Late last week I stumbled upon a few HiRISE derived DEM's (Randy Kirk works his magic once again!)

http://webgis.wr.usgs.gov/ftphirise/index.jsp (URL now down)

I'm working on both Vic Crater and the Columbia Hills. Fortunately, now I've got a Mac, I can use ISIS. I've figured out a fairly simple flow ( isis2raw as 16 bit unsigned, and then imported into Photoshop ) to take DEM CUB's and make 16 bit PNG's smile.gif

Just to demo how important that is for me as an animator - sliced comparisons of 8bit vs 16 bit.

A busy week unfortunately, but animations of various sorts are in the pipeline.

I think it's being selective in not generating more polys than the are pixels to enjoy them - so in the distance, they are less dense. It regenerates every frame, producing the polys as they're needed. You can turn it up and down, and I basically turn it up till till it start having artifacts, or stops improving in detail. There are far better ways of dong it - you and Adrian have the know-how there. I'm just a tempramental artist smile.gif
