Detailed Description
Encapsulates a Technique.
A Qt3DRender::QTechnique specifies a set of Qt3DRender::QRenderPass objects, Qt3DRender::QFilterKey objects, Qt3DRender::QParameter objects and a Qt3DRender::QGraphicsApiFilter, which together define a rendering technique the given graphics API can render. The filter keys are used by Qt3DRender::QTechniqueFilter to select specific techinques at specific parts of the FrameGraph. If the same parameter is specified both in QTechnique and QRenderPass, the one in QTechnique overrides the one used in the QRenderPass.
See also Qt3DRender::QEffect.
