Hi, it sounds like PDL's PDL::Graphics::TriD module will display it. It also does a Polar coordinate system. You might want to ask on the PDL maillist. You will find some real experts there who can assist in setting up your piddles. The secret is in understanding the piddles. :-)

In the meantime, here are a couple of simple TriD examples. More examples, including how to do animation is at TriD_Tutorial

A polar coordinate system example:

#!/usr/bin/perl
use warnings;
use PDL;
use PDL::Graphics::TriD;

# POLAR2D A 2-D polar coordinate system. [$piddle] is interpreted as t
+he z coordi
#               nate over theta and r (theta = the first dimension of 
+the piddle).

$size = 25;

$x = ( xvals zeroes $size+ 1, $size + 1 );# / $size;

print "$x\n";
print join ' ',dims $x;
print "\n";


$y = ( yvals zeroes $size+ 1, $size + 1 );# / $size;
#$z = 0.5 + 0.5 * ( sin( $x * 6.3 ) * sin( $y * 6.3 ) )**3;    # Bumps

$z= $x * 10;

$r = $x;
$g = $y;
$b = $z;

# The reason for the [] around $x,$y,$z:
# 1. You can give all the coordinates and colors in one piddle.
$c = ( zeroes 3, $size + 1 ) / $size;
$coords = sin( ( 3 + 3 * xvals $c) * yvals $c);
$colors = $coords;

print "hit q to continue\n";

# 2. You can use defaults inside the brackets:
lattice3d [ $z ], [ $r ];  # Note: no $x, $y, and $r is greyscale

print "hit q to continue\n";

# 3. You can plot in certain other systems as defaults
imag3d_ns [ POLAR2D, $z ], [ $r, $g, $b ];    # Draw the familiar
# bumpy surface in polar
# coordinates

A conventional 3d cartesian example using easy-to-see spheres

#!/usr/bin/perl
use warnings;
use strict;
use PDL;
use PDL::Graphics::TriD;

keeptwiddling3d();

my $piddle = pdl( [ [1,1,1],[2,2,2],[3,3,3],[4,4,4],[5,5,5],[6,6,6],[7
+,7,7],[8,8,8], [1,0,1] ] );
