下載好之後，觀察更鰾順序後是否有什麼改變

↑ 改變前是自轉 ↑

↑ 改變後是公轉 ↑

做好前置作業，你知道的

做個茶壺

程式碼：

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10-TRT");

    glutDisplayFunc(display);

    glutMainLoop();

}

加個煙

程式碼：

#include <GL/glut.h>

float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef(0,0.5,0);
        glutWireTeapot(0.3);
    glPopMatrix();
    glPushMatrix();
        glTranslatef(0.51,0.64,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);
        glutWireCone(0.1,0.6,10,10);
    glPopMatrix();
    glutSwapBuffers();

}
void motion(int x,int y)
{
    angle = x;
    display();
}

int main(int argc, char ** argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week10-TRT");

    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutMainLoop();
