Cylinder2DWrapper	(	Arena *	arena,
		PhyCylinder *	cylinder,
		Type	type
	)

protected

Constructor.

Parameters

arena	the arena in which this object lives
cylinder	the cylinder to wrap
type	the type of cylinder. This can only be one of Cylinder, SmallCylinder, BigCylinder or CircularTargetArea. If the type is CircularTargetArea, this cannot be made non-static

Member Function Documentation

bool computeDistanceAndOrientationFromRobot	(	const WheeledRobot2DWrapper &	robot,
		double &	distance,
		double &	angle
	)		const

virtual

Computes the distance and orientation of this object respect to the given robot.

This function computes the distance of this object from the given robot. The distance is computed between the nearest points of the two objects. The robot is always modelled as a vertical cylindrical object. The function returns false if it makes no sense to compute the distance

Parameters

robot	the robot from which the distance should be computed
distance	the computed distance
angle	the computed orientation

Returns: false if the distance couldn't be computed

Implements PhyObject2DWrapper.

void computeLinearViewFieldOccupiedRange	(	const wMatrix &	cameraMtr,
		double &	minAngle,
		double &	maxAngle,
		double &	distance
	)		const

virtual

Computes the portion of a linear the view field occupied by this object.

This function returns the angular range occupied by this object on a linear camera described by the given matrix. The Z axis of the matrix is the upvector, the camera lies on the XY plane and points towars the X axis (i.e. angles start from the X axis). If the object is not visible by the camera, this function returns a negative distance. The min angle can be greater than the max angle if the object is behind the camera. Here we make the assumption that the camera is outside the object (otherwise the algorithm gives wrong results). The matrix representing the camera is translated so that it is on the same plane as the lower base of the object before doing computations

Parameters

cameraMtr	the matrix describing the camera (see function description)
minAngle	this is set to the minimum angle of the view field occupied by the object
maxAngle	this is set to the maximum angle of the view field occupied by the object
distance	this is set to the distance of the object from the camera. It is negative if the object is not visible by the camera

PhyCylinder * phyObject ( )

virtual

Returns a pointer to the wrapped PhyObject.

You should avoid changing the PhyObject directly, use the methods of this class, instead
