If you are a C++ programmer you could write a simple interpreter for your
text file which translates ball & stick directives into ssgShapes calls.
E.g. when the interpreter finds a ball directive it should create a
ssgaSphere and add it to the scene graph, and ssgaCylinder for sticks
instead (less than 20-lines code I think).

Unfortunately none of the 3D format loaders of the Plib/SSG support
high-level (sphere, cylinder, etc.) primitive generation.

Plib offers a sample demo viewer in source code you could customize for your
app.
