Progress Update

We now have a running touch table with particle-blob collisions!



Please excuse the poor video quality (It's from a cell phone).

If the video isn't working, you can try this link.

In this example we have put note cards on the table. The table finds the outline of the note cards and then uses the outlines (or blobs) in collision detection. This works with hands as well, but it would have been harder to see in the video. If you watch closely near the end of the clip, you can see Matt moving one of the note cards. The blob follows the card, and the particles continue to bounce off the blob as it moves.

Touch Table Interface Update

The touch table is up and running with concurrent threads and the new aparatus from COSI.

Currently we are only able to respond to messages coming at a frame rate of 8.

We will be trying a couple of options to speed up the message listening process:
- listening on several threads instead of just one
- culling out the messages for blobs that have not updated since the last frame

Marching square updates

Marching squares is up and runs interactively.
