Parameter-invariant differential properties of a planar curve.

Fields

point: DVec2

Evaluated point.

unit_tangent: DVec2

Unit tangent in increasing-parameter direction.

curvature: f64

Unsigned parameter-invariant curvature.

signed_curvature: f64

Signed planar curvature; positive bends toward the tangent’s left normal.

curvature_vector: DVec2

Left unit normal scaled by signed curvature.

Trait Implementations

impl Clone for CurveDifferential2

fn clone(&self) -> CurveDifferential2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CurveDifferential2

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

Formats the value using the given formatter.

impl PartialEq for CurveDifferential2

fn eq(&self, other: &CurveDifferential2) -> 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.
