Resolution-Mapped Shadow Maps

I've been looking at Aaron Lefohn's PhD dissertation:

Glift: Generic Data Structures for Graphics Hardware

and I thought it would be worth drawing attention to the resolution-mapped shadow map technique he has developed (along with others, quite a long list). PDF pages 103-138.

This next PDF gives a nice overview (pages 52-71):

The technique comes out of the development of Glift which is all about easing the usage of complex data structures on GPUs (originally for GPGPU apps).

The way I look at it, this is just another forward-looking technique. I think it's interesting because it's high-quality and tweakable for performance/memory-consumption/quality. It seems to scale quite well, too.

Also, I imagine, it'll prolly get a tasty boost from running on a D3D10 GPU.
