Lampshade 1 (AR Modeling Challenge)
- Tim Brzezinski
Here's another GeoGebra Augmented Reality Construction Challenge: Using only 2 surface equations (with domain restrictions), reconstruct the lampshade shown in the screencast below. Clues: Cross sections parallel to the xy-plane are squares. Cross sections parallel to xz-plane and cross sections parallel to yz-plane are hyperbolas with and .
