thank you Rob very much for uploading opengl 0.63 , now the examples run more smoothly, and i get rid of from strange hang out sometimes when running the examples using the beautiful 3D PDL::Graphics::TriD module here is an animated mandelbrot i copied from TriDGallery.PM in "C:\Perl\site\lib\PDL\Demos"
it is displaying an animated color mandel set like this :

indeed i have astonished by the versatile and deep features this PDL module has especially with its 2D and 3D features.
use PDL; use PDL::Graphics::TriD;
#Color Mandelbrot animation
nokeeptwiddling3d();
$a=zeroes 300,300;$r=$a->xlinvals(-1.5,0.5);
$i=$a->ylinvals(-1,1);
$t=$r;$u=$i;
for(1..30){$q=$r**2-$i**2+$t;
$h = 2*$r*$i+$u; $d=$r**2+$i**2;
$a=lclip($a,$_*($d>2.0)*($a==0));
($r,$i) = map{$_->clip(-5,5)}$q,$h;
imagrgb[($a==0)*($r/2+0.75),($a==0)*($i+1)/2,$a/30]};
# [press 'q' in the graphics window when done]
keeptwiddling3d();
twiddle3d();

regarding the error "Interface HASH(0X25C224) is not known!" i still get it even if i add
use PDL;
use PDL::Graphics2D;
use PDL::Graphics::PGPLOT::Window;
use PDL::Graphics::PGPLOT;
it gives the error at the line

my $w = PDL::Graphics2D->new($winopt);

if i use "PDL::Graphics::PGPLOT::Window" instead as the code below i get an error "Undefined subroutine &main::imag2d called at err.pl line 13"
use PDL;
use PDL::Graphics2D; #imports imag2d() and twiddle()
use PDL::Graphics::PGPLOT::Window;
use PDL::Graphics::PGPLOT; 

my $winopt = {Device => "/GW", WindowWidth => 7, Aspect => 1}; 
#my $w = PDL::Graphics2D->new($winopt);
my $w = PDL::Graphics::PGPLOT::Window->new($winopt);
$a = sequence(64,48,3);  # make test RGB image
  $a = $a->mv(2,0);        # color must be dim(0) with size [0..4]
  $a /= $a->max;           # pixel values in [0.0,1.0]
  $a = sin(10*$a);
  $w = imag2d($a);

it can be an ms windows specific problem, sure the developer get it working since the example is here :
http://kobesearch.cpan.org/htdocs/PDL/PDL/Graphics2D.html
so i will post to the pdl forum

thank you Rob for all your efforts.
