How to use plex-viewer

[tmelorc]

I'm starting to learn javaplex and I found here a link to plex-viewer here.

I tried some example with

./run_x86.sh -complex rips_simplices.txt -points rips_points.txt

from the README file. But I got the errors below.

Do you have some idea how to fix or maybe some other software to
create simplicial complexes from data created by javaplex?

Regards and thanks in advance.

Ping @henryadams , @OgDet -- I'm not really familiar with plex_viewer myself.

I've never used plex_viewer either, but as you say maybe @OgDet has comments.

Best, Henry

I got the two README examples of plex-viewer to work by adding the javaplex jar file to CPATH in the .sh scripts.

e.g. copy javaplex-4.2.5.jar to 'examples', and change CPATH in the .sh scripts to:
CPATH="plex-viewer.jar:../lib/ext/gluegen-rt.jar:../lib/ext/jogl.jar:javaplex-4.2.5.jar"

I downloaded the files (which include the opengl lib files) from: https://github.com/ogdet/plex-viewer
