Detailed Description#

A QTechniqueFilter specifies which techniques are used by the FrameGraph when rendering the entities. QTechniqueFilter specifies a list of QFilterKey objects and QParameter objects. When QTechniqueFilter is present in the FrameGraph, only the techiques matching the keys in the list are used for rendering. The parameters in the list can be used to set values for shader parameters. The parameters in QTechniqueFilter override parameters in QMaterial , QEffect , QTechnique and QRenderPass , but are overridden by parameters in QRenderPassFilter .

class PySide6.Qt3DRender.Qt3DRender.QTechniqueFilter([parent=None])#

Parameters:: parent – PySide6.Qt3DCore.Qt3DCore.QNode

The constructor creates an instance with the specified parent.

PySide6.Qt3DRender.Qt3DRender.QTechniqueFilter.addMatch(filterKey)#

Parameters:: filterKey – PySide6.Qt3DRender.Qt3DRender.QFilterKey

Add the filterKey to the match vector.

PySide6.Qt3DRender.Qt3DRender.QTechniqueFilter.addParameter(p)#

Parameters:: p – PySide6.Qt3DRender.Qt3DRender.QParameter

Add parameter to the vector of parameters that will be passed to the graphics pipeline.

PySide6.Qt3DRender.Qt3DRender.QTechniqueFilter.matchAll()#

Return type:: .list of Qt3DRender.QFilterKey

Returns a vector of the current keys for the filter.

PySide6.Qt3DRender.Qt3DRender.QTechniqueFilter.parameters()#

Return type:: .list of Qt3DRender.QParameter
