Struct TorusSection3

pub struct TorusSection3 {
    pub torus: TorusCarrier,
    pub graph: AngleGraph2,
}

A plane’s or sphere’s section of a torus, in space: the torus point at (graph.angle(t), t).

Fields

torus: TorusCarrier

The torus the curve lies on.

graph: AngleGraph2

The curve in the torus’s parameters.

Implementations

impl TorusSection3

pub fn point(&self, t: Scalar) -> Option<Point3>

Point at t.

pub fn tangent(&self, t: Scalar) -> Option<Vec3>

Tangent at t: P_u du/dt + P_v.

pub fn bend(&self, t: Scalar) -> Option<Vec3>

Second derivative at t: P_uu u'^2 + 2 P_uv u' + P_vv + P_u u''.

Trait Implementations

impl Clone for TorusSection3

fn clone(&self) -> TorusSection3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TorusSection3

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

Formats the value using the given formatter.

impl PartialEq for TorusSection3

fn eq(&self, other: &TorusSection3) -> 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.
