Matthew Chadwick has been exploring the creation of GPU-computed chaotic attractors of dynamical systems using the Croquet SDK. The code he is using is based on David Faught's procedural textures code. In this implementation, the cube to the left defines a parameter space for controlling the system. Matthew says that the same code he is developing could also be used for other things like in-world physics simulations. Matthew will make all of this available for public release once the code is ready.

Better avatars for Cobalt are almost ready! Here is a video showing an early test implementation of a motion-cycle enhanced avatar in Cobalt. Peter Moore has been doing a wonderful job with this and in getting the Ogre3D XML importer to work with models developed in Maya or exported from Blender. That means that we will all soon have at least two art paths for getting avatars and other animated meshes into Cobalt worlds. It'll also be great to finally retire the stilted Alice and Rabbit avatars. This particular video also provides a sneak peak at some of the texture and environmental/directional lighting work that I hope to have make its way into the next update of the Cobalt code-base.

This new video by Willi Griephan of Bremen, Germany shows the operation of two Croquet simulation spaces that he created using the Croquet SDK. The first is a falling "Domino" simulation that leverages the Open Dynamics Engine for its physics. The second scene depicts swarm behavior in an aquarium simulation where two members of a swarm can pair, and by doing so, spawn new offspring. The Swarm algorithm that Willi used is described here by Craig W. Reynolds.
