Tk and 3d objects

Good time of the day,

I need to embed graphs (lines, polygons, curves) on 3d space
(oblique coordinate system preferred) within a frame of a Tk
application.

I studied Tk::Zinc as well as the chapter from O'Reilly PerlTk
book that is available online.

It seems that Tk::Zinc doesn't provide the interface to OpenGL
3d functions, and O'Reilly book doesn't offer solutions to
embedding the OpenGL applets within a frame, but rather in
a separate window. (I tried to apply a code similar to their
example, but it failed).

Am I wrong somewhere, and one of the above ways does work for
my case? And if I am right, which other solutions could you
recommend, aside from writing a manual 3d <-> 2d transformation
and plotting the 3d pictures on a canvas by myself?

Roman.

I haven't tried it, but when I understand it correct, you can send the
window-id you want to use to openGL.

Since you seem to have read Mastering PerlTk, The OpenGL example has one
line:

glpOpenWindow(parent => hex($top->id), widht=>450, height => 450);

You should try using $frame->id instead of $top->id to embed it into a
self-defined frame, not a toplevel.

I haven't the OpenGL module installed, so I cannot test it easily. It
would be nice to hear if my understanding of X-Windows is correct, and
if this is working on MS-platforms, too.

Best regards,

Heiko

I havn't been able to get the OpenGL module to install without error.

perl-SDL ( the perl port to the SDL library) does OpenGL pretty well.
There are some demos in the SDL_Perl_2.1.0 distribution, and it has a
little tutorial available.

Maybe you could insert the SDL into a window in a Tk widget.
