in reply to Tk & OpenGL

Is there a glpOpenWindow() replacement?

There's a demo script in the OpenGL top level source folder ('test.pl') that gets run as part of 'make test', and provides a rotating cube. Does it run ok for you ?

That script has no mention of glpOpenWindow, or of :old .... afaik, you get your window by calling glutInit() and glutCreateWindow("Window Title").
In fact, the following is all I need to create a window (albeit an empty one):
C:\>perl -MOpenGL=":all" -e "glutInit();glutCreateWindow('Test');sleep + 2;"
Does that 'test.pl' script help you out at all ?

Cheers,
Rob
