Concept definition

template<typename T, typename SHAPE>
concept shape = requires (SHAPE const& shape, glm::tvec2<T> pt, T t)
    {

edge_length() should return the total length of this shape's edge.

        { shape.edge_length() } -> std::convertible_to<T>;
 

edge_point_alpha(t) should return a point on the shape edge at percentage t from an arbitrary start point. t should be normalized between 0 and 1 where 0 is the beginning of the shape edge, and 1 is the end.

        { shape.edge_point_alpha(t) } -> std::convertible_to<glm::tvec2<T>>;
 

edge_point(t) should return a point on the shape edge at distance t from an arbitrary start point. t should be between 0 and L where L is the edge_length()

        { shape.edge_point(t) } -> std::convertible_to<glm::tvec2<T>>;
 

bounding_box() should return an axis-aligned minimum bounding rectangle of this shape.

        { shape.bounding_box() } -> std::convertible_to<trec2<T>>;
 

closest_point_to(pt) should return the point of the shape that is closest to pt.

        { shape.closest_point_to(pt) } -> std::convertible_to<glm::tvec2<T>>;
 
        // interval<T> projected_on_axis(glm::tvec2<T> axis) const;
    }
