Qt3DRender.QRenderTargetSelector ¶

概要 ¶

详细描述 ¶

A QRenderTargetSelector is used to select active QRenderTarget for the FrameGraph. When QRenderTargetSelector is present in the FrameGraph, the rendering is directed into QTexture objects or draw buffers instead of the surface specified in the QRenderSurfaceSelector . A render buffer is automatically generated for an attachment point if drawBuffers contain attachment point that any output in the QRenderTarget do not specify. If the drawBuffers is empty, the renderer will default to using all the outputs in QRenderTarget .
