| double Point3D::distance_to | ( | const Point3D & | other | ) | [inline] |
Returns the distance between this point and the other point. This is defined by the following function, copied from http://en.wikipedia.org/wiki/Distance#Geometry.
![\[ d=\sqrt{(\Delta x)^2+(\Delta y)^2+(\Delta z)^2}=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2} \]](form_31.png)
| other | The other point to which we are determining the distance. |
