I have here the version 3.2 of theGNUPLOT program and use it on an MSDOS
computer. I think that the calculation of the complex gamma function is
not too difficult and can easily be included in GNUPLOT. Here is a routine
to compute the gamma-function for complex arguments which is suitable for
inclusion in GNUPLOT.


/* This approximation is based on Stirlings formula, see e.g.
 M. Abramowitz, I.A. Stegun, Handbook of mathematical functions */

f_gamma()
 {
 struct value a;
 static double sti[]={1./12,-1./360,1./1260,-1./1680,5/(66.*90),
		      -691/(132.*2730),7/(6.*182)};
 double xr,xi,gr,gi,z1,z2,z3,z4,z5,z6,z7;
 int    n,i;
 char spiegel;
  (void)pop(&a);xr=real(&a);xi=imag(&a);
  spiegel=1;n=0;
  if(xr<0) xr=1-xr; else spiegel=0;
  z1=196-14*xi;
  if((xr-1)*(xr-1)<z1) n=(int)(sqrt(z1)-xr)+2;
  xr+=n;
  if(xr<1) {n=1;xr++;}
  z3=xr*xr+xi*xi;z4=0.5*log(z3);z5=atan(xi/xr);
  gr=(xr-0.5)*z4-xi*z5-xr+0.5*log(2*Pi);
  gi=(xr-0.5)*z5+xi*z4-xi;
  z4=-xi/z3;z3=xr/z3;
  z1=z3*z3-z4*z4;z2=2*z3*z4;
  z5=sti[6];z6=0;
  for(i=5;i>=0;i--)
   {z7=z5*z1-z6*z2;z6=z5*z2+z6*z1;z5=z7+sti[i];}
  gr += z5*z3 - z6*z4;gi+=z5*z4+z6*z3;
  if (gr>88){undefined = TRUE;z5=gr;} else z5=exp(gr);
  gr=z5*cos(gi);gi=z5*sin(gi);
  if(n>0)
   { z1=xr-1;z2=xi;
     for(i=2;i<=n;i++)
      {z3=z1*(xr-i)-z2*xi;z2=z1*xi+z2*(xr-i);z1=z3;}
     z3=z1*z1+z2*z2;z4=(gr*z1+gi*z2)/z3;
     gi=(gi*z1-gr*z2)/z3;gr=z4;
   }
   if(spiegel)
    {z3=exp(-Pi*xi);
     z1=0.5*sin(Pi*(xr-n))*(z3+1/z3);z2=-0.5*cos(Pi*(xr-n))*(z3-1/z3);
     z3=z1*gr-z2*gi;z2=z1*gi+z2*gr;z1=z3;
     if(z3==0.0){undefined = TRUE; z3=1.;} else z3=z1*z1+z2*z2;
     gr=Pi*z1/z3;gi=Pi*z2/z3;
    }
  push( complex(&a,gr,gi));
 }

To include this routine in the GNUPLOT program, I have modified the files
"STANDARD.C" and "PLOT.H". In "STANDARD.C" I have removed all the stuff
about the  gamma-function and replaced it by the above function. Then I have
defined GAMMA in "PLOT.H" by:

#define GAMMA gamma

Then it works fine after compilation with Turbo C.

Hi Everyone .. ( Not to sure if I have sent this to the right place,
                 in fact I don't think there is a right place for this)

As you may have read already I am trying to gather some information 
regarding the writing of a GUI for the well Known & used raytracers
such as POV, Rayshade & Radiance.

What I want to do is implement my own standard script language that I
can easily generate using the GUI. Once generated I want to convert the
script into the script language of the target raytracer ie POV. I 
initially want to do this for only one raytracer ie POV, but in the end
I need a way of selecting which raytracer script format to generate.

Not having done anything like language definition and parsing before I
was hoping that someone out there could point me in the right direction.

(1)

Is there already any source code out there to convert from one raytracer's
script to another that I could look at. Just to give me an idea as to how to
do this.

(2)

Should I write a BNF Formal language specification and then use a technique
such as recursive decent to evaluate the source script and then generate
the destination script.

(3)

Anyone elses thoughts and Ideas on this would be very helpfull. There are
probably lots of ways of doing this, its just a case of finding the best
one.

Thank You For any help & for sparing the time to write back.

Sorry, you are perfectly right!  Here's a (hopefully) useful description of
my program:

o What can you do with graphtal:

- generate geometric objects like trees, plants, skyscrapers, ...
- you can produce different kinds of output, which include 
  output for rayshade, X11 or ppm (portable pixmap).
- you can use the models produced by graphtal into your own images.
- you may produce animations with graphtal (see the examples).
- some example L-system descriptions are included 
  (birchtree, firtree, a plant, ...), you can use to start with.
- ...
   

o How does an L-system work:

I don't want to explain what L-systems are all about. Here's just
the principle:

An L-system description is a collection of rules. graphtal takes
these rules and applies them to a string of commands. This string
is transformed into another string due to these rules.
The commands in the string control a 3D turtle and you get the path
of the turtle as output.

Hi, I've checked the FAQ and can't find this one, even though its quite basic.

I'm developing a dynamic graphic simulation, and I need advice on the subject.
I have many circles, all the same radius, flowing down a channel
(in the future they will be spheres in a tube.)

I need the quickest algorithm for calculating the distance between a
point (x,y) and a line f(x).  I will have an initial distance which will be updated at
each major time slice.

The straightforward way is iteratively better guesses until the perpendicular
is found which passes through (x,y).  Is there a quicker way?  I need to check
many of these and want the quickest algorithm.

Does anyone have a reference?

Or, if you don't mind being unorthodox and shunned at parties, use
the Independent JPEG Group's software as a quantizer.  It reads targa
directly.  On MS-DOS, I think you give it input and output files, so
you'd do:

PC> cjpeg -Q 100 image.tga image.jpg
PC> djpeg -G image.jpg image.gif

This is the best quantizer I know of.

Thats because Machine.FLI is a 640x480 FLI, and the non 320x200 FLI format
is slightly different.

However, as always, there is help!

I have re-hacked Xflick to support other-than 320x200 FLI'cs, AS WELL AS
using the public colormap (i.e. no need to click the damned window any more,
or you can run multiple anims on screen!). The only thing is, hey, I have
completely forgotten to upload it anywhere!

I will rectify this sad mistake real-soon-now and post here when I have.

   Well, for the PC/DOS platform 3D Studio is about as good as you get.  I 
would reccomend using it in collaboration with POV though.  The internal 
rendering engine is fine for what it does; rendering, if you are looking at 
doing serious ray-tracing POV is a good choice.

In Simtel's <MSDOS.GRAPHICS> (also on garbo.uwasa.fi) you'll find PVQUAN15.ZIP.

I don't know what 3DS is or does, but I've put together a set of utilities
