詳細描述

This class is rarely instanced directly since it doesn't provide any frame graph specific behavior, although it can be convenient to use for grouping other nodes together in dynamic frame graphs. The actual behavior comes from the subclasses.

The subclasses are:

class	描述
Qt3DRender::QCameraSelector	Select camera from all available cameras in the scene
Qt3DRender::QClearBuffers	Specify which buffers to clear and to what values
Qt3DRender::QDispatchCompute	Specify Compute operation kernels
Qt3DRender::QFrustumCulling	Enable frustum culling
Qt3DRender::QLayerFilter	Select which layers to draw
Qt3DRender::QNoDraw	Disable drawing
Qt3DRender::QRenderPassFilter	Select which render passes to draw
Qt3DRender::QRenderStateSet	Set render states
Qt3DRender::QRenderSurfaceSelector	Select which surface to draw to
Qt3DRender::QRenderTargetSelector	Select which QRenderTarget to draw to
Qt3DRender::QSortPolicy	Specify how entities are sorted to determine draw order
Qt3DRender::QTechniqueFilter	Select which techniques to draw
Qt3DRender::QViewport	Specify viewport
Qt3DRender::QMemoryBarrier	Places a memory barrier

QFrameGraphNode:: QFrameGraphNode ( Qt3DCore::QNode * parent = nullptr)

構造函數創建實例，采用指定的 parent .

Qt3DRender::QFrameGraphNode *QFrameGraphNode:: parentFrameGraphNode () const

Returns a pointer to the parent frame graph node.

If the parent of this node is not a frame graph node, this method will recursively look for a parent node that is a frame graph node.
