======================
Primary 3D view planes
======================

This example generates an "unfolded" 3D plot that shows each of the primary 3D
view planes. The elevation, azimuth, and roll angles required for each view are
labeled. You could print out this image and fold it into a box where each plane
forms a side of the box.
