### Test.cpp ### DONT WORK


Car car;
void display()
{
	glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
	car.draw(3.6, 2.4, 2.4);
	glFlush();
	glutSwapBuffers();
}

void init()
{
	...
}

int main(int argc, char **argv)
{
	...
	glutDisplayFunc(display);
	init();
	glutMainLoop();
	return 0;
}

### Test.cpp ### WORKS

	car->draw(3.6, 2.4, 2.4);
	glFlush();
