Contoh Program C++ || Mobil 3D With C++

Posting kali ini tentang mata kuliah grafika komputer, tugasnya adalah membuat mobil 3D menggunakan OpenGL, berikut Code nya.
kalau ada kesalahan harap maklum soalnya masih SMK bocah gitu lah...... 

Berikut Contoh Outputnya:

#include <glut.h>
#include <math.h>

void kerucut(float ngisor, float nduwur, float dowo);
void blok(float tebal,int ratiol,int ratiop);
