Menbuat Bangun Ruang.

1. Garis Horizontal

#include <GL/glut.h>
#include <stdlib.h>
#define drawOneLine(x1,y1,x2,y2)  glBegin(GL_LINES);  \
   glVertex2f ((x1),(y1)); glVertex2f ((x2),(y2)); glEnd();

void buat(void)
{
   glClear (GL_COLOR_BUFFER_BIT);
   glColor3f (1.0, 1.0, 1.0); /*putih*/
   glBegin (GL_LINES);
       drawOneLine (50.0, 75.0, 250.0, 75.0);
   glEnd();
   glFlush ();
}


void ayey (int w, int h)
{
   gluOrtho2D (0.0, (GLdouble) w, 0.0, (GLdouble) h);
}

int main(int argc, char** argv)
{
   glutInit(&argc, argv);
   glutInitWindowSize (300, 150); 
   glutCreateWindow ("garis");
   glutDisplayFunc(buat); 
   glutReshapeFunc(ayey);
   glutMainLoop();
   return 0;
}

Output 

2. Membuat Persegi 

#include <GL/glut.h>  
void buat(void) 
{ 
     glClear(GL_COLOR_BUFFER_BIT); 
     glBegin(GL_POLYGON);
        glColor3f(1.0, 0.0, 0.0);  /* merah */    
        glVertex2d(0.75,0.75);
        glColor3f(0.0, 1.0, 0.0);  /* hijau */
        glVertex2d(0.75,-0.75);
        glColor3f(0.0, 0.0, 1.0);  /* biru */
        glVertex2d(-0.75,-0.75);
        glColor3f(1.0, 1.0, 1.0);  /* putih */
        glVertex2d(-0.75,0.75);    
     glEnd();
     glFlush(); 
}
  
int main(int argc, char **argv) 
{ 
    glutInit(&argc, argv);
    glutInitWindowSize (300, 300); 
    glutCreateWindow("persegi");
    glutDisplayFunc(buat); 
    glutMainLoop(); 
    return 0; 
}

Output Persegi

 

3. Membuat Segitiga 

#include <GL/glut.h>

#include <math.h> 

void buat(void)

{  

   glClear(GL_COLOR_BUFFER_BIT);  

   glBegin(GL_TRIANGLES);    

  glColor3f(0.0, 0.0, 1.0);  /* biru */    

  glVertex2d(-0.75, -(1*sqrt(3))/2); 

  glColor3f(0.0, 1.0, 0.0);  /* ijo */

  glVertex2d(0.75, -(1*sqrt(3))/2);

  glColor3f(1.0, 0.0, 0.0);  /* merah */       

  glVertex2d(0, (1*sqrt(3))/2);  

   glEnd();  

   glFlush();

} 

   

int main(int argc, char **argv)

{  

   glutInit(&argc, argv);  

   glutInitWindowSize (300, 300); 

   glutCreateWindow("segitiga");  

   glutDisplayFunc(buat);  

   glutMainLoop();  

   return 0;

}

Output Segitiga

4. Membuat Polygon

#include <GL/glut.h>  

void buat(void) 

{ 

   glClear(GL_COLOR_BUFFER_BIT); 

   glBegin(GL_POLYGON);

   glColor3f(0.0,1.5,0.0); /* ijo */

   glVertex2f(0.0,0.75);

   glColor3f(1.0,0.0,0.0); /* merah */

   glVertex2f(-0.5,-0.5);

   glColor3f(0.0,0.0,1.0); /* biru */

   glVertex2f(0.5,-0.5);

   glColor3f(1.0,1.0,0.0); /* kuning */

   glVertex2f(0.75,0.25);

      glColor3f(0.0,1.0,1.0); /* biru langit*/

    glVertex2f(-0.75,0.25);

    glColor3f(1.0,0.0,1.0); /* ungu */

    glVertex2f(-0.5,-0.5);      

  glEnd();

  glFlush(); 

}

  

int main(int argc, char **argv) 

{ 

    glutInit(&argc, argv); 

    glutInitWindowSize (300, 300); 

    glutCreateWindow("polygon");

    glutDisplayFunc(buat); 

    glutMainLoop(); 

    return 0; 

}

Output Polygon
