If you want to create embedded interactive 3D graphics for websites with Blender, then check out 3DNP (3D - No Plugins).
While not the fastest or most efficient method on this planet (every frame stored as a separate image on the webserver), it's free and you don't need any fancy 3d plugins to embed the images in your website (which is a major advantage in my humble opinion). In addition, it's really easy to use: I gave it a spin and I had my own name spinning in a web browser in a couple of minutes (no, I'm not going to share it ;-).
The browser support seems to be fine too: 3DNP has been tested for the following browsers:
- Mozilla Firefox
- Microsoft Internet Explorer 6
Here are a few cool examples of the script in action:
Download the 3DNP Package and you'll find clearly written instructions inside on how to create your own interactive web content. If you need help or more information, check out this thread on Elysiun.com.
