Struct bevy::render::view::VisibleEntities

pub struct VisibleEntities {
    pub entities: Vec<Entity>,
}

Collection of entities visible from the current view.

This component contains all entities which are visible from the currently rendered view. The collection is updated automatically by the VisibilitySystems::CheckVisibility system set, and renderers can use it to optimize rendering of a particular view, to prevent drawing items not visible from that view.

This component is intended to be attached to the same entity as the Camera and the Frustum defining the view.

Fields

entities: Vec<Entity>
