In Part 1 and Part 2 I described an interactive autostereogram viewer. In this post, I thought I start by including a link to a video.

The video shows how multitouch gestures on Microsoft Surface can be used to interact with the models. A depth-map shader then processes the model, and a second-pass converts the depth-map to an autostereogram. As described previously, to avoid distracting the eye when animating a tile-based autostereogram, a randon-dot pattern is used which is regenerated each frame. Unfortunately the video doesn't have the required resolution to see much detail when animating the autostereogram, but the 3D-effect seen when the animation stops is maintained when viewing the application.

Here are some further screenshots:
