Grasping reality through Illusion-interactive graphics serving science

Abstract

I treat three related subjects: virtual-worlds research-the construction of real-time 3-D illusions by computer graphics; some observations about interfaces to virtual worlds; and the coming application of virtual-worlds techniques to the enhancement of scientific computing. We need to design generalized interfaces for visualizing, exploring, and steering scientific computations. Our interfaces must be direct-manipulation, not command-string; interactive, not batch; 3-D, not 2-D; multi-sensory, not just visual. We need generalized research results for 3-D interactive interfaces. More is known than gets reported, because of a reluctance to share "unproven" results. I propose a shells-of-certainty model for such knowledge.
