/** \brief CenteredRigid2DTransform of a vector space (e.g. space coordinates) |
| 28 |
|
* |
| 29 |
|
* This transform applies a rigid transformation is 2D space. |
| 30 |
|
* The transform is specified as a rotation around arbitrary center |
| 31 |
|
* and is followed by a translation. |
| 32 |
|
* |
| 33 |
|
* The main difference between this class and its superclass |
| 34 |
|
* Rigid2DTransform is that the center of rotation is exposed |
| 35 |
|
* for optimization. |
| 36 |
|
* |
| 37 |
|
* The serialization of the optimizable parameters is an array of 5 elements |
| 38 |
|
* ordered as follows: |
| 39 |
|
* p[0] = angle |
| 40 |
|
* p[1] = x coordinate of the center |
| 41 |
|
* p[2] = y coordinate of the center |
| 42 |
|
* p[3] = x component of the translation |
| 43 |
|
* p[4] = y component of the translation |
| 44 |
|
* |
| 45 |
|
* There are no fixed parameters. |
