We managed (2 years ago, so no details anymore) to do this using normal
PrintServices for VMS software of Dec. Part of it is a PostScript to
bitmap converter. It was slow, but it worked OK.

(repost -- looks like my first try went into the bit bucket)

I'm looking for a reference on modeling with natural splines in
3 dimensions.  I saw a reasonably new book recently that was
nothing but modeling techniques for curves and surfaces in 2
and 3 dimensions--splines, Bezier curves, NURBS, etc.  Unfortunately
I don't remember what it was called.  :-(

My immediate problem:

I'm modeling paths in 3 dimensions and need some help.  Alas.
An interpolating function is required, so Bezier curves, etc.,
are out. Could someone summarize the procedure for finding and
using a parametric, natural 3-d spline?  How do the computations
differ from those used to find an interpolating function for
a table of values?  I understand that there is also a similar
interpolating method that offers local control.

(Of course, source code will always be welcome.)

I'd like to model conic paths as well.  Are there reasonably
simple interpolating functions that do a better job of modeling 
circles, ellipses, etc., than polynomial splines?  I.e., if
I just pick a fairly small number of points on a circular path,
the interpolated path will be a pretty good approximation.

       I have a question which I hope is not too basic, are there colours
which can be represented in the true HSV cone which cannot be represented
in the standard RGB cube? The text which I am reading tells me that the
HSV cone is approximated to a hexagonal cone, is this just to make HSV
and RGB strictly eqivalent?
	To my mind the HSV model is far easier to navigate within, but
if the hardware or OS approximate your colour choice to a value within
the HSVhexcone/RGB model when you choose a colour on the edge of the
HSVtruecone your work will not be as you desired.

	It is my hope that these questions are pertinent and sensible.

Use the Unix System V command `cut'
For example,

Adding a "set size .5,.5" makes everything fit on the page, but the

Yet another reason to consider removing integer arithmetic from gnuplot
in the future.  This has been discussed at various times in the past.
A few people have "undone" integer arithmetic for various reasons and
lived to tell about it.  The most common reason, and possibly the most
compelling argument, is that print 5/2 does not lie on the plot of x/2
in gnuplot.  This is very confusing to people and makes gnuplot's
calculator a difficult instrument for non-programmers.   (Of course
print 5./2 does lie on the plot of x/2, but this is not intuitive for
most people.)  I'm not aware of any other calculator or plotting package
that insists on preserving integer arithmetic.  Floor and cieling functions
are already in gnuplot, so floating truncations (which are important)
can be done without using integer arithmetic.

Why don't you use: plot 'file' using 1:3

This plots column 3 of file agains column 1 of file.

It uses native text printing for characters, and portable

	8 or 16 colours
	to run length encode or not
	plain paper or transparency printing.

Future options may include 2|4 up, and downloadable pallettes.
as urgency compels me to do the work.

I'll send this to folks on request. Do the developers of 3.3 want

Is there some documentation for the use of color in gnuplot 3.2? I'm trying
to plot multiple curves on a single set of axes. I finally figured out that
turning off the symbols on the lines causes the different curves to be plotted
in different colors, but at least one of the colors that gnuplot cycles through
(yellow, to be specific) is unreadable on my color plotter.

Here's what I'm doing:

Is there a way to specify a particular color for each curve? I've searched
through all the documentation I have (looking for the word 'color') and
haven't found any help.

Each color is considered a 'linestyle', so that you can control
the color used in the same way you would control the type of line
used with a monochrome device:

plot 'file1.dat' with lines 2, 'file2.dat' with lines 3

The integer after the keyword 'lines' is the linestyle; if not
specified, they are applied in sequence (12345...)

You might consider using the specially adapted GNUPlot sources for
Linux, which include also a special Linux-VGA driver. No need of
course if you always use X11, but some people might be interested.
Complete adaption can be found e.g. on tsx-11.mit.edu (mirrored in
