Hi Luis, Sorry to hear of those problems. Could you try the latest GitHub master version of P:G:TriD, which is somewhat updated, and see if that behaves? If you're using the system Perl, I'd recommend instead using perlbrew, since interfering with the system Perl other than through the package manager is quite dangerous.

Installation of TriD failed initially, but succeded after I installed libglfw3-dev. My system is debian/testing with xfce. Although the installation succeded, when I run the demo, > pdl pdl> demo 3d 24 new graphics windows open, black and unresponsive; the demo runs to completion but nothing. There are plenty error messages, starting with ---- Output: GLFW error 65550: Failed to detect any supported platform at /home/mochan/perl5/perlbrew/perls/perl-5.42.2/lib/site_perl/5.42.2/x86_64-linux/PDL/Graphics/TriD/GL/GLFW.pm line 43. ---- ---- OOPS!!!
