Detailed Description

Represents a map of vector data.

Member Function Documentation

VectorString AltusUnified::VectorMapBase::getPolygonHitShapeIds

(

vec2d

point

)

Retrieve the ShapeIds of the polygons below a screen pointl

Parameters

point

Screen space position, in points.

void AltusUnified::VectorMapBase::setDelegate

(

VectorMapDelegate

delegate

)

void AltusUnified::VectorMapBase::setDepthRead

(

BooleanState

depthRead

)

Turns depth testing on or off for this map. When on, vectors can be occluded by other geometry, such as terrain. It is very likely that this should only be changed for maps containing only 3D vectors. 2D vectors can lie below the surface of the Earth sphere and if depth testing is enabled, will not be visible.

void AltusUnified::VectorMapBase::setForce3DLines

(

bool

enabled

)

Promotes all 2D lines and polygon outlines to use the 3D line rendering path, defaults to false;

void AltusUnified::VectorMapBase::setTesselationThreshold

(

double

thresholdInMeters

)

Sets the tesselation threshold for this map, in meters. Lines longer than this threshold are split up.

Parameters

thresholdInMeters

tesselation threshold in meters

void AltusUnified::VectorMapBase::setVectorWindingOrder

(

VectorWindingOrder

windingOrder

)

Sets the vector winding order for this map. Polygons have a front face and a back face and this determines which is which.

Parameters

windingOrder

the winding order of this map, either clockwise or counter-clockwise.

VectorGeometryHit AltusUnified::VectorMapBase::triggerLineHitDetection	(	vec2d	point,
		double	maxPointDistanceToVertex,
		double	maxPointDistanceToLine
	)

Trigger line hit detection on this map (must be called after adding the map to the scene). This returns the hit line/vertex and also calls the map delegate, if set.

Parameters

point	Screen space position, in points.
maxPointDistanceToVertex	the maximum allowable screen space distance between a click and the line vertex for a hit to be registered, in points.
maxPointDistanceToLine	the maximum allowable screen space distance between a click and the line for a hit to be registered, in points.

void AltusUnified::VectorMapBase::updateLineStyle	(	LineStyle	style,
		double	animationDuration
	)

Updates the line style for this map. All lines using this style will be updated

Parameters

animationDuration

The length of time it takes for this change to fully apply, in seconds. (defaults to 0)

void AltusUnified::VectorMapBase::updatePolygonStyle	(	PolygonStyle	style,
		double	animationDuration
	)

Updates the polygon style for this map. All polygons using this style will be updated

Parameters

animationDuration

The length of time it takes for this change to fully apply, in seconds. (defaults to 0)
