pub fn seed_feet(
a: &Geometry,
pa: Option<&Pose>,
b: &Geometry,
pb: Option<&Pose>,
) -> GeopResult<Vec<Scalar>>Expand description
Where on a the foot point of the follower b is, where pa and pb
put them: of a curve its t, of a surface its u and v, nearest the
follower’s point. A seed for a solve, which finds the true one: a free
choice.
