Method Detail

• {Object} getAxisAngle()
  Returns the Rotation in Axis Angle representation

  Returns:

  {Object} Object with axis and angle information e.g. {axis: arel.Vetor3D, angle: angleRad}
• {arel.Vector3D} getEulerAngleDegrees()
  Returns the Rotation in Euler representation

  Returns:

  {arel.Vector3D} Euler rotation values in degrees
• {arel.Vector3D} getEulerAngleRadians()
  Returns the Rotation in Euler representation

  Returns:

  {arel.Vector3D} Euler rotation values in radians
• {Array} getMatrix()
  Returns the Rotation in Matrix representation

  Returns:

  {Array} 3x3 rotationMatrix in row-major order
• {arel.Rotation} inverse()
  Returns an inverted copy of this rotation. This inverse corresponds to a rotation in the opposite direction rotation*rotation.inverse() == no Rotation

  Returns:

  {arel.Rotation} The inverse of the rotation
• setFromAxisAngle(axis, angle)
  Creates the Rotation from Axis Angle representation

  Parameters:

  {arel.Vector3D} axis

  the axis

  {Number} angle

  in radians *
• setFromEulerAngleDegrees(vec3D)
  Creates the Rotation from Euler representation in degree (order: x-y-z)

  Parameters:

  {arel.Vector3D} vec3D

  Euler rotation values in degree
• setFromEulerAngleRadians(vec3D)
  Creates the Rotation from Euler representation in Radians (order: x-y-z)

  Parameters:

  {arel.Vector3D} vec3D

  Euler rotation values in radians
• setFromMatrix(rotationMatrix)
  Creates an arel.Rotation Object from Matrix (3x3) representation (row major order)

  Parameters:

  {Array} rotationMatrix

  3x3 rotationMatrix in row-major order
