A camera frustum for view culling.

Used to discard objects outside the camera view before rendering. Defined by six half-space planes: left, right, top, bottom, near, far.

Implementations

impl Frustum

pub fn from_matrix(vp: Mat4) -> Self

Build a frustum from a view-projection matrix.

Works with row-major matrices (as provided by glam::Mat4).

pub fn sphere_inside(&self, center: Vec3, radius: f32) -> bool

Test if a sphere overlaps the frustum.

pub fn aabb_inside(&self, bounds: &Aabb) -> bool

Test if an AABB overlaps the frustum (conservative test).

pub fn point_inside(&self, p: Vec3) -> bool

Test if a point is inside the frustum.
