14.12.8 The length squared of a segment in space: distance2
See Section 13.14.3 for squares of lengths in two-dimensional
geometry.
The distance2 command finds the square of the distance
between two points.
-
distance2 takes two arguments:
P,Q, two points or two lists with the coordinates of the points.
- distance2(P,Q) returns the square of the distance
between P and Q.
Example.
Input:
distance2(point(-1,1,1),point(1,1,1))
or:
distance2([-1,1,1],[1,1,1])
Output:
