 1.https://jsyeh.org/3dcg10/

下載win、data

跑Transformation.exe 右鍵切換Swap(也可按S鍵切換)

2.https://120.125.80.50/GL/opengl_TRT_demo.html

右下ToDraw開始畫圖

myDrawObject(0);移到下面的glTranslatef(0,0,0);下面

點擊右上angle並按空白鍵，圖片進行旋轉

myDrawObject(0);移到上面的glTranslatef(0,0,0);下面

按住glTranslatef(0,0,0);可以拖曳圖案

3.茶壺逆時鐘一直旋轉

#include <GL/glut.h>

float angle=0;

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0, 0, 1);///旋轉

        glTranslatef(0.4, -0.07, 0);///往右下移動

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

    angle+=0.1;

 }

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week12");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

4.紅色茶壺掛在白茶壺上旋轉

#include <GL/glut.h>

float angle=0;

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1, 1, 1);///白色

    glutSolidTeapot(0.3);

    glPushMatrix();

        glTranslatef(0, 0, 0);///下面旋轉中的東西掛在某處

        glRotatef(angle, 0, 0, 1);///旋轉

        glTranslatef(0.2, 0, 0);///往右下移動

        glColor3f(1, 0, 0);///紅色

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

    angle+=0.1;

 }

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week12");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

5.揮舞"手臂"

#include <GL/glut.h>

float angle=0;

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1, 1, 1);///白色

    glutSolidTeapot(0.3);

    glPushMatrix();

        glTranslatef(0.3, 0, 0);///下面旋轉中的東西掛在某處

        glRotatef(angle, 0, 0, 1);///旋轉

        glTranslatef(0.2, 0, 0);///往右下移動

        glColor3f(1, 0, 0);///紅色

        glutSolidTeapot(0.2);

        glPushMatrix();

            glTranslatef(0.2, 0, 0);

            glRotatef(angle, 0, 0, 1);///旋轉

            glTranslatef(0.2, 0, 0);///往右下移動

            glColor3f(1, 0, 0);///紅色

            glutSolidTeapot(0.2);

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

    angle+=0.1;

 }

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week12");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}
