Module frustum 

Module for the drawing of Frustums.

Camera entities are spawned with a Frustum component, which describes a camera’s field of vision. With this module, a camera’s frustum can be drawn with gizmos. This is useful for debugging what a camera can see and what entities in the scene will be subject to the camera’s frustum culling, especially when combined with drawing Aabb gizmos.

There are two ways to enable gizmo drawing of a Frustum:

1. The ShowFrustumGizmo component can be added to individual camera entities.

fn setup(mut commands: Commands) {
    commands.spawn((Camera2d, ShowFrustumGizmo::default()));
}

2. Setting the FrustumGizmoConfigGroup configuration’s draw_all field to true will draw every frustum. Note that this will include drawing bevy_light SpotLight Frustums.

fn turn_on_frustum_gizmos(mut config: ResMut<GizmoConfigStore>) {
   config.config_mut::<FrustumGizmoConfigGroup>().1.draw_all = true;
}
