Calculate, and work with, the winding order

Required Methods

fn winding_order(&self) -> Option<WindingOrder>

Return the winding order of this object

fn points_cw<'a>(&'a self) -> Box<Iterator<Item = &'a Point<T>> + 'a>

Iterate over the points in a clockwise order

The object isn't changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear clockwise

fn points_ccw<'a>(&'a self) -> Box<Iterator<Item = &'a Point<T>> + 'a>

Iterate over the points in a counter-clockwise order

The object isn't changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear counter-clockwise

fn make_cw_winding(&mut self)

Change this objects's points so they are in clockwise winding order

fn make_ccw_winding(&mut self)

Change this line's points so they are in counterclockwise winding order

Provided Methods

fn is_cw(&self) -> bool

True iff this clockwise

fn is_ccw(&self) -> bool

True iff this is wound counterclockwise

fn clone_to_winding_order(&self, winding_order: WindingOrder) -> Self where
    Self: Sized + Clone, 

Return a clone of this object, but in the specified winding order

fn make_winding_order(&mut self, winding_order: WindingOrder)

Change the winding order so that it is in this winding order
