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.
