class  kjb::qd::PolyPath
 represents an open polygonal path with a tangent at each point More...


 Classes and functions for dealing with trajectory files.
 support for the path algorithm I call the quasi-Dijkstra method.


Vector2 kjb::qd::get_unit_vector_2x_angle (const Vector2 &v)
 double the angle relative to (1,0) and return a unit vector that way. More...
Vector2 kjb::qd::get_unit_vector_2x_angle_nothrow (const Vector2 &v)
 like get_unit_vector_2x_angle() but return zero vector on zero input More...
Vector2 kjb::qd::get_unit_vector_2x_angle_of_unit_vector (const Vector2 &)
 like compute_unit_vector_2x_angle but for unit-magnitude input. More...
bool kjb::qd::is_valid_as_polypath (const PixPath &, bool throw_failure=false)
 test whether a pixel path is convertible to PolyPath (maybe say why) More...
