Qt3DRender.QFrameGraphNode ¶

概要 ¶

详细描述 ¶

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

class PySide2.Qt3DRender.Qt3DRender. QFrameGraphNode ( [ parent=None ] ) ¶

param parent

QNode

The constructor creates an instance with the specified parent .

PySide2.Qt3DRender.Qt3DRender.QFrameGraphNode. parentFrameGraphNode ( ) ¶

返回类型

QFrameGraphNode

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.
