Conclusions
Work is in an early stage development but based on a decade of prior workUse of lightweight web-distributed environments a significant development in collaborative modeling and simulationDevelopment is much more rapid (10% compiled binary components, rest script and database) and agent and 3D models can be developed in a fraction of the time.BrahmsVE is funded to product introduction in the Fall of 2005Seeking proof of concept projects (contact [email protected], 831 338 9400)
