 1.複習上禮拜的TRT程式先貼上10行程式再加入正方形的程式，印出正方形身體。

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glRectf(0.5,0.5,-0.5,-0.5);

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("week13_rect_TRT");

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

2.加入1個紅色的手臂準備好TRT的程式

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.5,0.5,-0.5,-0.5);

    glPushMatrix();

    ///glTranslatef(x,y,z);

    ///glRotatef(angle,0,0,1);

    ///glTranslatef(x2,y2,z2);

    glColor3f(1,0,0);

    glRectf(0.5,0.5,1,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

3.把紅色手臂旋轉中心放正心,角度設為45

#include <GL/glut.h>

float angle=45;

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.5,0.5,-0.5,-0.5);

    glPushMatrix();

    ///glTranslatef(x,y,z);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.5,-0.4,0);

    glColor3f(1,0,0);

    glRectf(0.5,0.5,1,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

4.加入滑鼠的函示紅色手臂會隨者滑鼠點擊來揮手

#include <GL/glut.h>

float angle=45, oldX=0;

void mouse(int button,int state,int x,int y){

    oldX=x;

}

void motion(int x,int y){

    angle+=(x-oldX);

    oldX=x;

    glutPostRedisplay();

}

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.5,0.5,-0.5,-0.5);

    glPushMatrix();

    glTranslatef(0.5,0.5,0);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.5,-0.4,0);

    glColor3f(1,0,0);

    glRectf(0.5,0.5,1,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

5.把體瘦身然後手臂貼回身體

#include <GL/glut.h>

float angle=45, oldX=0;

void mouse(int button,int state,int x,int y){

    oldX=x;

}

void motion(int x,int y){

    angle+=(x-oldX);

    oldX=x;

    glutPostRedisplay();

}

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.2);

    glPushMatrix();

    glTranslatef(0.3,0.5,0);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.5,-0.4,0);

    glColor3f(1,0,0);

    glRectf(0.5,0.5,1,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

6.加上綠色下手臂讓綠手臂旋轉

#include <GL/glut.h>

float angle=0, oldX=0;

void mouse(int button,int state,int x,int y){

    oldX=x;

}

void motion(int x,int y){

    angle+=(x-oldX);

    oldX=x;

    glutPostRedisplay();

}

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.2);

    glPushMatrix();

    glTranslatef(0.3,0.5,0);

    ///glRotatef(angle,0,0,1);

    glTranslatef(-0.3,-0.4,0);

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

    glRectf(0.3,0.5,0.8,0.3);

    glPushMatrix();

    glTranslatef(0.8,0.4,0);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.8,-0.4,0);

    glColor3f(0,1,0);

    glRectf(0.8,0.5,1.1,0.3);

    glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}

7.把右半邊手臂複製程式碼換成左臂

#include <GL/glut.h>

float angle=0, oldX=0;

void mouse(int button,int state,int x,int y){

    oldX=x;

}

void motion(int x,int y){

    angle+=(x-oldX);

    oldX=x;

    glutPostRedisplay();

}

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.2);

    glPushMatrix();

    glTranslatef(0.3,0.5,0);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.3,-0.4,0);

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

    glRectf(0.3,0.5,0.8,0.3);

    glPushMatrix();

    glTranslatef(0.8,0.4,0);

    glRotatef(angle,0,0,1);

    glTranslatef(-0.8,-0.4,0);

    glColor3f(0,1,0);

    glRectf(0.8,0.5,1.1,0.3);

    glPopMatrix();

    glPopMatrix();

    glPushMatrix();

    glTranslatef(-0.3,0.5,0);

    glRotatef(angle,0,0,1);

    glTranslatef(0.3,-0.4,0);

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

    glRectf(-0.3,0.5,-0.8,0.3);

    glPushMatrix();

    glTranslatef(-0.8,0.4,0);

    glRotatef(angle,0,0,1);

    glTranslatef(0.8,-0.4,0);

    glColor3f(0,1,0);

    glRectf(-0.8,0.5,-1.1,0.3);

    glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(300,300);

    glutCreateWindow("week13_rect_TRT");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}
