QLayer露
- PyQt5.Qt3DRender.QLayer
Inherits from QComponent.
Description露
The QLayer class provides a way of filtering which entities will be rendered.
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.
