hey i was wondering if there was a way to display a white square on an all-black blackground, in full-screen (with no mouse pointer showing, etc.). does anyone know of a really quick simple way? using openGL.

To get a black background:

glClearColor(0,0,0,0);

glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);


Switch to an orthogonal projection matrix (means 2d mode):
glMatrixMode(GL_PROJECTION);
glPushMatrix();
glLoadIdentity();
glOrtho(0,screen_width,screen_height,0,-1,1);
glMatrixMode(GL_MODELVIEW);



If you want a filled square use glBegin(GL_QUADS) and glVertex2i to render a square quad


If you don't want your square filled use glBegin(GL_LINES) and glVertex2i to draw 4 lines forming a square.


To disable the mouse cursor in windows:
ShowCursor(false);

For info about setting up opengl go to NeHe
