Old FORTRAN programs, libraries, graphics

[emanuel stiebler]

Being stuck at home, was musing the idea to look into some graphics
software from the '70's, or early 80's ...

Looking for some wire frames, hidden line removal, 3d graphics...

Any pointers?

View month ago or longer, somebody on this list recovered some large
package of FORTRAN code, and wanted to invest it, but I think it was
posted under a wrong subject, so I can't find it anymore ...

THANKS!
