Detailed Description

3 Off-screen 3D engine implementation.

It is useful for recording rendered 3D scenes of arbitrary size.

Note

While the on-screen 3D engine also allows capturing of images, its limitation is that the captured images are of the size of the on-screen window.

Member Function Documentation

camera()

Qt3DRender::QCamera * QgsOffscreen3DEngine::camera ( )

overridevirtual

Returns pointer to the engine's camera entity.

Implements QgsAbstract3DEngine.

Definition at line 222 of file qgsoffscreen3dengine.cpp.

renderSettings()

Qt3DRender::QRenderSettings * QgsOffscreen3DEngine::renderSettings ( )

overridevirtual

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

Implements QgsAbstract3DEngine.

Definition at line 217 of file qgsoffscreen3dengine.cpp.

requestCaptureImage()

void QgsOffscreen3DEngine::requestCaptureImage ( )

overridevirtual

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.

Implements QgsAbstract3DEngine.

Definition at line 232 of file qgsoffscreen3dengine.cpp.

setClearColor()

void QgsOffscreen3DEngine::setClearColor ( const QColor &  color )

overridevirtual

Sets background color of the scene.

Implements QgsAbstract3DEngine.

Definition at line 117 of file qgsoffscreen3dengine.cpp.

setFrustumCullingEnabled()

void QgsOffscreen3DEngine::setFrustumCullingEnabled ( bool  enabled )

overridevirtual

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

Implements QgsAbstract3DEngine.

Definition at line 122 of file qgsoffscreen3dengine.cpp.

setRootEntity()

void QgsOffscreen3DEngine::setRootEntity ( Qt3DCore::QEntity *  root )

overridevirtual

Sets root entity of the 3D scene.

Implements QgsAbstract3DEngine.

Definition at line 204 of file qgsoffscreen3dengine.cpp.

setSize()

void QgsOffscreen3DEngine::setSize

(

QSize

s

)

Sets the size of the rendering area (in pixels)

Definition at line 106 of file qgsoffscreen3dengine.cpp.

size()

QSize QgsOffscreen3DEngine::size ( ) const

overridevirtual

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

Implements QgsAbstract3DEngine.

Definition at line 227 of file qgsoffscreen3dengine.cpp.
