3D Distance
Description
This applet illustrates the distance between 2 points in three-dimensions. The two points A and B can be moved in the 3D view.
The left view shows the coordinates of the points as an (x,y,z) array. The distance in each coordinate direction is then shown as . Then the length is calculated.
An additional value of the unit vector which indicates the direction of the vector by dividing the coordinate distances by the total length.
Two check boxes allow you to display the coordinate path from A to B and the unit vector in the three dimensional view.
