Girado, Bob Kooima, Todd Margolis, Lance Long, Alan Verlo, Maxine Brown, Jurgen Schulze, Qian Liu, Ian Kaufman, Bryan Glogowski Exploring Virtual Mars with the Varrier Source: Dan Sandin, EVL/ Calit2 The Mars demo integrates data from 3 sources. The primary data set is a topographical map collected by Mars Global Surveyor (MGS), a sun-synchronous polar orbiting Mars probe launched by NASA/JPL in 1996. The data was collected between 1996 and 2001, though the probe remains functional as a communications relay in Mars orbit to this day. Topographic measurement was performed by the Mars Orbiter Laser Altimeter (MOLA), giving planetary radius with 1 meter precision at a resolution of 128 pixels per degree, or approximately half a kilometer at the equator.

Topographical data is textured using color imagery composited and color-matched from NASA's Viking Orbiter data collected during the late 70s. The color data has a resolution of approximately 64 pixels per degree. The background starfield is the Hipparcos catalog, a database of 120,000 nearby stars collected by the ESA's HIPPARCOS satellite between 1989 and 1993, rendered as correctly scaled and colored points. The total size of the topographical data set is 46080 by 22528 pixels. At 16-bit precision it consumes 2GB of storage. When rendered using OpenGL, a position, normal, and texture coordinate must be computed per pixel. This expands the data set out to over 30GB, much too large to be rendered efficiently. A topo data caching mechanism was designed to enable real-time display on the Varrier. To begin, the raw topo data set is mipmapped using a linear filter, giving a pyramid of data sets of decreasing resolutions. For each rendered frame, a level-of-detail algorithm recursively subdivides the surface of Mars into square areas, determines which of these areas are visible, and computes the minimum resolution for the optimal display of each. For each visible area, a 45-by-45 vertex geometry page is generated from the raw mipmap level that mostclosely matches the optimal resolution of that area. These 45-by-45 vertex pages are streamed directly to the video RAM of the graphics board, and stored there under a least-recently-used caching policy. The smooth

motion of the viewpoint provides a locality of reference that ensures efficient use of this VRAM geometry cache. This mechanism cycles approximately 40 times per second, with each of the 33 nodes of the 65-panel Varrier maintaining a separate parallel cache representing its own subset of the total view.
