Required Methods§

Source

fn wireframe_points<E>(&self, output: &mut E)
where E: Extend<LineVertex>,

Represent this object as a line drawing, or wireframe.

The generated points should be in pairs, each pair defining a line segment. If there are an odd number of vertices, the caller should ignore the last.

Design note: This method accepts a destination to write to, rather than returning an iterator, because if it did return an iterator, it would be difficult to compose in ways like allocating a temporary Wireframe and delegating to that, if it borrowed its input, and would risk composing a very large yet unnecessary iterator struct if it owned its input. This way, composition is simply calling further functions.
