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 hope to make a download of the software available in the next week or two.

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.

obviously you must be using a true 64 bit operating system with > 4GB RAM smile.gif

EDIT: I just read your video info in youtube:

The animation was created using Mars Explorer and was captured in realtime.


in realtime blink.gif !! 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.

I have a 8800GTS which can give me up to 250 Million polys/second. I render less than 3 Million polygons per frame as I am using an LOD alogirthm. I get mostly above 60 frames per second. Now I am using the full texture resolution there is some slowdown if I turn quickly because of the amount of texture data that is being loaded from system memory to the graphics card. More RAM on the graphics card should cure this though.
