Detailed Description

QLayer works in conjunction with the QLayerFilter in the FrameGraph.

A QLayer can be applied to a subtree of entities by setting the recursive property to true.

 #include <Qt3DCore/QEntity>
 #include <Qt3DRender/QGeometryRenderer>
 #include <Qt3DRender/QLayer>
 #include <Qt3DRender/QLayerFilter>
 #include <Qt3DRender/QViewport>

// Scene
Qt3DCore::QEntity *rootEntity = new Qt3DCore::Qt3DCore::QEntity;

Qt3DCore::QEntity *renderableEntity = new Qt3DCore::Qt3DCore::QEntity(rootEntity);
Qt3DRender::QGeometryRenderer *geometryRenderer = new Qt3DCore::QGeometryRenderer(renderableEntity);
Qt3DRender::QLayer *layer1 = new Qt3DCore::QLayer(renderableEntity);
layer1->setRecursive(true);
renderableEntity->addComponent(geometryRenderer);
renderableEntity->addComponent(layer1);

...

// FrameGraph
Qt3DRender::QViewport *viewport = new Qt3DRender::QViewport;
Qt3DRender::QLayerFilter *layerFilter = new Qt3DRender::QLayerFilter(viewport);
layerFilter->addLayer(layer1);
