I'm really new to OpenGl and wanted to scale a model of the Pyramid of Giza. I wanted to start out with the basic square of your first openGL program. How would I got about modifying this code to the model of the pyramid of Giza? Later on I really want to make it rotate and color it.
#include <GL/glut.h>

void display(void)
{
/* clear all pixels  */
   glClear (GL_COLOR_BUFFER_BIT);

/* draw white polygon (rectangle) with corners at
 * (0.25, 0.25, 0.0) and (0.75, 0.75, 0.0)  
 */
   glColor3f (1.0, 1.0, 1.0);
   glBegin(GL_POLYGON);
      glVertex3f (0.25, 0.25, 0.0);
      glVertex3f (0.75, 0.25, 0.0);
      glVertex3f (0.75, 0.75, 0.0);
      glVertex3f (0.25, 0.75, 0.0);
   glEnd();

/* don't wait!  
 * start processing buffered OpenGL routines 
 */
   glFlush ();
}

void init (void) 
{
/* select clearing color 	*/
   glClearColor (0.0, 0.0, 0.0, 0.0);

/* initialize viewing values  */
   glMatrixMode(GL_PROJECTION);
   glLoadIdentity();
   glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}

/* 
 * Declare initial window size, position, and display mode

 * (single buffer and RGBA).  Open window with "hello"
 * in its title bar.  Call initialization routines.
 * Register callback function to display graphics.
 * Enter main loop and process events.
 */
int main(int argc, char** argv)
{
   glutInit(&argc, argv);
   glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
   glutInitWindowSize (250, 250); 
   glutInitWindowPosition (100, 100);
   glutCreateWindow ("hello");
   init ();
   glutDisplayFunc(display); 
   glutMainLoop();
   return 0;   /* ANSI C requires main to return int. */
}
