Comments on: OpenGL/GLUT, Classes (OOP), and Problems http://paulsolt.com/2009/07/openglglut-classes-oop-and-problems/ Putting the Inc back in Solt since 2005.

All I had to do was to download freeglut_std.h from here: http://www.koders.com/c/fid9C884D79DFF686DE5685DF424FC66761EADD7313.aspx?s=freeglut_std.h#L5 and to replace in 3 places "NULL" with "0" in PerformanceTimer.cpp file. Many thanks again! I will check from time to time to see what other goodies you will share :) @Paul Solt

I've also been frustrated a lot by the shear complexity of getting started in OpenGL. Hopefully this is a good starting point and I'll follow up with more documentation. I didn't post the code before, since it was all mangled in my class project and I had to spend a good deal of time cleaning it up for release. There's still things that could be changed, and I plan on updating them in the near future. The code on github is a lot more friendly than the steps that I discussed regarding the static instance. The instance is set from within the framework, instead of requiring the user to set it in their code. You’re welcome.

For programmers it is trivially simple to understand your explanations from this post. I needed to see a full working example; I have to follow trough your code and bring bits and pieces into Code::Blocks, but it is so much easier now! For beginners like me I have a tiny little example following your tutorial with just a very basic opengl instance here: http://ubuntuforums.org/showthread.php?t=1557360 I am not sure why this subject it is not a lot more discussed. Other than your example it is not too much more out there one can learn from. Keep up the good work! Adi @Paul Solt

I'm hosting it on github at: http://github.com/PaulSolt/GLUT-Object-Oriented-Framework I've included an Xcode 3.1 and a Visual Studio 2010 project along with the source files. I'll update the site with more information on using it. The sample will create a simple teapot animation at 60fps. @adrian I just refactored out the code from my animation project.

I've updated my post implementation file to include the line: <pre lang="cpp"> AnimationFramework *AnimationFramework::instance = NULL; </pre> @Steven
Glad to hear. I’ve updated my post implementation file to include the line:

 AnimationFramework *AnimationFramework::instance = NULL;

Had spoken to my professor and he mentioned to add: <pre lang="cpp">Graphics *Graphics::instance;</pre> to the top of my Graphics.cpp file. This did the trick and thankfully got rid of the linker error. Meant to post this awhile ago, but actually fixed the problem. Had spoken to my professor and he mentioned to add:
