The default constructor just initializes a valid rotation. The actual value is unspecified, and you should not depend on it.

Construct a new SbDPRotation object initialized with the given axis-of-rotation and rotation angle.

Construct a new SbDPRotation object initialized with the given quaternion components.

The array must be ordered as follows:

q[0] = x, q[1] = y, q[2] = z and q[3] = w, where the quaternion is specified by q = w + xi + yj + zk.

Construct a new SbDPRotation object initialized with the given quaternion components.

Construct a new SbDPRotation object initialized with the given rotation matrix.

Construct a rotation which is the minimum rotation necessary to make vector rotateFrom point in the direction of vector rotateTo.

Return pointer to an array with the rotation expressed as four quaternion values.

setValue().

Return the four quaternion components representing the rotation.

See also

setValue().

Set the rotation.

See also

getValue().

Return the rotation in the form of an axis-of-rotation and a rotation angle.

See also

setValue().

Return this rotation in the form of a matrix.

See also

setValue().

Invert the rotation. Returns reference to self.

See also

inverse()

Non-destructively inverses the rotation and returns the result.

See also

invert()

Reset the rotation by the four quaternions in the array.

See also

getValue().

Set the rotation from the components of the given matrix. Returns reference to self.

See also

getValue().

Reset rotation with the given axis-of-rotation and rotation angle. Returns reference to self.

Make sure axis is not the null vector when calling this method.

See also

getValue().

Construct a rotation which is the minimum rotation necessary to make vector rotateFrom point in the direction of vector rotateTo.

Returns reference to self.

See also

getValue().

Check the internal quaternion representation vectors for equality within the given tolerance.

Rotate the src vector and put the result in dst.

Scale the angle of rotation by scaleFactor.

Interpolates along the shortest path between the two rotation positions (from rot0 to rot1).

Returns the SbDPRotation which will rotate rot0 the given part t of the spherical distance towards rot1, where t=0 will yield rot0 and t=1 will yield rot1.

t should be in the interval [0, 1].

Returns an identity rotation.

Dump the state of this object to the fp file stream. Only works in debug version of library, method does nothing in an optimized build.

Multiplies the quaternions.

Note that order is important when combining quaternions with the multiplication operator.

Multiplies components of quaternion with scalar value s. Returns reference to self.

Check if the two rotations are equal.

See also

equals().

Check if the two rotations are not equal.

See also

equals().

Multiplies the two rotations and returns the result.

Note that order is important when combining quaternions with the multiplication operator.

Interpolates along the shortest path between the two rotation positions (from rot0 to rot1).

Returns the SbDPRotation which will rotate rot0 the given part t of the spherical distance towards rot1, where t=0 will yield rot0 and t=1 will yield rot1.

t should be in the interval [0, 1].
