详细描述

A Qt3DRender::QTechniqueFilter specifies which techniques are used by the FrameGraph when rendering the entities. QTechniqueFilter specifies a list of Qt3DRender::QFilterKey objects and Qt3DRender::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 .
