* \brief Compute the signed distance from a N-dimensional sphere. |

| 29 |
|
* A instance of sphere is defined by a set parameters. The first parameter |
| 30 |
|
* is the radius and the next SpaceDimension parameters represent the center. |
| 31 |
|
* The first parameter forms the set of ShapeParameters and the remaining |
| 32 |
|
* parameters the set of PoseParameters. |
| 33 |
|
* |
| 34 |
|
* This class is templated over the coordinate representation type |
| 35 |
|
* (e.g. float or double) and the space dimension. |
