详细描述

A Qt3DRender::QRenderPassFilter FrameGraph node is used to select which Qt3DRender::QRenderPass objects are selected for drawing. QRenderPassFilter specifies a list of Qt3DRender::QFilterKey objects and Qt3DRender::QParameter objects. When QRenderPassFilter is present in the FrameGraph, only the QRenderPass objects, whose Qt3DRender::QFilterKey objects match the keys in QRenderPassFilter are selected for rendering. If no QRenderPassFilter is present, then all QRenderPass objects are selected for rendering. The parameters in the list can be used to set values for shader parameters. The parameters in QRenderPassFilter override parameters in QTechniqueFilter , QMaterial , QEffect , QTechnique and QRenderPass .
