如何使用OPENGL绘制立方体

#include void display() { glClear(GL_COLOR_BUFFER_BIT); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(1.0,1.0,1.0,0.0,0.0,0.0,0.0,1.0,0.0); glutWireCube(0.5); glutSwapBuffers(); } void reshape(int w,int h) { glViewport(0,0,w,h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-4.0,4.0,-4.0,4.0,-4.0,4.0); } void init() { glClearColor(1.0,1.0,1.0,1.0); glColor3f(0.0,0.0,0.0); } int main(int argc,char** argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); glutInitWindowSize(500,500); glutInitWindowPosition(0,0); glutCreateWindow("cube"); glutReshapeFunc(reshape); glutDisplayFunc(display); init(); glutMainLoop(); }
