QUOTE (djellison @ Jan 27 2010, 10:42 PM)  It's done in the renderer as required by each frame - I've done actual models of most of these as well, up to about 1.2 million polygons, and in the near-field, these renders look better than those models. Certainly several hundred thousand in each rendered frame. Technically - you could pull about 50 million polys out of each one. This is simply awesome. But only 1.2 million polygons - are you thinning the polygon mesh by reducing the number of polygons where the terrain is flat? |

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

Its interesting to compare Doug's Mojave crater flyover to the flyover posted on the HiRise HiClips page: http://hirise.lpl.arizona.edu/media/. (The link to the movie itself is: http://hirise.lpl.arizona.edu/media/clips/...002_web_720.mov)

I prefer your lighting, and you have a better flight path IMO (which is entirely subjective). They have the drop on you with the texture overlay though.

Doug, your animations are great. The flyover on the HiRise site has finer detail on the ground, it seems. Maybe they made their animation with a different data set than the DEMs that they posted. Personally, I also prefer their color overlay.

they are sweet doug - well done!
take a break now, otherwise you'll have nightmares about render farms and tie points. but hey, at least they'll be in 3D! that said, i'm still looking forward to your home-brewed DEM... pete |

Just getting the data that Pete helped me make (in the same way a surgeon 'helps' a patient have surgery) into 3DS Max.
Early results = promising.
