I've modified my Mars Explorer terrain engine to use the new HiRISE data. This video shows me flying around the Gullies DEM. It's running at about 30 fps.

I've upgdraded my RAM and tweaked the software and now I'm able to use the full HiRISE texture resolution (~25cm). Here's my first animation at the full resolution, this one shows Candor Chasma.

Simply amazing ! your best one yet ...
I've upgdraded my RAM and tweaked the software obviously you must be using a true 64 bit operating system with > 4GB RAM EDIT: I just read your video info in youtube: QUOTE The animation was created using Mars Explorer and was captured in realtime. in realtime !! Wow, that is very impressive: rendering such high quality, wide horizon views with what must be several millions of polygons at 30 fps ... I thought this nearly impossible without exploiting hardware/GPU to the limit. For example, the relatively simple render engine I wrote for my still DEMs (written directly in plain C, optimized code but without GPU support) takes several seconds to render 10 million polygons. |

Simply amazing ! your best one yet ... obviously you must be using a true 64 bit operating system with > 4GB RAM I upgraded from 2GB to 4GB on 32bit Vista (only 3GB is probably availiable because its 32bit). I have to crop the datasets to 8192x10240 for the DTM and 32768x40960 for the texture. In the case of Candor I only had to remove about 5% of the dataset because it is only just over that size, but for the Mojave dataset I can only use about half of it. I need about 6GB and a 64bit OS to not have to crop any of the datasets. |
