QgsLine3DSymbol class

3 3D symbol that draws linestring geometries as planar polygons (created from lines using a buffer with given thickness).

Base classes

class QgsAbstract3DSymbol

3 Abstract base class for 3D symbols that are used by VectorLayer3DRenderer objects.

Constructors, destructors, conversion operators

QgsLine3DSymbol() defaulted

Constructor for QgsLine3DSymbol.

Public functions

auto altitudeBinding() const -> Qgs3DTypes::AltitudeBinding

Returns method that determines how altitude is bound to individual vertices.

auto altitudeClamping() const -> Qgs3DTypes::AltitudeClamping

Returns method that determines altitude (whether to clamp to feature to terrain)

auto clone() const -> QgsAbstract3DSymbol* override

Returns a new instance of the symbol with the same settings.

auto extrusionHeight() const -> float

Returns extrusion height (in map units)

auto height() const -> float

Returns height (altitude) of the symbol (in map units)

auto material() const -> QgsPhongMaterialSettings

Returns material used for shading of the symbol.

void readXml(const QDomElement& elem, const QgsReadWriteContext& context) override

Reads symbol configuration from the given DOM element.

auto renderAsSimpleLines() const -> bool

Returns whether the renderer will render data with simple lines (otherwise it uses buffer)

void setAltitudeBinding(Qgs3DTypes::AltitudeBinding altBinding)

Sets method that determines how altitude is bound to individual vertices.

void setAltitudeClamping(Qgs3DTypes::AltitudeClamping altClamping)

Sets method that determines altitude (whether to clamp to feature to terrain)

void setExtrusionHeight(float extrusionHeight)

Sets extrusion height (in map units)

void setHeight(float height)

Sets height (altitude) of the symbol (in map units)

void setMaterial(const QgsPhongMaterialSettings& material)

Sets material used for shading of the symbol.

void setRenderAsSimpleLines(bool enabled)

Sets whether the renderer will render data with simple lines (otherwise it uses buffer)

void setWidth(float width)

Sets width of the line symbol (in map units)

auto type() const -> QString override

Returns identifier of symbol type. Each 3D symbol implementation should return a different type.

auto width() const -> float

Returns width of the line symbol (in map units)

void writeXml(QDomElement& elem, const QgsReadWriteContext& context) const override

Writes symbol configuration to the given DOM element.
