Interactive 3D on the Web (i.e. Web3D) is becoming a reality with COLLADA as the enabling intermediate format. The first PaperVision3D game Xwing Obstacle Course lets you control a simple fighter in real-time 3D over the web using Flash. The posting describes the workflow using COLLADA models. The COLLADA for the Web presentation from GDC explains how COLLADA, Ajax and X3D are used within Flux to enable real-time streaming 3D virtual worlds and games over the web.
