[vtkusers] expcos.cxx and expcos.tcl runtime differences

[Michael Norton]

hi,

I noticed on my Mac OS X install that the runtime of expcos.cxx and 
expcos.tcl differ in the way the bessel function is initially displayed.
The source in cxx looks pretty straight forward with the tcl.

The question I guess is, how do I change the camera angle from an overhead 
view of the function to one say off from the side? How do I change the 
camera angle?

thanks.
