Detailed Description

3 Base class for 3D engine implementation.

A 3D engine is responsible for setting up rendering with Qt3D. This means mainly:

We have two implementations:

Member Function Documentation

◆ camera()

virtual Qt3DRender::QCamera* QgsAbstract3DEngine::camera ( )
pure virtual

Returns pointer to the engine's camera entity.

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ imageCaptured

void QgsAbstract3DEngine::imageCaptured ( const QImage &  image)
signal

Emitted after a call to requestCaptureImage() to return the captured image.

◆ renderSettings()

virtual Qt3DRender::QRenderSettings* QgsAbstract3DEngine::renderSettings ( )
pure virtual

Returns access to the engine's render settings (the frame graph can be accessed from here)

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ requestCaptureImage()

virtual void QgsAbstract3DEngine::requestCaptureImage ( )
pure virtual

Starts a request for an image rendered by the engine.

The function does not block - when the rendered image is captured, it is returned in imageCaptured() signal. Only one image request can be active at a time.

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ setClearColor()

virtual void QgsAbstract3DEngine::setClearColor ( const QColor &  color)
pure virtual

Sets background color of the scene.

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ setFrustumCullingEnabled()

virtual void QgsAbstract3DEngine::setFrustumCullingEnabled ( bool  enabled)
pure virtual

Sets whether frustum culling is enabled (this should make rendering faster by not rendering entities outside of camera's view)

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ setRootEntity()

virtual void QgsAbstract3DEngine::setRootEntity ( Qt3DCore::QEntity *  root)
pure virtual

Sets root entity of the 3D scene.

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.

◆ size()

virtual QSize QgsAbstract3DEngine::size ( ) const
pure virtual

Returns size of the engine's rendering area in pixels.

Implemented in QgsOffscreen3DEngine, and QgsWindow3DEngine.
