Enumeration Type Documentation

enum LeapUtilGL::eAxis

all drawing utilities draw unit sized objects centered at the origin with no rotation in the current GL drawing context (orientation, scaling, lighting configuration, etc). use glTranslatef() to change position, glScalef() to change size. these object draw without any side effects to the GL state.
