Over the weekend I finally got around to coding up one of the samples I've been meaning to do: a full HDR pipeline in XNA that uses LogLuv encoding. It's pretty neat: it lets you switch between fp16/LogLuv, and also lets you switch on and off multisampling and linear filtering fordownscaling so you can see the results of linear filtering when LogLuv is used. Plus I don't think there's any samples out there that show you the basics of HDR with XNA, so I think it's something people would find useful.

I haven't finished with my write-up yet, but I did take a sweet screenshot:





Look at the bloom on that teapot! And yes I know...teapots and Uffizi Cross have been done in just about every other Direct3D sample. What can I say, I'm not that creative.
