* An ellipsoid in OOPSE is restricted to having two equal |
| 51 |
> |
* equatorial semi-axes. OOPSE treats the "special" axis as the |
| 52 |
> |
* z-coordinate in the body fixed reference frame. That is: |
| 53 |
> |
* |
| 54 |
> |
* z^2 / a^2 + (x^2 + y^2) / b^2 = 1 |
| 55 |
> |
* |
| 56 |
> |
* If a >= b, the ellipsoid is a prolate spheroid, and if a < b, |
| 57 |
> |
* the ellipsoid is oblate. Ellipsoids are specified in the constructor |
| 58 |
> |
* using an axial length (a), and a equatorial length (b). A Vector3d |
| 59 |
> |
* can be used to position the center of the ellipsoid, and a rotation |
| 60 |
> |
* matrix can also be used to orient the ellipsoid to a preferred lab-fixed |
| 61 |
> |
* coordinate frame. |
