 1.利用 glRectf 畫出圖案

    1.使用下列程式碼:

#include <GL/glut.h>
void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glRectf(0.5,0.5,-0.5,-0.5);//四邊形Rectangle
    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();
}






    2.畫出白色身體及紅手臂

#include <GL/glut.h>
void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,0,0);
    glRectf(0.5,0.5,-0.5,-0.5);//白色身體
    glPushMatrix();///要轉動之物體得放在push pop內
        //glTranslatef(x, y, z);
        //glRotatef( angle, 0,0,1 );
        //glTranslatef(x2, y2, z2);
        glColor3f(1,0,0);
        glRectf(0.5,0.5,1.0,0.3);//紅手臂
    glPopMatrix();
    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();
}

    3.使手臂可以隨滑鼠轉動


#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();//重畫畫面

}

void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);
    glRectf(0.5,0.5,-0.5,-0.5);//白色身體
    glPushMatrix();///要轉動之物體得放在push pop內
        glTranslatef(0.5, 0.5, 0);
        glRotatef( angle, 0,0,1 );//2.旋轉他
        glTranslatef(-0.5,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(0.5,0.5,1.0,0.3);//紅手臂
    glPopMatrix();
    glutSwapBuffers();
}
int main(int argc , char **argv){
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    ///glutInitWindowSize(600,600);
    glutCreateWindow("Week13 rect TRT");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);/////mouse
    glutMotionFunc(motion);//配合motion
    glutMainLoop();
}

    4.兩個關節


#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();//重畫畫面
}

void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);
    glRectf(0.3,0.5,-0.3,-0.2);//白色身體
    glPushMatrix();///要轉動之物體得放在push pop內
        glTranslatef(0.3, 0.5, 0);
        glRotatef( angle, 0,0,1 );//2.旋轉他
        glTranslatef(-0.5,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(0.5,0.5,0.8,0.3);//紅手臂
        glPushMatrix();
            glTranslatef(0.8,0.4,0);//3.把下手肘掛在關節上
            glRotatef(angle,0,0,1);//2.旋轉
            glTranslatef(-0.8,-0.4,0);//1.把下手肘的旋轉中心,放在正中心
            glColor3f(0,1,0);//綠色的
            glRectf(0.8,0.5,1.1,0.3);//下手臂
        glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();
}
int main(int argc , char **argv){
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    ///glutInitWindowSize(600,600);
    glutCreateWindow("Week13 rect TRT");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);/////mouse
    glutMotionFunc(motion);//配合motion
    glutMainLoop();
}

    5.兩個關節兩個手臂

#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();//重畫畫面
}
void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);
    glRectf(0.3,0.5,-0.3,-0.2);//白色身體
    glPushMatrix();///right
        glTranslatef(0.3, 0.5, 0);
        glRotatef( angle, 0,0,1 );//2.旋轉他
        glTranslatef(-0.3,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(0.3,0.5,0.8,0.3);//紅手臂
        glPushMatrix();
            glTranslatef(0.8,0.4,0);//3.把下手肘掛在關節上
            glRotatef(angle,0,0,1);//2.旋轉
            glTranslatef(-0.8,-0.4,0);//1.把下手肘的旋轉中心,放在正中心
            glColor3f(0,1,0);//綠色的
            glRectf(0.8,0.5,1.1,0.3);//下手臂
        glPopMatrix();
    glPopMatrix();
    glPushMatrix();///left
        glTranslatef(-0.3, 0.5, 0);
        glRotatef( angle, 0,0,1 );//2.旋轉他
        glTranslatef(0.3,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(-0.3,0.5,-0.8,0.3);//左手臂
        glPushMatrix();
            glTranslatef(-0.8,0.4,0);//3.把下手肘掛在關節上
            glRotatef(angle,0,0,1);//2.旋轉
            glTranslatef(0.8,-0.4,0);//1.把左下手肘的旋轉中心,放在正中心
            glColor3f(0,1,0);//綠色的
            glRectf(-0.8,0.5,-1.1,0.3);//左下手臂
        glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();
}
int main(int argc , char **argv){
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    ///glutInitWindowSize(600,600);
    glutCreateWindow("Week13 rect TRT");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);/////mouse
    glutMotionFunc(motion);//配合motion
    glutMainLoop();
}

    6.各個關節進行轉動

#include <GL/glut.h>
float angle[20],oldx=0;
int angleID=0;
void keyboard(unsigned char key,int x,int y){
    if(key=='0')angleID=0;//右手臂
    if(key=='1')angleID=1;//右手肘
    if(key=='2')angleID=2;//左手臂
    if(key=='3')angleID=3;//左手肘
}

void mouse(int button,int state ,int x,int y){
    oldx=x;
}
void motion(int x,int y){
    angle[angleID]+=(x-oldx);
    oldx=x;
    glutPostRedisplay();//重畫畫面
}

void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);
    glRectf(0.3,0.5,-0.3,-0.2);//白色身體

    glPushMatrix();///right
        glTranslatef(0.3, 0.5, 0);
        glRotatef( angle[0], 0,0,1 );//2.旋轉他
        glTranslatef(-0.3,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(0.3,0.5,0.8,0.3);//紅手臂
        glPushMatrix();
            glTranslatef(0.8,0.4,0);//3.把下手肘掛在關節上
            glRotatef(angle[1],0,0,1);//2.旋轉
            glTranslatef(-0.8,-0.4,0);//1.把下手肘的旋轉中心,放在正中心
            glColor3f(0,1,0);//綠色的
            glRectf(0.8,0.5,1.1,0.3);//下手臂
        glPopMatrix();
    glPopMatrix();

    glPushMatrix();///left
        glTranslatef(-0.3, 0.5, 0);
        glRotatef( angle[2], 0,0,1 );//2.旋轉他
        glTranslatef(0.3,-0.4, 0);//1.把旋轉中心放中心點
        glColor3f(1,0,0);
        glRectf(-0.3,0.5,-0.8,0.3);//左手臂
        glPushMatrix();
            glTranslatef(-0.8,0.4,0);//3.把下手肘掛在關節上
            glRotatef(angle[3],0,0,1);//2.旋轉
            glTranslatef(0.8,-0.4,0);//1.把左下手肘的旋轉中心,放在正中心
            glColor3f(0,1,0);//綠色的
            glRectf(-0.8,0.5,-1.1,0.3);//左下手臂
        glPopMatrix();
    glPopMatrix();

    glutSwapBuffers();
}
int main(int argc , char **argv){
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    ///glutInitWindowSize(600,600);
    glutCreateWindow("Week13 rect TRT");

    glutKeyboardFunc(keyboard);
    glutDisplayFunc(display);
    glutMouseFunc(mouse);/////mouse
    glutMotionFunc(motion);//配合motion
    glutMainLoop();
}
