   "A camera is typically manipulated by a GameConnection.  When set as the connection's "
   "control object, the camera handles all movement actions ($mvForwardAction, $mvPitch, etc.) "
   "just like a Player.\n"

   "<h3>Methods of Operation</h3>\n\n"

   "The camera has two general methods of operation.  The first is the standard mode where "
   "the camera starts and stops its motion and rotation instantly.  This is the default operation "
   "of the camera and is used by most games.  It may be specifically set with Camera::setFlyMode() "
   "for 6 DoF motion.  It is also typically the method used with Camera::setOrbitMode() or one of "
   "its helper methods to orbit about a specific object (such as the Player's dead body) or a "
   "specific point.\n\n"

   "The second method goes under the name of Newton as it follows Newton's 2nd law of "
   "motion: F=ma.  This provides the camera with an ease-in and ease-out feel for both movement "
   "and rotation.  To activate this method for movement, either use Camera::setNewtonFlyMode() or set "
   "the Camera::newtonMode field to true.  To activate this method for rotation, set the Camera::newtonRotation "
   "to true.  This method of operation is not typically used in games, and was developed to allow "
   "for a smooth fly through of a game level while recording a demo video.  But with the right force "
   "and drag settings, it may give a more organic feel to the camera to games that use an overhead view, "
   "such as a RTS.\n\n"

   "There is a third, minor method of operation but it is not generally used for games.  This is when the "
   "camera is used with Torque's World Editor in Edit Orbit Mode.  When set, this allows the camera "
   "to rotate about a specific point in the world, and move towards and away from this point.  See "
   "Camera::setEditOrbitMode() and Camera::setEditOrbitPoint().  While in this mode, Camera::autoFitRadius() "
   "may also be used.\n\n"

   "<h3>Motion Modes</h3>\n\n"

   "Beyond the different operation methods, the Camera may be set to one of a number "
   "of motion modes.  These motion modes determine how the camera will respond to input "
   "and may be used to constrain how the Camera moves.  The CameraMotionMode enumeration "
   "defines the possible set of modes and the Camera's current may be obtained by using "
   "getMode().\n\n"

   "Some of the motion modes may be set using specific script methods.  These often provide "
   "additional parameters to set up the mode in one go.  Otherwise, it is always possible to "
   "set a Camera's motion mode using the controlMode property.  Just pass in the name of the "
   "mode enum.  The following table lists the motion modes, how to set them up, and what they offer:\n\n"

   "<table border='1' cellpadding='1'>"
   "<tr><th>Mode</th><th>Set From Script</th><th>Input Move</th><th>Input Rotate</th><th>Can Use Newton Mode?</th></tr>"
   "<tr><td>Stationary</td><td>controlMode property</td><td>No</td><td>No</td><td>No</td></tr>"
   "<tr><td>FreeRotate</td><td>controlMode property</td><td>No</td><td>Yes</td><td>Rotate Only</td></tr>"
   "<tr><td>Fly</td><td>setFlyMode()</td><td>Yes</td><td>Yes</td><td>Yes</td></tr>"
   "<tr><td>OrbitObject</td><td>setOrbitMode()</td><td>Orbits object</td><td>Points to object</td><td>Move only</td></tr>"
   "<tr><td>OrbitPoint</td><td>setOrbitPoint()</td><td>Orbits point</td><td>Points to location</td><td>Move only</td></tr>"
   "<tr><td>TrackObject</td><td>setTrackObject()</td><td>No</td><td>Points to object</td><td>Yes</td></tr>"
   "<tr><td>Overhead</td><td>controlMode property</td><td>Yes</td><td>No</td><td>Yes</td></tr>"
   "<tr><td>EditOrbit (object selected)</td><td>setEditOrbitMode()</td><td>Orbits object</td><td>Points to object</td><td>Move only</td></tr>"
   "<tr><td>EditOrbit (no object)</td><td>setEditOrbitMode()</td><td>Yes</td><td>Yes</td><td>Yes</td></tr>"
   "</table>\n\n"

   "<h3>%Trigger Input</h3>\n\n"

   "Passing a move trigger ($mvTriggerCount0, $mvTriggerCount1, etc.) on to a Camera performs "
   "different actions depending on which mode the camera is in.  While in Fly, Overhead or "
   "EditOrbit mode, either trigger0 or trigger1 will cause a camera to move twice its normal "
   "movement speed.  You can see this in action within the World Editor, where holding down the "
   "left mouse button while in mouse look mode (right mouse button is also down) causes the Camera "
   "to move faster.\n\n"

   "Passing along trigger2 will put the camera into strafe mode.  While in this mode a Fly, "
   "FreeRotate or Overhead Camera will not rotate from the move input.  Instead the yaw motion "
   "will be applied to the Camera's x motion, and the pitch motion will be applied to the Camera's "
   "z motion.  You can see this in action within the World Editor where holding down the middle mouse "
   "button allows the user to move the camera up, down and side-to-side.\n\n"

   "While the camera is operating in Newton Mode, trigger0 and trigger1 behave slightly differently.  "
   "Here trigger0 activates a multiplier to the applied acceleration force as defined by speedMultiplier.  "
   "This has the affect of making the camera move up to speed faster.  trigger1 has the opposite affect "
   "by acting as a brake.  When trigger1 is active a multiplier is added to the Camera's drag as "
   "defined by brakeMultiplier.\n\n"
