Struct CubicBezierSpline 

pub struct CubicBezierSpline {
    pub segments: Vec<[Vec3; 4]>,
    pub closed: bool,
    /* private fields */
}

Fields

segments: Vec<[Vec3; 4]>

Control points in groups of 4: P0, P1, P2, P3 per segment Adjacent segments share endpoints: P3 of seg i == P0 of seg i+1

closed: bool
