1.先打開codeblack，建立一個project ，建立一個Console appliction

(這是一開始的程式碼，要刪光)

2.要印出20個Hello World

-------------(程式碼)-----------------

#include <stdio.h> ///(0)

FILE * fout=NULL; ///(1) 宣告檔案指標變數

int main()

{

fout = fopen("filename.txt", "w+"); ///(2)開檔案，等一下要寫

for(int i=0;i<20;i++){

fprintf( fout, "Hello World\n"); ///(3)

}

(可以在一開始建的這個程式的資料夾

找到filename.txt然後打開後就是20個Hello World)

3.印出motion

-------------(程式碼)-----------------

#include <stdio.h> ///(0)

FILE * fout=NULL; ///(1) 宣告檔案指標變數

float angle[20];

int main()

{

fout = fopen("motion.txt", "w+"); ///(2)開檔案，等一下要寫

for(int i=0;i<20;i++){

fprintf( fout, " %.1f", angle[i]); ///要小心，沒有空格，就會失敗

}

(會印出整齊的0.0 0.0 0.0 0.0)

❤要統整之前教的功能做機器人❤

4.先開啟freeglut windows網站
https://www.transmissionzero.co.uk/software/freeglut-devel/

然後下載Download freeglut 3.0.0 for MinGW ，

然後解壓縮然後打開lib資料夾，複製貼上libfreeglut.a，把複製的改名為libglut32.a

5.打開codeblack，建立一個project，然後建立glut開啟執行

(把原本的程式碼刪光光)

6.把老師在http://120.125.89.81/給的程式碼step02-2.cpp貼上

-------------(程式碼)-----------------

#include <GL/glut.h>

float angle[20];///NOW

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();///body

glColor3f(1,1,1);///white

glutSolidTeapot( 0.3 );///body

glPushMatrix();///right Arm

glTranslatef(0.18, 0, 0);///(3)掛到肩上

glRotatef(angle[1], 0,0,1);///(2)轉動 ///NOW

glTranslatef(0.18, 0, 0);///(1)改變旋轉中心,放到中心

glColor3f(1,0,0);///red

glutSolidTeapot( 0.2 );///right upper arm

glPopMatrix();

glutSwapBuffers();

}

int oldX;///NOW

void mouse(int button, int state, int x, int y)///NOW

{

}

void motion(int x, int y)///NOW

{

display();///NOW

}

int main(int argc, char**argv)

{

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

///glutInitWindowSize(600,600);///我們可以開很大的視窗

glutCreateWindow("week 13 motion TRT angle file");

glutMouseFunc(mouse);///NOW

glutMotionFunc(motion);///NOW

glutDisplayFunc(display);

glutMainLoop();

}

(紅色茶壺=手，是可以轉動的)

7.在codeblack貼上程式碼並執行(水壺+(2個小水壺)手臂->用滑鼠控制)

-------------(程式碼)-----------------

#include <GL/glut.h>

float angle[20];///NOW

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();///body

glPushMatrix();///right Arm

glTranslatef(0.18, 0, 0);///(3)掛到肩上

glRotatef(angle[1], 0,0,1);///(2)轉動 ///NOW

glTranslatef(0.18, 0, 0);///(1)改變旋轉中心,放到中心

glColor3f(1,0,0);///red

glutSolidTeapot( 0.2 );///right upper arm

glPushMatrix();///NOW2 長出下手臂

glTranslatef(0.18, 0, 0);///(3)掛到肘上

glRotatef(angle[1], 0,0,1);///(2)轉動 ///NOW

glTranslatef(0.18, 0, 0);///(1)改變旋轉中心,放到中心

glColor3f(1,0,0);///red

glutSolidTeapot( 0.2 );///right lower arm

glPopMatrix();

glutSwapBuffers();

}

int oldX;///NOW

void mouse(int button, int state, int x, int y)///NOW

{

oldX = x;///NOW

}

void motion(int x, int y)///NOW

{

angle[1] += (x-oldX);///NOW

oldX = x;///NOW

display();///NOW

}

int main(int argc, char**argv)

{

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

///glutInitWindowSize(600,600);///我們可以開很大的視窗

glutCreateWindow("week 13 motion TRT angle file");

glutMouseFunc(mouse);///NOW

glutMotionFunc(motion);///NOW

glutDisplayFunc(display);

glutMainLoop();

}

8.在codeblack貼上程式碼並執行(水壺+(2個小水壺)2隻手臂->用滑鼠控制)

-------------(程式碼)-----------------
