A very simple way to embed animation!
If the animation doesn't need to be interactive, I think a gif form will be the simplest.
I modelled in Rhino and animated a turtable view.
I set the number of frames to the 50. So there were 50 images exported.
In Photoshop, 'open' and select 'image sequence'. A sequence of frames can be generated.
The background of frames is automatically white. I want a transparent background, so I deleted the background frame by frame (haven't found a better way)
Embed the gif like a normal image in html.
