very nice
The difference is really noticeable. I've spent considerable time with Bryce4 trying to render that region with MDIM data, and the low resolution defeated me--the rounding effect destroyed the sense of scale and reduced Marineris to a drainage ditch in the Oklahoma dust bowl (albeit, Oklahoma with craters). Even in the small new sample I can see a lot of fine detail. Yep, I really look forward to seeing the fly-through.
Thanks.
