Struct CapsuleFrustum 

Source 
pub struct CapsuleFrustum {
    pub r_bottom: f64,
    pub r_top: f64,
    pub height: f64,
}
Expand description

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§

Source§

impl CapsuleFrustum
