#include<iostream>

#include <GL/glut.h>

using namespace std;

GLsizei winWidth = 600, winHeight = 600;




void init()
{
    glClearColor(1.0, 1.0, 1.0, 0.0);

}

void displayWirePolyhedra()
{
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(0.0, 0.0, 1.0);

    gluLookAt(5.0, 5.0, 5.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);

    glScalef(1.5, 2.0, 1.0);
    glutWireCube(1.0);

    glScalef(0.8, 0.5, 0.8);
    glTranslatef(-6.0, -5.0, 0.0);
    glutWireDodecahedron();

    glTranslatef(8.6, 8.6, 2.0);
    glutWireTetrahedron();

    glTranslatef(-3.0, -1.0, 0.0);
    glutWireOctahedron();

    glScalef(0.8, 0.8, 1.0);
    glTranslatef(4.3, -2.0, 0.5);
    glutWireIcosahedron();

    glFlush();
}

void winReshapeFcn(GLint newWidth, GLint newHeight)
{
    glViewport(0, 0, newWidth, newHeight);

    glMatrixMode(GL_PROJECTION);
    glFrustum(-1.0, 1.0, -1.0, 1.0, 2.0, 20.0);

    glMatrixMode(GL_MODELVIEW);

    glClear(GL_COLOR_BUFFER_BIT);
}

int main(int argc, char* argv[])
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);
    glutInitWindowPosition(100, 100);

    glutInitWindowSize(winWidth, winHeight);
    glutCreateWindow("立方体");
    init();
    glutDisplayFunc(displayWirePolyhedra);
    glutReshapeFunc(winReshapeFcn);
    glutMainLoop();

    system("pause");
    return 0;
}

运行结果：
