Four Spheres (AR Modeling Challenge)
- Tim Brzezinski
In this GeoGebra Augmented Reality modeling challenge, the goal is to construct 4 spheres by authoring only 2 surface equations. Modeling Clues: 1) The center of each sphere is located units away from (0,0,0). 2) The x-axis and y-axis are tangent to all 4 spheres.
