Member Function Documentation

◆ clone()

QgsTiledSceneRenderer * QgsTiledSceneTextureRenderer::clone ( ) const

overridevirtual

Create a deep copy of this renderer.

Should be implemented by all subclasses and generate a proper subclass.

Implements QgsTiledSceneRenderer.

Definition at line 35 of file qgstiledscenetexturerenderer.cpp.

◆ create()

QgsTiledSceneRenderer * QgsTiledSceneTextureRenderer::create	(	QDomElement &	element,
		const QgsReadWriteContext &	context
	)

static

Creates a textured renderer from an XML element.

Definition at line 45 of file qgstiledscenetexturerenderer.cpp.

◆ createDefaultFillSymbol()

QgsFillSymbol * QgsTiledSceneTextureRenderer::createDefaultFillSymbol ( )

static

Returns a copy of the default fill symbol used to render triangles without textures.

See also: setFillSymbol()

Definition at line 64 of file qgstiledscenetexturerenderer.cpp.

◆ fillSymbol()

QgsFillSymbol * QgsTiledSceneTextureRenderer::fillSymbol ( ) const

Returns the fill symbol used to render triangles without textures.

See also: setFillSymbol()

Definition at line 77 of file qgstiledscenetexturerenderer.cpp.

◆ flags()

Qgis::TiledSceneRendererFlags QgsTiledSceneTextureRenderer::flags ( ) const

overridevirtual

Returns flags which control how the renderer behaves.

Reimplemented from QgsTiledSceneRenderer.

Definition at line 108 of file qgstiledscenetexturerenderer.cpp.

◆ renderLine()

void QgsTiledSceneTextureRenderer::renderLine	(	QgsTiledSceneRenderContext &	context,
		const QPolygonF &	line
	)

overridevirtual

Renders a line.

Implements QgsTiledSceneRenderer.

Definition at line 256 of file qgstiledscenetexturerenderer.cpp.

◆ renderTriangle()

void QgsTiledSceneTextureRenderer::renderTriangle	(	QgsTiledSceneRenderContext &	context,
		const QPolygonF &	triangle
	)

overridevirtual

Renders a triangle.

Implements QgsTiledSceneRenderer.

Definition at line 118 of file qgstiledscenetexturerenderer.cpp.

◆ save()

QDomElement QgsTiledSceneTextureRenderer::save	(	QDomDocument &	doc,
		const QgsReadWriteContext &	context
	)		const

overridevirtual

Saves the renderer configuration to an XML element.

See also: load()

Implements QgsTiledSceneRenderer.

Definition at line 87 of file qgstiledscenetexturerenderer.cpp.

◆ setFillSymbol()

void QgsTiledSceneTextureRenderer::setFillSymbol ( QgsFillSymbol * symbol )

Sets the fill symbol used to render triangles without textures.

Ownership of symbol is transferred.

See also: fillSymbol()

Definition at line 82 of file qgstiledscenetexturerenderer.cpp.

◆ startRender()

void QgsTiledSceneTextureRenderer::startRender ( QgsTiledSceneRenderContext & context )

overridevirtual

Must be called when a new render cycle is started.

A call to startRender() must always be followed by a corresponding call to stopRender() after all features have been rendered.

See also: stopRender()

Warning: This method is not thread safe. Before calling startRender() in a non-main thread, the renderer should instead be cloned and startRender()/stopRender() called on the clone.

Reimplemented from QgsTiledSceneRenderer.

Definition at line 261 of file qgstiledscenetexturerenderer.cpp.

◆ stopRender()

void QgsTiledSceneTextureRenderer::stopRender ( QgsTiledSceneRenderContext & context )

overridevirtual

Must be called when a render cycle has finished, to allow the renderer to clean up.

Calls to stopRender() must always be preceded by a call to startRender().

Warning: This method is not thread safe. Before calling startRender() in a non-main thread, the renderer should instead be cloned and startRender()/stopRender() called on the clone.

See also: startRender()

Reimplemented from QgsTiledSceneRenderer.

Definition at line 267 of file qgstiledscenetexturerenderer.cpp.

◆ type()

QString QgsTiledSceneTextureRenderer::type ( ) const

overridevirtual

Returns the identifier of the renderer type.

Implements QgsTiledSceneRenderer.

Definition at line 30 of file qgstiledscenetexturerenderer.cpp.
