nVidia helps NASA reconstruct Mars |
|
|
LONDON JANUARY 19th, 2004 NVIDIA Corporation (Nasdaq: NVDA),
the worldwide leader in visual processing solutions, today announced that NASA is using its technology to reconstruct Martian terrain from transmitted rover data in photorealistic virtual reality, allowing scientists to explore Mars in 3D as if they were actually moving freely on the planets surface. This NVIDIA-powered environment serves as a precise vision and planning system for NASA scientists, allowing them to rehearse a variety of Mars rover scenarios, mapping out moves and experiments, prior to directing the vehicle to undertake actual tasks by flying through highly realistic, 3D reconstructions of the Martian surface.
NVIDIA technology allows NASA to visualise the Martian terrain in photorealistic virtual reality, greatly enhancing scientists understanding of the environment and streamlining analysis, said Laurence Edwards, Mars team lead for 3D visualisation and surface reconstruction from NASA Ames Research Centre. With this capability, scientists step into a visually engaging model of the planets surface and interactively study multiple perspectives front, back, side views of every object the rovers investigate to fully explore all options for rover routes and experiments.
NASA scientists use NVIDIA graphics to visualise high-resolution photographic imagery more than three times as detailed as images sent from Sojourner in 1997. Because the new rovers travel six to ten times farther than Sojourner, taking approximately 6,000 to 10,000 more measurements per foot, the data visualised with NVIDIA graphics is transformed into a particularly detailed, visually enhanced representation of the planets terrain. Each day rover missions are underway, one group of NASA scientists focus on that days rover operation while another plans the following days activities by studying and interacting with this graphically rendered photographic and measurement data taken from targeted, but as yet unexplored Martian terrain.
NVIDIA graphics allow NASA scientists to interactively plan rover movements using 3D photorealistic views of the surface so commands transmitted to rovers result in successful experiments and data gathering, said Edwards. Data transmissions from Mars involve massive amounts of image data that must be quickly viewed, studied and shared. Three-dimensional visualisation in photorealistic virtual reality is the most effective way to maximise distance travelled and knowledge gained.
Two NASA rovers, Spirit, which landed on Mars on January 3, 2004, and Opportunity, which is scheduled to land on January 24, 2004, will explore locations that suggest the one-time presence of water. By converting the data collected from cameras and scientific instruments on the rovers into knowledge through visualisation, NVIDIA graphics technology help NASA scientists learn more about the history of water on Mars in the hopes of determining whether life currently exists on or beneath the surface.
Today, with this new technology, NASA can simulate the lighting and surface conditions expected on Mars when an experiment is to be conducted, said Edwards. If a rock will cast a shadow, obscuring a feature of interest, scientists on the ground will know about this effect in advance and plan around it. In the future, we envision scientists sitting within a large wrap-around display and programming rover movements and experiments using simple touch-screen or voice commands.
