Week 2 _

- Review Week1 -

複習上星期的課程

- GLUT Teapot -

把GLUT的程式碼改成

#include <GL/glut.h>

void display()

{

    glColor3f(0,0,1);

    glutSolidTeapot(0.3);//畫出茶壺

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Week2");

    glutDisplayFunc(display);

    glutMainLoop();

}

- GLUT Shapes -

- GLUT Polygon -

把GLUT的程式碼改成

#include <GL/glut.h>

void display()

{

    glBegin(GL_POLYGON); //畫出凸多邊形

        glColor3f(0,0,1);glVertex2f(1,0);

        glColor3f(0,1,0);glVertex2f(-1,-1);

        glColor3f(1,0,0);glVertex2f(-1,1);

    glEnd();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Week2");

    glutDisplayFunc(display);

    glutMainLoop();

}
