Graffiti - whiteboard
Nov 17th, 2008, 9:18pm  
Hi

I have followed a processing course at my school this semester, and i really like it Smiley

I am doing a project the next couple of weeks where i want to build an interactive graffiti installation, and i would love to get some advice and hints from start.

I want to track some movement and project to a screen - like a whiteboard.

Can any of you point me to a library, where i can track a certain color of light (or maybe IR og brightness) and then process it to xy cordinates?

I also need somehow to map the 4 corners of my camera to the 4 corners of the projection - if you know what i mean?

Hope someone can get me started - im finding it a bit hard.

Thanks Smiley

Thank you so much!

I have always thought that the Laser Tag is really nice, but i didnt know you can dowload it and play around with it - nice!

And thanks alot for the Processing Wii sketch - its looking really good.

Ill take a closer look at the different things and also at the Wii library for Processing..
