Activeworlds Inc. has announced recently that their Active Worlds 3D virtual reality platform now features PhysX SDK integration, including rigid body physics, joints and, more interesting, cloth simulation.
In Active Worlds you can explore virtual worlds and environments that others have built, interact with other users or build structures and areas of your own. Originally this project was started in 1995, so don’t be confused by outdated graphics.
You can find PhysX integration demos in this thread or just spend some time to log into AW and visit physics playground by yourself. Download Active Worlds 5.1 Browser from here, log in as “Tourist” (autoupdate process may occure) and teleport to “AWPhysics” world.
In this world you can find several cloth simulation examples showcasing various features – pressure, two way integration with rigid bodies, tearing, wind acceleration, etc. Don’t forget that you can push objects on scene with your character (default key for running – Ctrl) and interact with some of them using mouse.
Cloth integration itself is pretty robust – it is based on latest PhysX SDK 184.108.40.206, supports multithreading and GPU acceleration (but with global framerate cap of 100 fps we weren’t able to see the difference in performance).
If you’ll find some interesting worlds using new physics features, or just want to share your creation, post links and description in comments.
