3D cursor with FlockOfBirds

[giancamati]

Good Morning,

I am developing a 3D virtual environment in which I tracker my hands with flock of birds devices. Now, with the Vanda I would like to implement a 3D cursor. I visualize my 3D cursor as a sphere and I would like to understand if there is a way to fast determine in my sphere intersects an object in the scene. If there is an intersection I pick the object up and move, otherwise nothing happens.

Thank you so much.
