Abstract : Our research emphasizes modeling algorithms and data structures to support physical simulation and prototyping in a distributed and collaborative virtual environment. One new proposed thrust in geometric modeling algorithms is the use of algebraic splines (A-splines) in two, three and higher dimensions. The other main focus is to develop and demonstrate specific paradigms in our reconfigurable and interoperable distributed virtual environment SHASTRA, which would allow collaborating users to efficiently build three dimensional models from large measured point data sets (jet engines, automobiles, tanks, artificial implants, ...), generate surface and volume meshes coupled to these models and interactively modify the domain in response to the solution of physical phenomena (stress analysis, fluid dynamics). Furthermore, because of the SHASTRA software's distributed client-server nature, other modeling and simulation packages could be easily connected and interfaced for added functionality.
