Probably this will seem a stupid question...
I wonder if there is a way to do the following:
create a simple 3D graphics made of
lines and points, maybe rotate it to
choose a good point of view, then:
generate the 2D directives that will produce
a 2D graphic that mimic the given 3D graphic,
or even better, obtain, for each line or point
in 3D the corresponding "visual" coordinates
in 2D.
I don't know if I have been clear enough.
I explain what I'm doing.
For what I need currently,
I use Mathematica not to produce the final images, but to obtain
in a fast and nice way the set of coordinates for my figures.
For example, if I want to draw a Graph, say
GraphPlot[Table[k -> Mod[Prime[k], k], {k, 20}]]
I exploit the very nice GraphPlot, then the
capability of editing in a visual way the graph,
and then when I'm satisfied with the obtained layout,
by using some simple custom functions,
I convert the graph in simple primitives for
the very good pgf Latex package.
This machinery may seem complicated (since Mathematica
can indeed produce wonderful pictures) but I
like to be able to modify my simple b&w drawings later,
on a machine where Mathematica is not available,
for example to fine-tuning the line width depending on the
printer, or the apparence of the nodes of the graph and so on...
Now I wonder if I can do something similar
in 3D. For example: issue to Mathematica some
Line[] or Cuboid[] commands to draw a cube in 3D and then
obtain back in some way the 2D lines that when
plotted in 2D will create the same scene. All I probably
need is wireframe, but some hidden edge removal will
be nice...
I apologize for the verbosity,
thanks
giovanni.
