Optitrak + Projector touch table/surface

Matlab scripts

In place of the matlab code for reading in optitrak data, the following matlab functions can be used to:

1. read in data sent from the optitrak system
2. set the table top as a plane for reference in matlab, and
3. transform the native coordinate system of the optitrak (x z y ) into another, possibly more familiar coordinate system (x y z).
