Type, API. License · X Consortium. Website, FreeGLUT is an open-source alternative to the OpenGL Utility Toolkit (GLUT) library. These kept the API (all gluts functions are usually implemented exactly with the Two of the most common GLUT replacements are OpenGLUT and freeGLUT. It looks to me that Ubuntu has provided everything that the original web site http:// has provided. The api documentation.

Setting one overwrites the other. Game Mode Freeglut seems to only work when the GameMode resolution is set to the full screen. If the application has a single window then this option behaves exactly as the first option. This is achieved with the following functions:.
Freegllut adds the floating-point widths and rounds the final result to return the integer value.

Freeglut calls the frefglut key press callback when the user presses a special key. The glutStrokeLengthf function returns the width in model units of a string of characters in the specified stroke font.
Freeglut does not change the current window or the current menu before invoking the idle callback; programs with multiple windows or menus must explicitly set the current window and current menu and not rely on its current setting.
The callback function has one argument: GLUT considers a window visible if any pixel of the window is visible or any pixel of any descendant window is visible on the screen. The glutWireOctahedron and glutSolidOctahedron functions draw a wireframe and solid octahedron eight-sided Platonic solid respectively.
Freeglut allows the application programmer to specify more direct control over the event loop by means of two new functions. First, the minimum y-coordinate of a window decoration is zero.
It will call any application callback functions as required to process mouse clicks, mouse motion, key presses, and so on. The glutWireCube and glutSolidCube functions draw a wireframe and solid cube respectively. Lastly, to support drawing these objects with shaders, three functions have been added frdeglut which users can provide the addresses of the Coordinate, Normal and Texture Coordinate vertex attribs: The glutMainLoopEvent function causes freeglut to process one iteration’s worth of events in its event loop.
Application programmers should note that if they have specified the “continue execution” action on window closure, freeglut will continue to call the idle callback after the user has closed a window by clicking on the “x” in the window header bar. Finally freeglut allows us to write our own event loop cycle.
FreeGLUT – Wikipedia
Kilgard was releasing updates on a regular basis. The glutSpecialUpFunc function sets the window’s special key release callback.
More functions return the widths of character strings and the font heights, in pixels for bitmapped fonts and in OpenGL units for the stroke fonts. The glutKeyboardUpFunc function sets the window’s key release callback. Two of the corners lie on the positive and negative X-axes. The glutFullScreen function causes the current window to enter fullscreen mode, glutLeaveFullScreen to go back to the window size and position as it was before entering fullscreen mode, and glutFullScreenToggle toggles between fullscreen and normal mode.
The user may specify a smaller width, but the Windows system calls ignore it. Note the “x”, “: The available options are: The glutMainLoop function causes the program to enter the window event loop.
Freeglut calls the callback when there is input from the box dials.
GLUT and FreeGLUT
The coordinates taken by glutInitPosition and glutPositionWindow frewglut, as well as the coordinates provided by FreeGLUT when it calls the glutPositionFunc callback, specify the aip of the non-client area of the window. GLUT however is not free of criticism. If the idle callback renders a particular window this is considered bad form but is frequently done anywaythe programmer should supply a window closure callback for that window which changes or disables the idle callback.
The function returns no value. In here we are going to focus on freeglut. Because the font is a stroke font, the width is actually a floating-point number; the function rounds it to the nearest integer for the freeglut value.
The GLUT library of functions allows an application programmer to create, control, and manipulate windows independent of what operating system the program is running on.
If key repeat is globally switched off through glutSetKeyRepeatit cannot be reenabled on a per-window basis with glutIgnoreKeyRepeat. Freeglut supports two types of font rendering: Freeglut calls these callbacks when the visibility status of a window changes. With freeglut the main loop terminates and the application regains control, hence the printf will be executed.
The glutSpaceballRotateFunc function is implemented in freeglut on X11 only.
