下載MinGW的 "Download freeglut 3.0.0 for MinGW"
03 撰寫程式碼，試試看作關節移動、旋轉
程式碼：
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f( 255 , 255 , 255 ); ///白色
glutSolidTeapot( 0.3 ); ///身體
///右手臂
glPushMatrix();
glTranslatef( 0.2 , 0 , 0 ); ///(3)往右移動，掛在身體的右肩
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( 0.28 , 0 , 0 ); ///(1)往右推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
///右下手臂
glPushMatrix();
glTranslatef( 0.2 , 0 , 0 ); ///(3)往右移動，掛在身體的右肘
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( 0.28 , 0 , 0 ); ///(1)往右推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
glPopMatrix();
glPopMatrix();
///左手臂
glPushMatrix();
glTranslatef( -0.2 , 0 , 0 ); ///(3)往左移動，掛在身體的左肩
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( -0.28 , 0 , 0 ); ///(1)往左推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
///左下手臂
glPushMatrix();
glTranslatef( -0.2 , 0 , 0 ); ///(3)往左移動，掛在身體的右肘
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( -0.28 , 0 , 0 ); ///(1)往左推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
angle++;
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week11");
glutIdleFunc(display);
glutDisplayFunc(display);
glutMainLoop();
}
04 使用滑鼠點，選改變茶壺旋轉
程式碼：
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f( 255 , 255 , 255 ); ///白色
glutSolidTeapot( 0.3 ); ///身體
///右手臂
glPushMatrix();
glTranslatef( 0.2 , 0 , 0 ); ///(3)往右移動，掛在身體的右肩
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( 0.28 , 0 , 0 ); ///(1)往右推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
///右下手臂
glPushMatrix();
glTranslatef( 0.2 , 0 , 0 ); ///(3)往右移動，掛在身體的右肘
glRotatef( angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( 0.28 , 0 , 0 ); ///(1)往右推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
glPopMatrix();
glPopMatrix();
///左手臂
glPushMatrix();
glTranslatef( -0.2 , 0 , 0 ); ///(3)往左移動，掛在身體的左肩
glRotatef( -angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( -0.28 , 0 , 0 ); ///(1)往左推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
///左下手臂
glPushMatrix();
glTranslatef( -0.2 , 0 , 0 ); ///(3)往左移動，掛在身體的右肘
glRotatef( -angle , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( -0.28 , 0 , 0 ); ///(1)往左推，把茶壺的柄放到中心，變轉動軸
glColor3f( 255 , 0 , 0 ); ///紅色
glutSolidTeapot( 0.2 ); ///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
///angle++; NOW2!!
}
void motion(int x,int y) ///NOW2!!!
{
angle = x ;
display(); ///NOW2!!!
}
int main(int argc, char**argv)
{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week11");
glutIdleFunc(display);
glutDisplayFunc(display);
glutMotionFunc(motion); ///NOW2!!!
glutMainLoop();
}
05 按鍵控制轉動哪隻手 & 手肘
程式碼：
#include <GL/glut.h>
float angle1=0 , angle2 , angle3 , angle4 ; ///NOW3~~~
int jointID=1; ///1,2,3,4 ///NOW3~~~
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f( 255 , 255 , 255 ); ///白色
glutSolidTeapot( 0.3 ); ///身體
///右手臂
glPushMatrix();
glTranslatef( 0.2 , 0 , 0 ); ///(3)往右移動，掛在身體的右肩
glRotatef( angle1 , 0 , 0 , 1 ); ///(2)旋轉
glTranslatef( 0.28 , 0 , 0 ); ///(1)往右推，把茶壺的柄放到中心，變轉動軸

glutCreateWindow("week11");
glutIdleFunc(display);
