pub fn follow<C: Condition + ?Sized>(
condition: &C,
start: &[f64],
options: Marching,
tol: Tolerances,
) -> OgeomResult<Walked>Expand description
Follow a condition’s curve both ways from a starting point.
Forwards first; if that closes, the curve is a loop and there is nothing behind. Otherwise the backward half is walked and the two are joined.
§Errors
OgeomError::Construction if the
settings are unusable, or the start does not have the condition’s own
number of unknowns.
