The Tcl3D presentation is divided into 3 sections:
- Information
- Help and documentation
- Demos and tutorials

The information menu gives you access to different
types of information (OpenGL, Tcl3D, ...), which
are shown as animated OpenGL text.
More and detailed information are available using
the Tcl3D application OglInfo.

The demos and tutorials menu has lots of
sample programs:
4 categories are currently available:
- Library specific demos contain scripts showing
  features specific to the wrapped library.
- OpenSceneGraph specific demos.
- Tutorials and books contain scripts, which have
  been converted from C to Tcl3D, coming from the
  following sources:
    The OpenGL Red Book
    The NeHe tutorials
    Kevin Harris' CodeSampler page
    Vahid Kazemi's GameProgrammer page
    Norbert Nopper's core profile demos
- Tcl3D specific demos contain scripts not fitting
  into any other category.
