Function parry3d::query::details::clip_halfspace_polygon

pub fn clip_halfspace_polygon(
    center: &Point<Real>, 
    normal: &Vector<Real>, 
    polygon: &[Point<Real>], 
    result: &mut Vec<Point<Real>>
)

Cuts a polygon with the given half-space.

Given the half-space center and outward normal, this computes the intersecting between the half-space and the polygon. (Note that a point pt is considered as inside of the half-space if normal.dot(&(pt - center)) <= 0.0.
