level block that I take for granted, and build upon.

It never was the state of the art(or for a short time until Fermi came out). Even they themselves didn't use the 'persistent thread' thing anymore in their later paper, it didn't make sense on Fermi. I never quite understood their paper, and I never bothered to try out their persistent threads. My simple path tracer that actually did some real shading had a similar speed as their persistent threads approach at the time so I never bothered.
