Struct Frustum 

pub struct Frustum {
    pub planes: [Plane; 6],
}

A view frustum defined by 6 planes (near, far, left, right, top, bottom).

Fields

planes: [Plane; 6]

The six bounding planes of the frustum.

Implementations

impl Frustum

pub fn from_view_projection(vp: &Mat4) -> Self

Extract frustum planes from a combined view-projection matrix.

The resulting planes have inward-facing normals.

pub fn contains_point(&self, point: &Vec3) -> bool

Test whether a point lies inside (or on) the frustum.

pub fn intersects_sphere(&self, center: &Vec3, radius: Real) -> bool

Test whether a sphere intersects the frustum.

impl Frustum

pub fn contains_sphere(&self, center: &Vec3, radius: Real) -> bool

Test whether a sphere is fully contained inside the frustum.

Returns true if every plane’s signed distance to center is ≥ radius.

pub fn intersects_aabb(&self, aabb: &Aabb) -> bool

Test whether an axis-aligned bounding box (AABB) intersects the frustum.

Uses the separating-axis theorem: for each frustum plane, if all 8 corners of the AABB are on the outside half-space, the AABB is rejected.

pub fn extract_from_view_proj(vp: &Mat4) -> Self

Build a frustum directly from a combined view-projection matrix.

Alias for Frustum::from_view_projection with a more explicit name.

Trait Implementations

impl Clone for Frustum

fn clone(&self) -> Frustum

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Frustum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
