)

[protected, virtual]

Calculates the amount of deceleration caused by movement over the current soil type.

virtual void DtAutomotiveActuatorComponent::calculateOrientationAndPosition	(	const DtVector &	newLocalProjectedLocation,
		double	newHeading,
		DtDcm &	newLocalOrientation,
		DtVector &	newLocalPosition
	)		[protected, virtual]

Calculates the orientation and position of the entity, given a new location and heading.

Checks for intersections with the terrain, to determine altitude and orientation (from support points) from 1/4 of the height of the entity's bounding volume as a rough approximation of the entity's wheel's or tread (or knees).

Returns:

nothing, but sets the specified orientation and position appropriately.

Note:

As a side effect, this also fills in the soil type, position, and altitude information of the groundCenter of the vrfObject. This is done through the placePoints() call from the state repository.

virtual bool DtAutomotiveActuatorComponent::useHighFidelityGroundClamping

(

)

const [protected, virtual]

Returns:

a boolean signifying whether or not to use high fidelity ground clamping when calculating the orientation of the entity.

Note:

		const DtVector &	location,
		DtAttachedTerrain &	terrain,
		DtVector &	newNormal
	)		[protected]

Clamps the entity to the ground at the specified location, and determines the normal of the plane the entity is on at that location.

Returns:

a boolean indicating success or failure in performing the ground clamping and determining the new normal.

Note:

As a side effect of this function, the soil type in the center ground interaction point is set.

The type of ground clamping also depends on the entity's configuration. Either high or low fidelity ground clamping is performed as specified.

See also:

groundClampHighFidelity

groundClampLowFidelity

void DtAutomotiveActuatorComponent::groundClampHighFidelity	(	double	heading,
		const DtVector &	location,
		DtAttachedTerrain &	terrain,
		DtVector &	newNormal
	)		[protected]

Uses all four ground interaction points to determine the plane of the entity and the soil type.

The left, right, and other support points are used to determine the plane, and the returned normal is the normal to that plane.

void DtAutomotiveActuatorComponent::groundClampLowFidelity	(	double	heading,
		const DtVector &	location,
		DtAttachedTerrain &	terrain,
		DtVector &	newNormal
	)		[protected]

Uses only the center ground interaction point.

The normal is the normal of the polygon on which the center point sits. And the soil type is also the polygon's. This requires fewer intersection tests with the terrain, but also may return an incorrect normal if the entity is sitting across several polygons.

virtual double DtAutomotiveActuatorComponent::calculateHeading	(	double	oldHeading,
		const DtVector &	oldBodyVelocity,
		DtAutoTransmissionGear	gear,
		double	steering,
		double	throttle,
		double	dT
	)		[protected, virtual]

Determines the new heading given the old heading, the velocity, gear, steering, throttle, and time delta.

Returns:

The new heading value.

virtual DtVector DtAutomotiveActuatorComponent::calculateBodyAcceleration	(	double	throttle,
		DtAutoTransmissionGear	gear,
		double	brake,

Calls following functions for components of the acceleration: calculateAccelerationFromEngine() calculateAccelerationFromSlope() calculateMaxDecelerationFromFriction() calculateMaxDecelerationFromBrake()

virtual DtVector DtAutomotiveActuatorComponent::calculateBodyVelocity	(	const DtVector &	oldBodyVelocity,
		const DtVector &	newBodyAcceleration,
		double	dT
	)		[protected, virtual]

		const DtVector &	newBodyAcceleration,
		const DtVector &	oldBodyVelocity,
		double	newHeading
	)		[protected, virtual]

virtual bool DtAutomotiveActuatorComponent::checkForTerrainCollisions

(

)

const [protected, virtual]

Returns:

a boolean signifying whether or not the terrain should be checked for collisions with the entity's bounding volume while it moves. If this returns true, the entity will not move through the terrain. If this is false, it may move through terrain polygons, such as building walls when moving to a new location.

Note:

it currently just returns the value of the user specified parameter in the automotivePSR.

virtual bool DtAutomotiveActuatorComponent::foundTerrainCollision	(	double	heading,
		const DtVector &	oldLocalPosition,
		const DtVector &	newLocalPosition,
		DtChordIntersectionRecord &	collisionIntersectionRecord
	)		const [protected, virtual]

Checks the terrain in between the specified old and new positions, along the specified heading for any terrain intersections.

Returns:

a boolean signifying whether or not a terrain collision was found. If so, a valid intersection record is returned in the user specified intersection record.

virtual bool DtAutomotiveActuatorComponent::createMovementChord	(	DtChord &	movementChord,
		double	heading,
		const DtVector &	oldLocalPosition,
		const DtVector &	newLocalPosition
	)		const [protected, virtual]

Creates a chord along the specified heading, starting at the old position and ending at the new position, but each location is increased by the half height of the entity so that the check is done along the center of the entity's movement.

Additionally, the chord is extended in the heading direction by the half-length of the entity to ensure that collision with the front of the entity and not just the center, are detected.

Returns:

a boolean signifying whether or not the chord could be created.

Note:

Returns a valid chord in movementChord only if the return value is true.

virtual bool DtAutomotiveActuatorComponent::terrainPassable	(	double	heading,
		const DtChordIntersectionRecord &	terrainIntersectionRecord
	)		const [protected, virtual]

Determines if the terrain referenced in the intersection record is "passable" by the entity.

Currently, just looks at the slope of the terrain. If the slope is greater than 80 degrees, the terrain is considered impassable.

virtual double DtAutomotiveActuatorComponent::calculateMaxSpeed

(

)

[protected, virtual]

Calculates the maximum speed for the entity, considering soil factors.

virtual double DtAutomotiveActuatorComponent::calculateMaxAcceleration

(

		const DtDcm &	oldOrientation,
		double	dT
	)		[protected, virtual]

Calculates rotational velocity from new and old orientation body DCMs.

Thich coordinate system is used shouldn't make a difference so long as the coordinate system is orthographic and consistent.

virtual double DtAutomotiveActuatorComponent::calculatePitch	(	const DtVector &	localPosition,
		double	heading,
		const DtAttachedTerrain &	terrain
	)		[protected, virtual]

Calculates pitch at given local position and given heading.

virtual void DtAutomotiveActuatorComponent::calculateDirectionOfLinearMotion	(	const DtDcm &	newLocalOrientation,
		const DtVector &	newLocalPosition,
		DtDcm &	newLocalDirectionOfLinearMotion
	)		[protected, virtual]

Computes direction of linear motion.

In base class, this is equivalent to newLocalOrientation, so it sets newLocalDirectionOfLinearMotion = newLocalOrientation.

virtual double DtAutomotiveActuatorComponent::getPitchAdjustedMaxSpeed	(	double	maxSpeed,
		double	pitch
	)		const [protected, virtual]

Computes a new maximum speed, adjusted for the current pitch of the entity.

If the pitch is less than zero 1.2 * maxSpeed is returned. For pitch >= 0, the original maxSpeed is returned.
