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.

Syntax
public struct SbRotationd

The SbRotationd type exposes the following members.

Constructors
  NameDescription
Public methodSbRotationd(Double)
Constructor for rotation.
Public methodSbRotationd(SbMatrixd)
Constructor for rotation.
Public methodSbRotationd(SbMatrixd)
Constructor for rotation.
Public methodSbRotationd(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.
Public methodSbRotationd(SbVec3d, Double)
Constructor for rotation. The axis/radians constructor creates a rotation of angle radians about the given axis.
Public methodSbRotationd(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.
Public methodSbRotationd(SbVec3d, Double)
Constructor for rotation. The axis/radians constructor creates a rotation of angle radians about the given axis.
Public methodSbRotationd(Double, Double, Double, Double)
Constructor for rotation.
