現在是所有關節都會一起動，目標是可自己選擇關節動
所以關節的角度要分開!!!
float angle=0;只有一個關節
float angle[20];就有20個關節

#include <GL/glut.h>
float angle[20],oldX=0;
int angleID=0;///0:第0個關節，1:第一個關節，2:第二個關節
void keyboard(unsigned char key,int x,int y)
{
    if(key=='0')angleID=0;///預設這是第一個
    if(key=='1')angleID=1;
    if(key=='2')angleID=2;
    if(key=='3')angleID=3;
}
void mouse(int button, int state , int x, int y)///mouse按下去
{
    oldX = x;
}
void motion(int x,int y)
{
    angle[angleID] += (x-oldX);
    oldX=x;
    glutPostRedisplay();
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白色的
    glRectf(0.3,0.5,-0.3,-0.2);///身體,瘦身
    glPushMatrix();///右半邊，掛的位置也改了
        glTranslatef(0.3,0.5,0);///等下要掛在0.5,0.5
        glRotatef(angle[0],0,0,1);///(2)旋轉
        glTranslatef(-0.3,-0.4,0);///(1)先把旋轉中心放正中心
        glColor3f(1,0,0);///紅色的
        glRectf(0.3,0.5,0.8,0.3);///右上手臂
        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)再畫下手肘
        glColor3f(0,1,0);///綠色的
        glRectf(0.8,0.5,1.1,0.3);///再畫右下手肘
        glPopMatrix();
    glPopMatrix();

    glutSwapBuffers();
