Commissioned by Geoff Briggs, Summer 2002Used the MOLA 1/128 dataset as terrain sourceMOLA data translated into .DEM by 3DEM, seamlessly stitches a terrain patch. Outputs elevation profiles of any path, allows verification of elevation, latitude and longitude or areaStep to mimic the actual colors and textures of the Martian surface using orbital photos of surface and atmospheric images. Artistic license employed: thinning the clouds, adding stars, etc. Artistic license of surface simulation.

Goals:Build on the positive experience from Pathfinder/1997
and offer a high fidelity yet low bandwidth 3D interactive experience of the MER/2004 surface operations and support a wide range of public outreach goals.
3D virtual terrain to be included modeled from real MER data, simulation of vehicles making traverses, driving the virtual rovers through alternate traverses.
Create a direction for proposed mission visualization (Mars Drill)

Conclusions
Work is in an early stage development but based on a decade of prior workUse of lightweight web-distributed environments a significant development in collaborative modeling and simulationDevelopment is much more rapid (10% compiled binary components, rest script and database) and agent and 3D models can be developed in a fraction of the time.BrahmsVE is funded to product introduction in the Fall of 2005Seeking proof of concept projects (contact [email protected], 831 338 9400)
