* NAME
* Steering Wheel SDK
* COPYRIGHT
* The Logitech Steering Wheel SDK, including all accompanying
* documentation, is protected by intellectual property laws. All
* rights not expressly granted by Logitech are reserved.
* PURPOSE
* The Steering Wheel SDK is an addition to Microsoft's DirectInput
* in DirectX. It is aimed at driving games and enables to
* dramatically shorten development time and improve implementation
* quality for various types of game controllers (USB/gameport
* wheels/joysticks/game pads, FF enabled or not). The Steering Wheel
* SDK has been developed and tested for wheels and joysticks using
* the Logitech, Microsoft and Immersion drivers. It also works with
* Logitech rumble pads (it has not been tested with non-Logitech
* rumble pads). By using the Steering Wheel SDK you have the
* guarantee that all wheels and joysticks will function
* flawlessly. No more situations where force feedback in a game
* behaves very differently from one wheel/joystick to another, which
* in turn results in user frustration and product returns. The
* Steering Wheel SDK comes with a very intuitive and easy to use
* interface which enables to read the wheel/joystick's axes and
* buttons, and also to create all the force feedback effects that
* are necessary for a good and complete implementation. See the
* following files to get started:
* - readme.txt: tells you how to get started.
* - SampleInGameImplementation.cpp: shows line by line how to
* use the Steering Wheel SDK's interface to do a complete
* implementation for PC game controllers in your driving
* game. The idea is to develop support for the steering
* wheel. But if a user plugs in a joystick or game pad he can
* play as well and get force feedback or rumble. If a joystick
* is plugged in, all forces generated by the Steering Wheel
* SDK will be played on the X axis and there will be a
* constant spring on the Y axis.
* - SteeringWheelSDK.cpp: demonstrates force feedback
* effects. Just compile, run and plug in a FF wheel, joystick
* or rumble pad. See usage at top of SteeringWheelSDK.cpp.
* For more details see DirectInput documentation which is part of
* Microsoft's DirectX.

/****f* Steering.Wheel.SDK/GenerateNonLinearValues(INT.index,INT.nonLinCoeff)
* NAME
* HRESULT GenerateNonLinearValues(int index, int nonLinCoeff) --
* Generate non-linear values for the game controller's axis.
* FUNCTION
* Gaming wheels/joysticks/game pads have very different behavior from
* real steering wheels. The reason for single-turn wheels is that
* they only do up to three quarters of a turn lock to lock, compared
* to about 3 turns for a real car.
* This directly affects the steering ratio (15:1 to 20:1 for a real
* car, but only 4:1 for a gaming wheel!). Joysticks and game pads
* have a much shorter range of movement than a real steering wheel as
* well.
* Because of this very short steering ratio or short range, the
* gaming wheel/joystick/game pad will feel highly sensitive which may
* make game play very difficult.
* Especially it may be difficult to drive in a straight line at speed
* (tendency to swerve back and forth).
* One way to get around this problem is to use a sensitivity
* curve. This is a curve that defines the sensitivity of the game
* controller depending on speed. This type of curve is usually used
* for game pads to make up for their low physical range. The result
* of applying such a curve is that at high speed the car's wheels
* will physically turn less than if the car is moving very slowly.
* For example the car's wheels may turn 60 degrees lock to lock at
* low speed but only 10 degrees lock to lock at higher speeds. If
* you calculate the resulting steering ratio for 10 degrees lock to
* lock you find that if you use a steering wheel that turns 180
* degrees lock to lock the ratio is equal to 180/10 = 18, which
* corresponds to a real car's steering ratio.
* If the sensitivity curve has been implemented for the
* wheel/joystick, adding a non-linear curve probably is not
* necessary. But you may find that even after applying a sensitivity
* curve, the car still feels a little twitchy on a straight line when
* driving fast. This may be because in your game you need more than
* 10 degrees lock to lock even at high speeds. Or maybe the car is
* moving at very high speeds where even a normal steering ratio is
* not good enough to eliminate high sensitivity.
* The best way at this point is to add a non-linear curve on top of
* the sensitivity curve.
* The effect of the non-linear curve with positive nonLinCoeff is
* that around center position the wheel/joystick will be less
* sensitive. Yet at locked position left or right the car's wheels
* will turn the same amount of degrees as without the non-linear
* response curve. Therefore the car will become more controllable on
* a straight line and game-play will be improved.
* There can sometimes be cases where the wheel does not feel
* sensitive enough. In that case it is possible to add a non-linear
* curve with the inverse effect (makes the steering more sensitive
* around center position) by using negative values for
* nonLinCoeff. This method lets you define a non-linearity
* coefficient which will determine how strongly non-linear the curve
* will be. When running the method it will generate a mapping table
* in the form of an array. For each of the 1024 entries in this array
* there will be a corresponding non-linear value which can be used as
* the wheel/joystick's axis position instead of the original
* value. See Sample_In-game_Implementation.cs for an example.
* INPUTS
* index - index to which the concerned game controller is connected.
* Index 0 corresponds to the first game controller connected. Index 1
* to the second game controller.
*
* nonLinCoeff - value representing how much non-linearity should be
* applied. Range is -100 to 100. 0 = linear curve, 100 = maximum
* non-linear curve with less sensitivity around center, -100 =
* maximum non-linearity with more sensitivity around center position.
* RETURN VALUE
* S_OK if successful, E_FAIL otherwise.

* FUNCTION
* A constant force works best when continuously updated with a value
* tied to the physics engine.
* Tie the steering wheel/joystick to the car's physics engine via a
* vector force. This will create a centering spring effect, a sliding
* effect, a feeling for the car's inertia, and depending on the
* physics engine it should also give side collisions (wheel/joystick
* jerks in the opposite way of the wall the car just touched).
* The vector force could for example be calculated from the lateral
* force measured at the front tires. This vector force should be 0
* when at a stop or driving straight. When driving through a turn or
* when driving on a banked surface the vector force should have a
* magnitude that grows in a proportional way.
* INPUTS
* index - index of the game controller. Index 0 corresponds to the
* first wheel/joystick connected. Index 1 to the second
* wheel/joystick.
*

*
* type - Specifies the type of force effect. Can be one of the
* following values:
* - PeriodicType.LG_TYPE_SINE
* - PeriodicType.LG_TYPE_SQUARE
*
* magnitudePercentage - Specifies the magnitude of the surface
* effect. Valid ranges for magnitudePercentage are 0 to 100. Values
* higher than 100 are silently clamped.
*
* period - Specifies the period of the periodic force effect. The
* value is the duration for one full cycle of the periodic function
* measured in milliseconds. A good range of values for the period is
* 20 ms (sand) to 120 ms (wooden bridge or cobblestones). For a
* surface effect the period should not be any bigger than 150 ms.
