Using OpenGL to plot a mesh

That is exactly why i'd like as many FTN95 users as possible used OpenGL and shared their knowledge - i simply do not know a lot of things in OpenGL ! Making such menu is probably very easy task but i need an example to learn from.

BTW, did you implement saving FTN95 OpenGL screen as John suggested? I found my own code for that.

I recently ask how to plot an eps plot.

Following the link you will find some example code. Look for the subroutine triangulation_polt_eps. The subroutine is in the geompack2.f90 file.
