virtual bool DtRailPathMetric::init

(

)

[virtual]

Call immediately after constructor.

Reimplemented from DtPathMetric.

virtual double DtRailPathMetric::transitionCost	(	const DtPoint &	startPoint,
		const DtPoint &	endPoint
	)		const [virtual]

Just returns the distance between points.

Implements DtPathMetric.

virtual double DtRailPathMetric::transitionCost	(	const DtPoint &	startPoint,
		DtNetworkEdge *	edge
	)		[virtual]

Just returns the length of the edge.

virtual double DtRailPathMetric::turningCost

(

double

cosAngle

)

const [virtual]

Returns a cost based on the turning radius of the vehicle.

Implements DtPathMetric.

virtual double DtRailPathMetric::multiplierForPoint

(

const DtPoint &

point

)

const [virtual]

Override this function to add your own cost calculations to the path.

Default implementation return 1.0. To further customize this metric, override this method and return a multiplier for each point. Do not return less than 1.0 in order to keep the optimistic heuristic rule.
