  * @brief Constraint function to aim a camera at a target.

- * Constraint which sets camera's rotation given camera world position
+ * Constraint which sets camera's orientation given camera world position
  * and a target world position.  Uses target's up vector to orient the
  * constrained actor along the vector between camera position and
  * target position.
  *
- * @param[in] current The current rotation property value
+ * @param[in] current The current orientation property value
  * @param[in] targetPosition World position of target
  * @param[in] cameraPosition World position of camera
- * @param[in] targetRotation World rotation of the target
+ * @param[in] targetOrientation World orientation of the target
  * @return The orientation of the camera
