17. Commissioned by Geoff Briggs, Summer 2002 Used the MOLA 1/128 dataset as terrain source MOLA 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 area Step 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. IV. Mars Planetary Fractal Model

22. MER and FMARS Analogue Habitat on the surface Mars Planetary Fractal Model

23. 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) V. Drive On Mars

24. Drive On Mars Adobe Atmosphere player (~1.4MB web plugin) wide distribution, multiple platforms Viewpoint format for animated objects Havok physics in Atmosphere for realistic terrain following Shadow casting, dynamic lighting (Mars “sols”) JavaScript web-based scripting High degree of compression, worlds/rover in demo <1MB uncompressed, less compressed Web-based, fully distributed, multi user chat server option Future: integrating pancam 3D mesh data (VizOpps project)

30. Conclusions Work is in an early stage development but based on a decade of prior work Use of lightweight web-distributed environments a significant development in collaborative modeling and simulation Development 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 2005 Seeking proof of concept projects (contact damer@digitalspace.com, 831 338 9400) damer@digitalspace.com
