## Intersection of Sphere and Line

Given a sphere and a line, the intersection points are calculated.

The Sphere may be entered by its center and radius, the line in parametric representation
or by two points.

### Example:

Sphere :
========
K : M(5|5|5) , r = 5
Line :
======
-> | 1 | | 1 |
g : x = | 0 | + r·| 1 |
| 0 | | 1 |
Intersection points :
S1(2,818665|1,818665|1,818665)
S2(8,514668|7,514668|7,514668)
Length of the chord :
s = 9,8657657
