VastPark is a platform for creating and hosting virtual worlds using the Immersive Media Markup Language (IMML). IMML allows defining 3D scenes, textures, audio, video and other elements using an XML format. Scenes can be deployed for single or multi-user access. The platform supports extensibility through plugins and uses open standards like WebGL for rendering on different devices.

Editor's Notes

#9: 3D models, Primitive (Box, Cylinder, Cone, Sphere, Plane), Camera, Shader, Video, Effect (particles), Script, Trigger, Background, Plugins, Widgets, Anchors, Timelines, Lights
#20: Crane demo
#22: Piano demo, HQ demo (behaviour based capture) show codec acquisition
#23: Two main goals: Better looking, more realistic avatars. Reusable way of generating them
#25: Demonstration of default animation + override animation
#29: Provides an avenue into the virtual world ecosystem with zero-barrier to entry
