drawing primatives with GNU Octave...

[James Moliere]

Hello,
I'd like to draw 3D primitives with Octave such as cubes, cylinders,
spheres, etc.  I don't want to enter equations for these, I'd prefer to
use something like openGL commands such as 

drawCylinder(x, y, z, radius, length, slices);

If this exists, please show me.  I don't want to use equations to draw
these primitives.  If not, can anyone direct me on how to integrate a 3D
library like OpenSceneGraph into Octave?  I would prefer something like
a guide instead of source code.

Thanks!
