|The 3-D Canvas Widget provides Tk programs with 3-D graphics capabilities through the use of OpenGL. But the 3-D Canvas widget is not another thin wrapper around the OpenGL interface. This widget is a much higher-level abstraction. Just as the built-in canvas widget of Tk is a high-level abstraction of the X11 drawing routines, so too the 3-D Canvas widget is a high-level abstraction of OpenGL.
