Automated Generation of Three-Dimensional Virtual Worlds for Task Explanation

Abstract

During this quarter, Norman Chin presented a paper on our work on analytic shadow-generation for convex area light sources at the 1992 Symposium on Interactive 3D Graphics. An image created using our implementation was also submitted to and accepted for the SIGGRAPH '92 Technical Slide Set. A variant on this work is incorporated in the visibility checking algorithm we use in our IBIS intent-based illustration system, which is part of our knowledge-based augmented reality testbed. The visibility checking algorithm is described in a paper that was accepted for publication in The Visual Computer.
