A 3D web plugin called Pulse 3D was launched in 1999 and seems to have defunct around 2006. It could render interactive 3D characters in-browser. A whole article on how it worked can be found here. A video of a Road Runner and Wile E Coyote animation made in Pulse 3D in on YouTube.
The website is www.pulse3d.com, and it looks like the installer for the player is still there on the Wayback Machine, so there's a chance these could be recovered. All their projects can be found here.
