Delphi(Pascal) code

 glBegin(GL_POLYGON);      //前表面     glColor3f(1.0,1.0,1.0);     glVertex3f(5,5,5);     glColor3f(1.0,1.0,0);     glVertex3f(5,-5,5);     glColor3f(1.0,0,0);     glVertex3f(-5,-5,5);     glColor3f(1.0,0,1.0);     glVertex3f(-5,5,5);   glEnd;   glBegin(GL_POLYGON);      //后表面     glColor3f(0,1.0,1.0);     glVertex3f(5,5,-5);     glColor3f(0,1.0,0);     glVertex3f(5,-5,-5);     glColor3f(0.0,0,0);     glVertex3f(-5,-5,-5);     glColor3f(0,0,1.0);     glVertex3f(-5,5,-5);   glEnd;   glBegin(GL_POLYGON);      //上表面     glColor3f(0,1.0,1.0);     glVertex3f(5,5,-5);     glColor3f(1.0,1.0,1);     glVertex3f(5,5,5);     glColor3f(1.0,0,1);     glVertex3f(-5,5,5);     glColor3f(0,0,1.0);     glVertex3f(-5,5,-5);   glEnd;      glBegin(GL_POLYGON);      //下表面     glColor3f(0,1.0,0);     glVertex3f(5,-5,-5);     glColor3f(1.0,1.0,0);     glVertex3f(5,-5,5);     glColor3f(1.0,0,0);     glVertex3f(-5,-5,5);     glColor3f(0,0,0.0);     glVertex3f(-5,-5,-5);   glEnd;   glBegin(GL_POLYGON);      //左表面     glColor3f(1,1.0,1.0);     glVertex3f(5,5,5);     glColor3f(0.0,1.0,1);     glVertex3f(5,5,-5);     glColor3f(0.0,1,0);     glVertex3f(5,-5,-5);     glColor3f(1,1,0.0);     glVertex3f(5,-5,5);   glEnd;   glBegin(GL_POLYGON);      //右表面     glColor3f(1,0.0,1.0);     glVertex3f(-5,5,5);     glColor3f(0.0,0.0,1);     glVertex3f(-5,5,-5);     glColor3f(0.0,0,0);     glVertex3f(-5,-5,-5);     glColor3f(1,0,0.0);     glVertex3f(-5,-5,5);   glEnd;
