Since I experimented webgl stuff, some clients start to think seriously to make 3d apps on the web. For one of them I have done a Vehicle Editor. The idea is to select a chassis and customize it with different element you can plug on it.
The pipeline use blender file exported to OpenScenGraph format and then it convert it to osg.js . If you have a modern browser with WebGL, have a try with real time version or try the video here or on youtube
