Prototypes: Set up #3 - Colour Tracking

The Art of Ping Pong Prototype #3 from Jono Sandilands on Vimeo.

After a bit of getting back to basics in Processing over the past few days - here is another test/rough sketch but this time using colour tracking using a camera above, specifically of a red ping pong ball.

Basically the red ball acts like a pen and draws it's path onto the screen. There are two versions in the video - one which just builds up ellipses and one in which the ellipses become smaller with each update. (Screenshot below)

Be quite good to get this tested on a bigger scale - with actual gameplay. I will use projector from high angle with keystone and create makeshift table with camera directly above.

I can maybe even start thinking about more dynamic graphics and importing vectors. Other thing to think about with this is - people wearing clothing the same colour to the ball - also scope for using a collision sensor or microphone in the table to only record when the ball actually hits the table. - When doing these tests I placed my hand on my test piece of perspex - and could feel the vibration when the ball hits the surface - may not work on larger surface but be worth a test... soon time to get Arduino out.
