Togl is a Tk widget for OpenGL rendering.
I have ported part of Togl to OS/2 using the PGL API in order to develop my CS 488 assignments at home. I have only ported the RGB parts of Togl, and not the colour index modes, and not other features of Togl.
In Togl, versions for Windows and X exist simultaneously in the source file. In my port I added an EMX version, so all three versions exists simultaneously in the source file. I have not tested this version under Windows, so it is possible I accidently broke that part of it. I have done marginal testing of the X code in Togl.
Source for Togl 1.5 for OS/2 is available to download in zip file format.
Example code that uses Togl is available from the CS 488/688 website.
First you will need Tcl/Tk for OS/2. My port for Togl has only been tested on the 8.0.5 beta version of Tcl/Tk, and probably will not work with the 7.6/4.2 release.
As part of the source code, I need tkOS2Int.h from the source files for Tcl/Tk. If you use a newer version of Tcl/Tk, this file may need to be replaced.
Warning: Togl 1.5 for OS/2 uses internal code from Tcl/Tk 8.0.5 (tkOS2Int.h), and therefore it is subject to change. So be careful out there.
OpenGL for OS/2 Warp is available by FTP from IBM. I suggest downloading oglgold.zip.
Togl is used to develop programs. So you will of course need a compiler. Togl compiles under emx and gcc.
The C interface and Tcl/Tk interface for Togl are described at the Togl homepage.
Many features of Togl probably do not work. But my assignments for my CS 488 run fine, and that is all I wanted. If you want to port more features of Togl, go right ahead.
