I'm trying to write an app which allows the user to move a pencil-shaped object (the trackable object) toward and into a fixed position target - in this case it's a flat plane consisting of a bulls-eye target. (Analogous to threading a needle, or throwing a dart)
I've found information in other threads about creating a 2D plane, but they all involve augmenting the plane against the modelViewMatrix, which means that the plane moves along with the trackable.
What i'd like to do is to fix the position of the target in space, and have the user try to move the trackable toward (and be occluded by) the target plane once they successfully intersect, but can't seem to work it out.
Hoping someone will be able to help :)
