Here is a draft of our paper Real-time Interactive Gravitational Lensing summarizing the project. Since we expect serious latency problems, including total dropout of communication, the two instances, voodoo.cave and voodoo.duo, operate independently. We use Birgit Bluemer and John Estabrook's generalization of the classic Einstein approximation to his relativistic field equations. The lens drifts about an invisible cube, bouncing off the walls. The avatar mimics its player's head and hand, and was designed by artist Kris Moskwa.
Hand gestures control the motion of the player in the scene.
The actual performance of this piece is excrutiatingly sensitive to the performance of the multiprocessor onyxes and especially to the network. We have made every effort to finagle the action so that every malfunction can be blamed on others. More pix and info , and some trophy photos from Supercomputing'98. Here is an interim summary of our project November 1998.
