glut window
Author
i''ve been told that you can open a gl window in 2 lines using glut. is this true? if so how?
also do the gl drawing commands have to be in a certain function or can that be anywhere. eg on nehe''s site the drawing commands are in the function int DrawGLScene(GLvoid) do they have to be?
hmmm interesting
It''s true taht with glut you can create a glwindow in few lines:
glutInitWindowPosition(0,0); //position of the left bottom corner
glutInitWindowSize(1024,768); // size of the window
glutCreateWindow("Title");// Window Title
Drawing commands can be in other funtion, but this function must be called in the DisplayFunction.
draw_triangle{
glBegin();
glVertex2f(0,0);
glVertex2f(1,0);
glVertex2f(1,1);
}
display_func{ // the display function(or DrawGlScene).
.......
.....
draw_triangle();
....
}
I hope I have answer your question and that you have understood me (my english is not very good)...
glutInitWindowPosition(0,0); //position of the left bottom corner
glutInitWindowSize(1024,768); // size of the window
glutCreateWindow("Title");// Window Title
Drawing commands can be in other funtion, but this function must be called in the DisplayFunction.
draw_triangle{
glBegin();
glVertex2f(0,0);
glVertex2f(1,0);
glVertex2f(1,1);
}
display_func{ // the display function(or DrawGlScene).
.......
.....
draw_triangle();
....
}

thank you lots i''ve been wondering how to do this for ages and your english was good.
hmmm interesting
hmmm interesting
voiddisplay(){ // your code here}intmain( int argc, char** argv ){ glutInit( &argc, argv ); // initializes GLUT glutCreateWindow( "Title" ); // creates a window with the default parameters; glutDisplayFunc( display ); // registers the display function; glutMainLoop(); // gets the ball rolling} More is needed to have something useful, but this will create a window... without barfing.
Allow me to recommend an alternative to glut more sutable for games:
