IRIT - Modeling Enviroment
« on: January 19, 2026, 03:54:32 pm »
Hello

This is a little subject I want to share with you. It is not important as far as I can tell, but I want to let it documented just in case.

"IRIT is a freeform geometric modeling environment that allows one to model general freeform surfaces' based models as well as polygonal objects, and use Boolean operations on both."

The IRIT modeling package is free for noncommercial use and it is copyrighted to Gershon Elber. It is not open source under one of the common licenses.

Long time ago (1997), someone ported IRIT 7 and shared the binaries with the source code. I have the source code that contains an OS/2 makefile here: https://github.com/OS2World/APP-GRAPHICS-IRIT

The modern source code is still available (free for noncommercial use) here: https://gershon.cs.technion.ac.il/irit/irit-sm.zip

I got a request to delete the source code since it is old. (Current version is 13)
-- https://github.com/OS2World/APP-GRAPHICS-IRIT/issues/1

I have to comply to that, since it is not traditional open source software. I will turn the repository private. I'm just notifying this, just in case someone think there is something useful on the source code OS/2 port.

I don't know how to use IRIT, I just can tell it is a command line tool, but it has some PM app to viewing 3D models (I guess).

Regards
