The MovableCoordinateFrame class.
This class extends the coordinate frame with the ability of being programmatically rototranslated.

| MovableCoordinateFrame::MovableCoordinateFrame | ( | float | size | ) |
The constructor.
Initialize the MovableCoordinateFrame data.
| size | the distance from the origin to the endpoint of the arrows. |

| void MovableCoordinateFrame::AlignWith | ( | const Point3f | primary, | |
| const Point3f | secondary, | |||
| const char | axis_1, | |||
| const char | axis_2 | |||
| ) | [virtual] |
Align the coordinate frame to one or two directions.
If the primary direction of alignment is null this function does nothing, otherwise two rotations are performed: the first rotation aligns the axis named axis_1 to the primary direction of alignment, the second rotation never moves axis_1 away from the primary direction.
If the secondary direction of alignment is not null and is not parallel to the primary direction the axis named axis_2 is rotated as much as possible to be aligned to secondary direction.
If the secondary direction of alignment is null the axis named axis_2 is rotated as much as possible to be realigned to its old direction, if this is impossible the remaining axis is used.
| primary | the primary direction of alignment. | |
| secondary | the secondary direction of alignment. | |
| axis_1 | the name of the axis to align to the primary direction, must be a char choosen from 'X', 'Y' and 'Z' | |
| axis_2 | the name of the axis to align to the secondary direction, must be different from axis_1 and must be a char choosen from 'X', 'Y', 'Z' and ' '; if the char is ' ' the axis is choosen automatically. |
