Module arrow
OpenGL arrows.
The arrow module allows creation and drawing of arrows. Clients draw
using graphics3d.common.Group instances, aliased here as ArrowGroup, not
through Arrow instances.
Drawing is done in whatever is the current GL rendering context and
current GL window. So you must set those prior to drawing. If you are
using this with Maestro's drawing callback mechanism you need not worry
about the above details. These are handled for you automatically.
Control over the endpoints, radius, color, resolution and transparency
of a arrow are provided. See the Arrow class for more info.
To draw any number of arrows create Arrow instances, add them to a
Group instance, then invoke the Group's draw() method.
