Struct CurveDifferential3

pub struct CurveDifferential3 {
    pub point: Point3,
    pub unit_tangent: Vec3,
    pub curvature: Scalar,
    pub curvature_vector: Vec3,
}

Parameter-invariant differential properties of a spatial curve.

Fields

point: Point3

Evaluated point.

unit_tangent: Vec3

Unit tangent in increasing-parameter direction.

curvature: Scalar

Unsigned parameter-invariant curvature.

curvature_vector: Vec3

Normal-acceleration direction scaled by curvature.

Trait Implementations

impl Clone for CurveDifferential3

fn clone(&self) -> CurveDifferential3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CurveDifferential3

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

Formats the value using the given formatter.

impl PartialEq for CurveDifferential3

fn eq(&self, other: &CurveDifferential3) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
