详细说明

禁用时，Qt3DRender::QNoPicking 节点不会阻止执行采摘。因此，切换启用属性是使Qt3DRender::QNoPicking 处于活动或非活动状态的一种方法。

在 FrameGraph 中使用多个子视口时，QNoPicking 可用于防止重叠视口或非可视视口之间的拾取冲突。它还可以用作一种优化，以防止隐藏视口或场景中不需要任何拾取的部分出现不必要的工作。

Qt3DRender::QViewport *viewport = new Qt3DRender::QViewport();
Qt3DRender::QCameraSelector *cameraSelector = new Qt3DRender::QCameraSelector(viewport);
Qt3DRender::QNoPicking *noPicking = new Qt3DRender::QNoPicking(cameraSelector);

Qt3DRender::QClearBuffers *clearBuffers = new Qt3DRender::QClearBuffers(noPicking);
clearBuffers->setBuffers(Qt3DRender::QClearBuffers::ColorDepthBuffer);

Qt3DRender::QRenderPassFilter *mainPass = new Qt3DRender::QRenderPassFilter(cameraSelector);
....
Qt3DRender::QRenderPassFilter *previewPass = new Qt3DRender::QRenderPassFilter(cameraSelector);
