Detailed Description

This class is subject to change. Programs using this class may require changes with a new version of VirtualLab.
Class which describes a rectangular region which may be situated at an arbitrary center and which may be rotated by an arbitrary angle.

Constructor & Destructor Documentation

RectangularRegion() [1/3]

RectangularRegion	(	VectorD	location,
		double	width,
		double	height,
		double	angle,
		bool	bottomLeftCoordinateInsteadOfCenterGiven,
		bool	boundaryIsInside = false,
		PhysicalProperty	propertyOfCoordinatesX = PhysicalProperty::Length,
		PhysicalProperty	propertyOfCoordinatesY = PhysicalProperty::Length )

Constructor with all field parameters.

Parameters

location	The center of the rectangle in case bottomLeftCoordinateInsteadOfCenterGiven == false. Otherwise this parameter gives the bottom left corner.
width	Width of the rectangle.
height	Height of the rectangle.
angle	Rotation angle (in radians) of the rectangle: The rotation is done about the given location. The angle is defined between the width-side and the x-axis, as well as between the height-side and the y-axis.
bottomLeftCoordinateInsteadOfCenterGiven	If true, the first parameter is not the center but the bottom left corner of the unrotated rectangle. Important: The rotation by angle is done around the location, no matter if it is the center or not.
boundaryIsInside	Flag which says whether or not the boundary is part of the inner region or not.
propertyOfCoordinatesX	Physical property of the x-coordinate.
propertyOfCoordinatesY	Physical property of the y-coordinate.

RectangularRegion() [2/3]

RectangularRegion

RectangularRegion() [3/3]

RectangularRegion	(	RectanglePhysical	rectangle,
		bool	boundariesAreInside )

Constructor which creates region from RectanglePhysical.

Parameters

rectangle	RectanglePhysical to be represented as region.
boundariesAreInside	If true, values lying exactly on the boundaries are considered as being 'inside' the region.

DeserializationPostProcessing()

new void DeserializationPostProcessing	(	ref List< System.Reflection.FieldInfo >	unfindableFields,
