I have written an article on CodeProject that describes in detail how to create your first GLUI window with some basic controls inside it, and provides you with a template for your OpenGL applications.
When OpenGL applications get more complex, we need something more than a
GLUT mouse, keyboard, and\or popup menus to interact with our OpenGL objects drawn on the window.
GLUI gives us more flexibility by allowing us to add GUI components to interact with our OpenGL objects, such as buttons, check boxes, radio buttons, spinners, list boxes, lists, trees, file browsers, text fields, text areas, and the special controls: rotation and translation.
This article can be used in the following ways:
- Learn how to add GUI components to your OpenGL application in a very straight-forward and simple manner, through
- Interactive Program that displays to the user how every event is handled and classifies these events into GLUT and GLUI events.
- Neat and commented Code that reflects the simplicity of the GLUI library
- Learn some totally new controls in the GLUI library created specifically for graphical manipulation, such as the rotation and translation controls.
- Use the code as a template for your OpenGL applications.
Click below for a screen shot of what the program would look like when its run.
Make sure you read the GLUT Window Template article as a prerequisite to this article. One important thing to note is that GLUI is a C++ library, which means that your code must be written in files with .cpp extension rather than .C, or otherwise the linker will complain.
You can download the code from my GitHub page. Check it out, and let me know what you think.
