I'm looking for a way of creating a picture of a function f(x) that rotates
around the x-axis, like the pictures you find in the calculus textbooks.
Any ideas on how to do this with epix?
Hi Gunnar,
I just replied to your post at c.t.t with a few links to samples. Some
of the source files are attached to this message. :)
If you want simple line figures or shaded surfaces without too many
on-surface markings, that's no problem. In general, the process isn't
quite as painless as it should be. The idea is to divide the scene into
visual layers (the back half of the surface, the longitudinal plane
containing coordinate axes and the profile curve, the front half of the
surface, any overall labels, etc.) and to layer these pieces manually in
the input file.
Please ask if you have trouble getting the effect(s) you want.
Best,
Andy
