Over break, Kevin & Ross helped me out tremendously by getting the stylus to now sculpt a model in the world builder application.
I believe the IPD may need to be slightly adjusted so that you cant see two images. This should be an easy fix, though.
My next steps are now to use the leap motion to grab and rotate the object on screen.
I will add more to this post this week as I work into integrating the leap motion into the world builder application.
