Frank and I lust for OpenGL. But tcl/tk sure is handy. So:<br><br> <a href="http://togl.sourceforge.net/">http://togl.sourceforge.net/</a> (requiring C programmin)<br> and <a href="http://www.tcl3d.org/">http://www.tcl3d.org/
</a> (full Tcl scriptability)<br><br>The problem with the latter is that, even with OpenGL display lists (don't ask) I think this is more traffic than we want to send over a pipe to get wicked high frame rates. And with Tcl as a separate process we cannot get to the OpenGL context from LTk.
<br><br>Right now Frank is trying to get an interpreter running within CL. I sent him some sample C code from Welch & Jones "Practical Programming in Tcl and Tk". Just writing to ask if there is any expertise on this list for embedding Tk.
<br><br>Oh, and does this sound right? Is this a typical time when folks cross over from using a pipe and switch to a C interface? Note that this is a middle ground, because most work is still done by building Tcl/tk commands and eval-ing them, but now we are running in the same process so, for example, we can use cl-opengl to build a display list which can be invoked by a Tk glCallList. I hope. :)
