作業二

1. 程式碼

#include<GL/glut.h>  //標頭檔

void display()

{

    glBegin(GL_POLYGON);

       glColor3f(1,1,0);//顏色

       glVertex3f(0.0,0.0,0.0);//點1

       glVertex3f(1.0,0.0,0.0);//點2

       glVertex3f(1.0,1.0,0.0);//點3

     glEnd();

   //glutSolidTeapot(0.3);

     glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc, argv);  //引入程式

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);  //雙視窗

    glutCreateWindow("hello 3D");  //視窗名稱

    glutDisplayFunc(display);  //展示

    glutMainLoop();

}
