| SbRotationd Structure |
Class for representing a rotation (double precision).
Object that stores a rotation using double precision values. Although Open Inventor fields still store only single precision values, for certain applications it is useful and convenient to be able to store and manipulate double precision values, for example, double precision coordinate data or values that will be used for further computation.
There are several ways to specify a rotation: quaternion (4 doubles, in the order x, y, z, w), 4x4 rotation matrix, or axis and angle. All angles are in radians and all rotations are right-handed.

SyntaxThe SbRotationd type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SbRotationd(Double) |
Constructor for rotation.
|
| SbRotationd(SbMatrixd) |
Constructor for rotation.
|
| SbRotationd(SbMatrixd) |
Constructor for rotation.
|
| SbRotationd(SbVec3d, SbVec3d) |
Constructors for rotation. The rotate From/To constructor defines rotation
that rotates from one vector into another. The rotateFrom
and rotateTo vectors are normalized by the constructor
before calculating the rotation.
|
| SbRotationd(SbVec3d, Double) |
Constructor for rotation. The axis/radians constructor
creates a rotation of angle radians about the given axis.
|
| SbRotationd(SbVec3d, SbVec3d) |
Constructors for rotation. The rotate From/To constructor defines rotation
that rotates from one vector into another. The rotateFrom
and rotateTo vectors are normalized by the constructor
before calculating the rotation.
|
| SbRotationd(SbVec3d, Double) |
Constructor for rotation. The axis/radians constructor
creates a rotation of angle radians about the given axis.
|
| SbRotationd(Double, Double, Double, Double) |
Constructor for rotation.
