Whilst the above image is sort-of pretty, its not the intended result!
Running against the reference rasterizer generates the expected greyscale image without any funky contour lines [rolleyes]
Nvidia, I'm looking at YOU.
Luckily I'm only on 100.59 and I've heard the 100.64's are out now, so I guess I have to try those tomorrow...
Anyway, progress on the book for the last couple of days has been far too slow [headshake]. I'm most of the way through finishing Chapter 3 - should get that done fairly quickly tomorrow. Then the rest of the weekend is sorting out Chapter 2 (Light sources).
It'll be a good weekend if I can have chapters 1, 2, 3 and 4 completed. The first three are the biggest, which means its slightly more feasible that I'll get 5, 6, 7, 8, 9, 10 done in the remaining 10 days [lol]
