Struct qt_3d_render::QFrustumCulling

#[repr(C)]pub struct QFrustumCulling { /* fields omitted */ }

Enable frustum culling for the FrameGraph

C++ class: Qt3DRender::QFrustumCulling.

C++ documentation:

Enable frustum culling for the FrameGraph

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.

Methods

impl QFrustumCulling

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

Calls C++ function: virtual const QMetaObject* Qt3DRender::QFrustumCulling::metaObject() const.
