Constructor.

Parameters

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

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 wall (otherwise the algorithm gives wrong results). The matrix representing the camera is translated so that it is on the same plane as the vertexes of the wall 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

Implements PhyObject2DWrapper.
