| |
| A QFrustumCulling class enables frustum culling of the drawable entities based on |
| the camera view and QGeometry bounds of the entities. If QFrustumCulling is present in |
| the FrameGraph, only the entities whose QGeometry bounds intersect with the camera |
| frustum, i.e. the view of the camera, are drawn. If QFrustumCulling is not present, |
| all drawable entities will be drawn. The camera is selected by a QCameraSelector |
| frame graph node in the current hierarchy. Frustum culling can save a lot of GPU |
| processing time when the rendered scene is complex. |
