20 Calculating Distances Between Points
QuickDraw3D provides routines that you can use to determine the distance between two points. QuickDraw3D also provides routines that you can use to determine the square of the distance between two points. These distance-squared routines are much faster than the simple distance routines and are therefore recommended for situations in which only relative distances are important to you.
