or demo5, i
Run examples of use of pl3d.i, plwf.i, and slice3.i. With
argument I = 1, 2, or 3, run that particular demonstration.
Read the source code to understand the details of how the
various effects are obtained.
demo5,1 demonstrates the various effects which can be obtained
with the plwf (plot wire frame) function.
demo5,2 demonstrates shading effects controlled by the light3
demo5,3 demonstrates the slice3, slice2, and pl3tree functions,
as well as changing the orientation of the 3D object
interpreted function, defined at i/demo5.i line 18
