|
| An initial prototype of Scenario 2 with one rover was built to prove the mapping between objects and areas (anchors in Atmosphere language) and show that a rover could be driven across the virtual canal. Additional models such as the articulated avatars, geologic sample box and other objects were created in this phase. Figures 9-13 below show an actual space suit used at HMP/FMARS and virtual models of articulated space suit figures in the virtual world for FMARS. |

Putting it all together
|
| Combining the modeling of the FMARS interiors and exteriors, and all objects including avatars, together with a simplified virtual model of the immediate environments of the FMARS habitat, we produced a simulation environment ready to run the Brahms scenario 2 model. Figures 14-17 below show the virtual habitat and areas defined for the simulation, as well as an early example of a rover traverse of the virtual Lowell Canal. |

| Figures 18-20 below show the combined simulation running the JavaScript described in Appendices 4 and 5 to produce the final visualization of scenario 2: two astronauts, each boarding rovers, one with a geology kit, traversing the canal where one astronaut dismounts and retrieves a sample, whereupon both astronauts return in their rovers to the habitat. |
