OK, I feel pretty embarrassed everytime I write something here, because I know that my programming knowledge of pool is very shallow.... but nonetheless.
That's life... so I live with it.
So I realized that for glTranslatef, I just had to add z in the brackets. OK good.
Now for snpirntf, I also realized that it requires stdio.h header file, and on top of that the command seem to be _snprintf and not just snprintf, so I made that change as well.
Here is the error now:
'_snprintf': cannot convert parameter 1 from 'char (*)[40]' to 'char *'
Mike, I understand your frustration on me but... be nice...
C++ openGL : Lag issue
Quote:'_snprintf': cannot convert parameter 1 from 'char (*)[40]' to 'char *'
So can you show me the line where you use it, and the line where you declare the buffer?

I was being nice. I was giving you the knowledge on how to find the solutions/answers to your questions yourself. This is by far more useful then spoon feeding you the answers which won't really help you learn.
There are times to post questions here and you should never feel embarassed about doing so, even for very basic one. We all start someplace. Just wish I had a site like this when I first started programming. But sometimes replies can take, hours, days or just never come to certain questions. This can be frustrating and discouraging.
Some people don't know about the help feature(s), or how to use MSDN/google to effectively search for answers. So I was merely pointing out resources to help you, help yourself, in the future.

There should not be an '&' before that parameter in the code you were shown. :)

Oops. Let me fix that so nobody knows it was my fault :D

OK everyone.
Thanks for the help... especially erissian.
The text rendering works great and looks great.
However, I don't think the drawing list is working properly, as I don't see anything on the screen anymore...
No error or warning on the code... so I'm not sure what the problem is...
Here's my source code. (lot shorter!0

You build your list before initializing GL. Put that snippet right before glutMainLoop().
Wait, it's not even there anymore! That can't help :)
Also, take advantage of that text function!
Ok, so you did!
Edit: No fair changing things when I'm not looking!

Ooops I sourced the wrong code - that one is the version W/O the display list.
Here is the correct one.
This one does show me a few circles, but not every circle.
I have to look in further to see what is going on but mean while I guess you could have a look as well.
Cheers!

I have to look in further to see what is going on but mean while I guess you could have a look as well.

OK - so the reason why there's only a few circles showing, is because I forgot to edit one of the section (GL_TRIANGLE_FAN is still being used there).
So when I update that part with display list, there is essentially no circles.
Only lines and text are rendered - and the rendering is done only once.
Initially, when I press 't', this would trigger the timer and I was able to see the flow. But pressing 't' now doesn't do anything - the timer stays still.

It's hard to tell from what I can see, but it looks like GeometryFlag is related to front(), and the only call to it in the render function is commented out. What is front()?
