| |
| \brief When a Qt3DRender::QNoPicking node is present in a FrameGraph |
| branch, this prevents the render aspect from performing picking selection |
| for the given branch. |
| |
| When disabled, a Qt3DRender::QNoPicking node won't prevent picking from |
| being performed. Toggling the enabled property is therefore a way to make a |
| Qt3DRender::QNoPicking active or inactive. |
| |
| When using multiple subviewports in the FrameGraph, QNoPicking can be |
| useful to prevent picking conflicts between overlapping viewports or non |
| visual ones. It can also be used as an optimization to prevent unnecessary |
| work for hidden viewports or for sections of the scenes which don't require |
| any picking. |
