Struct bevy::render::primitives::Frustum
pub struct Frustum {
pub half_spaces: [HalfSpace; 6],
}
Expand description
A region of 3D space defined by the intersection of 6 HalfSpace
s.
Frustums are typically an apex-truncated square pyramid (a pyramid without the top) or a cuboid.
Half spaces are ordered left, right, top, bottom, near, far. The normal vectors of the half-spaces point towards the interior of the frustum.
A frustum component is used on an entity with a Camera
component to
determine which entities will be considered for rendering by this camera.
All entities with an Aabb
component that are not contained by (or crossing
the boundary of) the frustum will not be rendered, and not be used in rendering computations.
This process is called frustum culling, and entities can opt out of it using
the NoFrustumCulling
component.
The frustum component is typically added from a bundle, either the Camera2dBundle
or the Camera3dBundle
.
It is usually updated automatically by update_frusta
from the
CameraProjection
component and GlobalTransform
of the camera entity.

Implementations§
§impl Frustum
impl Frustum
pub fn from_view_projection(view_projection: &Mat4) -> Frustum
pub fn from_view_projection(view_projection: &Mat4) -> Frustum
Returns a frustum derived from view_projection
.
pub fn from_view_projection_custom_far(
view_projection: &Mat4,
view_translation: &Vec3,
view_backward: &Vec3,
far: f32
) -> Frustum
pub fn from_view_projection_custom_far( view_projection: &Mat4, view_translation: &Vec3, view_backward: &Vec3, far: f32 ) -> Frustum
Returns a frustum derived from view_projection
,
but with a custom far plane.
pub fn intersects_sphere(&self, sphere: &Sphere, intersect_far: bool) -> bool
pub fn intersects_sphere(&self, sphere: &Sphere, intersect_far: bool) -> bool
Checks if a sphere intersects the frustum.
