Detailed Description¶

A QLayerFilter can be used to instruct the renderer as to which layer(s) to draw in that branch of the frame graph. QLayerFilter selects which entities to draw based on the QLayer instance(s) added to the QLayerFilter and as components to QEntity .

QLayerFilter can be configured to select or discard entities with a specific QLayer depending on the filterMode property. By default, entities referencing one of the QLayer objects that are also being referenced by the QLayerFilter are selected ( AcceptAnyMatchingLayers ).

Within the FrameGraph tree, multiple QLayerFilter nodes can be nested within a branch going from root to a leaf. In that case the filtering will first operate on all entities of the scene using the filtering method specified by the first declared QLayerFilter . Then the filtered subset of entities will be filtered again based on the filtering method set on the second QLayerFilter declared. This is then repeated until all QLayerFilter nodes of the branch have been consumed.

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

param parent:

PySide2.Qt3DCore.Qt3DCore.QNode

The constructor creates an instance with the specified parent .
