"For too long, many nations, including my own, tolerated, even excused, oppression in the Middle East in the name of stability. Oppression became common, but stability never arrived. We must take a different approach. We must help the reformers of the Middle East as they work for freedom, and strive to build a community of peaceful, democratic nations."
- George W. Bush

BSP Blending
Monday, February 6, 2017 | Permalink

Like my last demo, this is sort of a modern take on an old idea. Sorting rendering back-to-front with a BSP isn't exactly a new idea, but a parallel traversal in a compute shader might be. I've been pondering on this idea for a lot longer than I care to admit, it's probably been in my TODO list for over 5 years, but I finally got around to play with it and see if it was meaningful. My original idea was actually to traverse the BSP on the fly in the vertex shader, which of course is entirely possible, but ultimately decided that it makes more sense to do it in a separate compute pass.

Either way, enjoy the demo, and hope it's useful for something.
