Methods

GetExtent(Double)

Gets the 3-dimensional extent of an object

Declaration

BoundingCube GetExtent(double precision)

Parameters

Type	Name	Description
System.Double	precision	Precision of the test

Returns

Type	Description
BoundingCube	The minmax cube

HitTest(ref BoundingCube, Double)

Tests whether an object is touched by the provided cube

Declaration

bool HitTest(ref BoundingCube cube, double precision)

Parameters

Type	Name	Description
BoundingCube	cube	To test with
System.Double	precision	Required precision

Returns

Type	Description
System.Boolean	true if the object strikes the cube

HitTest(Projection, BoundingRect, Boolean)

Tests whether an object is inside or touched by the rectangle when projected with the provided projection

Declaration

bool HitTest(Projection projection, BoundingRect rect, bool onlyInside)

Parameters

Type	Name	Description
Projection	projection	The projection for the test
BoundingRect	rect	The rectangle to test the position
System.Boolean	onlyInside	true: the object must be totaly inside the rectangle, false: the object must be totaly or partially inside the rectangle

Returns

Type	Description
System.Boolean	true when the test succeedes, false otherwise

HitTest(Projection.PickArea, Boolean)

Tests whether an object is inside or touched by the provided area

Declaration

bool HitTest(Projection.PickArea area, bool onlyInside)

Parameters

Type	Name	Description
Projection.PickArea	area	The area to check for
System.Boolean	onlyInside	true: the object must be totaly inside the area, false: the object must be totaly or partially inside the area

Returns

Type	Description
System.Boolean	true when the test succeedes, false otherwise

Position(GeoPoint, GeoVector, Double)

Returns the smallest parameter value (l) where the provided line hits the object so that the point fromHere + l * direction is on or close to the object. The result may be negative. Return double.MaxValue if there is no such point.

Declaration

double Position(GeoPoint fromHere, GeoVector direction, double precision)

Parameters

Type	Name	Description
GeoPoint	fromHere	Startpoint of the line
GeoVector	direction	Direction of the line
System.Double	precision	Precision for the test

Returns

Type	Description
System.Double	Position on the line
