Detailed Description#

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

__init__([parent=None])#

Parameters:: parent – QNode

The constructor creates an instance with the specified parent.

parentFrameGraphNode()#

Return type:: 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.
