| SbRotation Structure |
Class for representing a rotation.
Object that stores a rotation. There are several ways
to specify a rotation: quaternion (4 floats, 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 SbRotation type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SbRotation(Single) |
Constructor for rotation.
|
| SbRotation(SbMatrix) |
Constructor for rotation.
|
| SbRotation(SbMatrix) |
Constructor for rotation.
|
| SbRotation(SbVec3f, SbVec3f) |
Constructors for rotation. The rotateFrom/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.
|
| SbRotation(SbVec3f, Single) |
Constructor for rotation.
|
| SbRotation(SbVec3f, SbVec3f) |
Constructors for rotation. The rotateFrom/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.
|
| SbRotation(SbVec3f, Single) |
Constructor for rotation.
|
| SbRotation(Single, Single, Single, Single) |
Constructor for rotation.
