3D angle on a stick figure view
The absolute angle between two vectors is entirely independent of any projection, let alone
the three projections offered for 2D angles. Yet for any given 3D angle there exists a view in
which it might be visualized: the Variable-axis Stick Figure provides a tool with which to look
around the figure from all points of view, proceeding by trial and error to find the optimal
vantage point from which the angle will appear as described by on the graph. (The stick
figure must be appropriately joined up, using virtual marker connections to represent plane-
normal vectors where necessary). There is no automatic re-orientation of the Variable-axis
Stick Figure to facilitate viewing a 3D vector angle.
