Struct CapsuleFrustum 

pub struct CapsuleFrustum {
    pub r_bottom: f64,
    pub r_top: f64,
    pub height: f64,
}

A capsule-like shape with different radii at each end (a “swept frustum”).

The axis runs along Y from y=0 (radius r_bottom) to y=height (radius r_top). The radius varies linearly along the axis.

Fields

r_bottom: f64

Radius at the bottom cap (y=0).

r_top: f64

Radius at the top cap (y=height).

height: f64

Total height (length of axis segment).

Implementations

impl CapsuleFrustum

pub fn new(r_bottom: f64, r_top: f64, height: f64) -> Self

Create a new capsule frustum.

pub fn radius_at_height(&self, y: f64) -> f64

Interpolated radius at height y (clamped to [0, height]).

pub fn volume(&self) -> f64

Approximate volume (frustum cone + two hemispheres of different sizes).

pub fn contains_point(&self, p: [f64; 3]) -> bool

Returns true if point p is inside the frustum.

pub fn sdf(&self, p: [f64; 3]) -> f64

Signed distance to the frustum surface (approximate).

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for CapsuleFrustum

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