I'm about to write some macros, for making some statistics with
povray ...
Creating diagrams with lines and bars semm quite easy, also for
2D-Diagrams showing surfaces ...

But how can I create a pie-chart ???
I don't want do do it with simple texturing on a cylinder, using
a radial gradient, but I want to have all segments of my pie as
own segments, to move them (later).

But how can I create all the pie-pieces ???
I thougt about an Isosurface, but that's quite slow and not
POV3.1 compatible...
Than I thought, using a CSG-operation of a cylinder and a
well-scaled/rotated cube, but this would be quite complicated to
compute, and will only work if the piece has a bit more than 0
degrees and a bit less than 180 degrees ...

Currently I think the isosurf would be the easier alternative,
but there must be another way of doing this ...

Can't I limit a cylinder to some degrees to use ???
