pub fn reach_past(
hull: &[Vector3],
plane: &CoordinateSystem,
sign: f64,
) -> GeopResult<f64>Expand description
How far along plane’s normal — forwards for sign = 1, backwards for
-1 — reaches past everything of the solid whose convex hull hull
spans: a side going up to its next face has to be built at least that
long to meet whichever face that is.
