My aim for this assignment was to make one pattern reveal a basketball and to make another reveal a hoop, and then eventually have the basketball be able to go into the hoop….I got so far as to get the basketball and hoop to appear when their respective patterns are on screen. I want to:
a) know why this thing is so damn shaky,
b) figure out where/if there are any clear, English javadocs for nyartoolkit?
c) make 3D models of these two things, not just 2D images
d) figure out how to interact between these two amidst all the different matrices etc.
