Using Geomview for "live 3-D manipulation" in the Visualization Lab. (Burton Hall 302)

In your Mathematica session, you must enter the following command to be able to load Graphics3D objects into Geomview.
(Make sure you type the following exactly as shown, with backquotes and no spaces):

<<Local`OOGL`

x = (2 + Cos[1.5 t]) Cos[t];
y = (2 + Cos[1.5 t]) Sin[t];
z = Sin[1.5t];
mycurve = ParametricPlot3D[ {x,y,z},{t,0,12.5}]

Now you load objects into Geomview this way:

Geomview["trefoil", mycurve]
