Togl 1.5

   [1]Togl is a [2]Tk widget for OpenGL rendering.
   
   I have ported part of Togl to OS/2 using the PGL API in order to
   develop my [3]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.
   
How to get Togl 1.5 for OS/2

   Source for Togl 1.5 for OS/2 is available to [4]download in zip file
   format.
   
   [5]Example code that uses Togl is available from the [6]CS 488/688
   website.
   
How do I use Togl 1.5 for OS/2

  System Requirements
  
    Tcl/Tk
    
   First you will need [7]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
    
   OpenGL for OS/2 Warp is available by [8]FTP from IBM. I suggest
   downloading [9]oglgold.zip.
   
    Compiler
    
   Togl is used to develop programs. So you will of course need a
   compiler. Togl compiles under [10]emx and gcc.
   
  Interface
  
   The [11]C interface and [12]Tcl/Tk interface for Togl are described at
   the [13]Togl homepage.
   
Bugs

   Many features of Togl probably do not work. But my assignments for my
   [14]CS 488 run fine, and that is all I wanted. If you want to port
   more features of Togl, go right ahead.
