These commands are provided by GLUT (the OpenGL Utility Toolkit). GLUT provides commands to create windows, subwindows, and menus; and to handle . The OpenGL programming world owes a tremendous debt to Mr. Mark J. Kilgard for writing the OpenGL Utility Toolkit, or GLUT. The GLUT library of functions. Now that we have a static image on the screen, we want to move to the next step. A changing image. We can specify a function for. GLUT to use.

For all these platforms, the procedure is roughly the same: The glutSetKeyRepeat and glutIgnoreKeyRepeat functions set whether repeated key presses generated by keeping a key depressed are passed on to the keyboard callbacks. The glutVisibilityFunc and the glutWindowStatusFunc functions set the window’s visibility and windowStatus callbacks for the current window.

Most windows have a usable tutlrial surrounded by a border and with a title bar on the top. The Freegluf key is considered to be a regular key. Users who find differences should contact the freeglut Programming Consortium to have them fixed.

The glutWireOctahedron and glutSolidOctahedron functions draw a wireframe and solid octahedron eight-sided Platonic solid respectively.

GLUT Tutorial – Source Code and Projects »

You will see a Tutorials. Kilgard was releasing updates on a regular basis.

Function to leave fullscreen window freegltu, glutLeaveFullScreenor to toggle between fullscreen and normal window mode, glutFullScreenTogglehave been added. Freeglut calls the idle callback when there are no inputs from the user. The glutInitWindowPosition and glutInitWindowSize functions specify a desired position and size for windows that freeglut will create in the future.


This is a feature of freeglut and can tutorisl adjusted if so desired. It’s not mentioned before Tutorial 02, but it can cause flickering, so it’s there nonetheless. He should also be prepared to assist in the implementation. If you just want one title for the window over the window’s entire life, you should set it when you open the window with glutCreateWindow.

Because the font is bitmapped, the width is an exact integer. Before the first call to glutStrokeCharacter the application program should call the OpenGL transformation positioning and scaling functions to set the position of the character in the window.

GLUT Tutorial

Freeglut calls the key release callback when the user releases a tutoriak. Freeglut calls glRasterPos4v to advance tutoriao cursor by the width of a character and to render carriage returns when appropriate. You should run the tutorials directly from the right directory: If the window status callback for a window is disabled and later re-enabled, the window status of the window is undefined; any change in window window status will be reported, that is if you disable a window status callback and re-enable the callback, you are guaranteed the next window status change will be reported.

In the first case, the closure callback is not invoked from the glutDestroyWindow call, but at a later time point. Notice that it can be anywhere, not necessarily in the same folder. The other functions render the teacup and teaspoon he used in the table scene figure in his PhD thesis. Your Visual Studio project is now created.


Kilgard stopped supporting the GLUT library inhaving moved on to bigger and better things, this started to become a problem. And this concludes our first tutorial! GLUT really makes things simple, hence it is very usefull to learn and to build small applications. You can now debug the code by pressing F5.

Freeglut calls the special key press callback when the user presses a special key. Another difficulty with GLUT, especially with multiple-window programs, is that if the user clicks on the “x” in the window header the application exits immediately.

When FreeGLUT calls this callback, it provides the new position on the screen of the top-left of the non-client areathat is, the same coordinates used by glutInitPosition and glutPositionWindow. The glutBitmapHeight function returns the height of a character in the specified bitmap font. The freeglut Programming Consortium January, Since the freeglut library was developed in order to update GLUT, it is natural that there will be some differences between the two.
