[−][src]Function nannou::geom::line::join::miter::next_pair

pub fn next_pair<S>(
    half_thickness: S, 
    point_a: &mut Option<Point2<S>>, 
    point_b: &mut Option<Point2<S>>, 
    next_point: Option<Point2<S>>
) -> Option<[Point2<S>; 2]> where
    S: BaseFloat, 

Determine the next vertex pair in the miter sequence given the two previous points and the next if one exists.

  • half_thickness: half the thickness of the line.
  • point_a: the point in the sequence prior to the last point.
  • point_b: the last point in the sequence.
  • next_point: the next point in the sequence.

This function expects that point_a is None and point_b is Some (containing the first point in the sequence) when beginning the sequence.

This function is used within both the VertexPairs iterator and the polyline().vertices() draw builder method.
