讓紅綠杯子旋轉

#include <GL/glut.h>

float angle =0;

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(0,1,0);

    glPushMatrix();

        glTranslatef(0.8,0,0);

        glRotatef(angle,0,0,1);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

        glColor3f(1,0,0);

    glPushMatrix();

        glRotatef(angle,0,0,1);

        glTranslatef(0.8,0,0);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

    angle++;

}

int main(int argc, char* argv[] )

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}
