Wiimote Interactive Whiteboard / Code explanation
« on: January 13, 2008, 07:02:00 PM »
Hi, i just read a post about the math behind the whiteboard, and I too can't figure it out. I read the whole project code and I understand almost everything, except some particular C# stuff which I believe I can find in some tutorials. My problem is with the Warper.cs file.

I see the identity matrix is set and that the source matrix is formed with 4 points (x0,y0 through x3,y3) and I understand the matrix multiplication function , the thing is, I can't seem to figure out what does the computeSquareToQuad, computeQuadToSquare and warp functions do.

I believe they are supposed to translate the IR led's position to screen coordinates, am I right? can someone explain the math behind it or point me into the right direction to read some literature please?

I would like to study the possibility of using 2 Wiimotes, one on top and one sideways on the board so as to increase resolution but first I gotta see the math behind it.

Thanks a lot!

Hello guys, my name is Akram Shehadi, and although my name might not suggest it, im Mexican. I just finished my college courses, major in Computer Science and am about to do my thesis when I got totally hooked up with Lee's awesome ideas.

So here I am, completely new to C# but somewhat proficient in Java and C, so I'm guessin it should not be *too* hard to pick up, hoping to build upon the Whiteboard project, particulary because of the cost/benefit ratio so significant and potentially viable to a country like mine.
