Struct DeformableCapsule 

Source 
pub struct DeformableCapsule {
    pub a: [f64; 3],
    pub b: [f64; 3],
    pub radius: f64,
}
Expand description

Unlike the axis-aligned Capsule, this capsule can have its two hemispherical cap centres at any positions in 3D space.

Fields§

§a: [f64; 3]

First endpoint of the medial axis.

§b: [f64; 3]

Second endpoint of the medial axis.

§radius: f64

Capsule radius.
