一開始先把老師給檔案開啟

可以看到下面的畫面

為了讓關節可以旋轉

如是加入了一些程式

於是當我們按下1 ，2，3，4時

就可以旋轉不同的部位。

#include <GL/glut.h>

float angle=0, oldX=0, oldY=0;

void drawBody(){

glPushMatrix();

glScalef(1, 0.5, 0.5);

glutSolidCube(1);

glPopMatrix();

}

void drawArm(){

glPushMatrix();

glScalef(0.6, 0.3, 0.3);

glutSolidCube(1);

glPopMatrix();

}

float angle1=0,angle2=0,angle3=0,angle4=0;

void display()

{

{ ///Lighting

glColor3ub(166,132,100);

GLfloat pos[]={0, 0, -1, 0};

glLightfv(GL_LIGHT0, GL_POSITION, pos);

glEnable(GL_LIGHT0);

//glEnable(GL_LIGHTING);

glEnable(GL_DEPTH_TEST);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

}

glPushMatrix();

glTranslatef(0.5, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上掛上去 ver 4

glRotatef(angle1, 0,0,1);///把下面整團, 都對中間做旋轉 ver 3

glTranslatef(0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2

drawArm();///這是個Arm ver 1 Right Upper Arm

glPushMatrix();

glTranslatef(0.25, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上掛上去 ver 4

glRotatef(angle2, 0,0,1);///把下面整團, 都對中間做旋轉 ver 3

glTranslatef(0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2

drawArm(); ///Right Lower Arm

glPopMatrix();

glPushMatrix();

glTranslatef(-0.5, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上掛上去 ver 4

glRotatef(-angle3, 0,0,1);///把下面整團, 都對中間做旋轉 ver 3

glTranslatef(-0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2

drawArm();///這是個Arm ver 1 Left Upper Arm

glPushMatrix();

glTranslatef(-0.25, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上掛上去 ver 4

glRotatef(-angle4, 0,0,1);///把下面整團, 都對中間做旋轉 ver 3

glTranslatef(-0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2

drawArm(); ///Left Lower Arm

glPopMatrix();

drawBody();

glFlush();

}

void Keyboard(unsigned char key,int x, int y)

{

if(key=='1') angle1++;

if(key=='2') angle2++;

if(key=='3') angle3++;

if(key=='4') angle4++;

}

void motion(int x, int y)

{ angle -= y - oldY;

oldY=y; oldX=x;

}

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

if(state==GLUT_DOWN) { oldX=x; oldY=y; }

}

void timer(int t)

{

glutTimerFunc(20, timer, t+1);

//angle++;

glutPostRedisplay();

}

int main(int argc, char**argv)

{

glutInit(&argc, argv);

glutCreateWindow("T-R-T test");

glutDisplayFunc(display);

glutTimerFunc(20, timer, 0);

glutMouseFunc(mouse);

glutMotionFunc(motion);

glutKeyboardFunc(Keyboard);

glutMainLoop();

}

下面就是旋轉的效果

week 14

今天要講 TRT 關節旋轉的程式碼

首先來一個正常的茶壺做準備囉~

然後先做一個 timer 讓他自動旋轉，並且把旋轉軸心設在手把上

最後正式把TRT完成拉~ 自己畫的註解不好看
就借一下小葉老師的圖片拉~~~
畫得很不錯呢!

最後附上自己的程式碼囉!!!

Week10

那個禮拜，因為有事情所以沒到學校，所以在家自己看著做做看囉~

原來這次是 OpenCV 的下載安裝教學和貼圖的應用囉!!!

這下面就是安裝過程的詳細作法和設定囉!!!

至於後面的貼圖使用的部分由於我有上11周的課

更詳盡的內容就在那裏了!!!

這裡就簡單放幾張完成的畫面

Week 08

NeHe Lesson32.zip 解壓縮，玩射擊遊戲。

Light Material(打光)、Texture(貼圖)的範例程式

接下來就是要試著做上面那個射擊遊戲囉~~~~

當滑鼠按下時發出槍聲並印出Shot!

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

{

if(state== GLUT_DOWN){

PlaySound("Shot.wav",NULL,SND_ASYNC);

printf("Shot!\n");

}

任意按一鍵跳出全螢幕

void keyboard(unsigned char key,int x,int y)

{

exit(0);

}

設立浮點數作為物體座標

float potX=-1 ,potY=0;

修改display 畫出茶壺並且讓他依照座標跑

void display()

{

potX+=0.01;

if(potX>1.1) potX=-1.1;

glClearColor(0.5,0.5,0.5,0);

glClear(GL_COLOR_BUFFER_BIT);

glPushMatrix();

glTranslated(potX,potY,0);

glutSolidTeapot(0.05);

glPopMatrix();

glFlush();

}

在main() 裡面增加

glutIdleFunc(display);

在系統閒暇時就執行display的函數

如果點擊位置接近則有音效跑出

float mouseX=2*x/1280.0 -1, mouseY=2*y/1024 -1;

if( fabs(mouseX - potX)< 0.1 && fabs(mouseY - potY)<0.1){

PlaySound("glass.wav",NULL, SND_ASYNC);

printf("You got it!");

}

#include <GL/glut.h>

#include <mmsystem.h>

#include <stdio.h>

#include <math.h>

float potX=-1 ,potY=0;

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

{

if(state== GLUT_DOWN){

PlaySound("Shot.wav",NULL,SND_ASYNC);

printf("Shot!\n");

}

float mouseX=2*x/1280.0 -1, mouseY=2*y/1024 -1;

if( fabs(mouseX - potX)< 0.1 && fabs(mouseY - potY)<0.1){

PlaySound("glass.wav",NULL, SND_ASYNC);

printf("You got it!");

}

void keyboard(unsigned char key,int x,int y)

{

exit(0);

}

void display()

{

potX+=0.01;

if(potX>1.1) potX=-1.1;

glClearColor(0.5,0.5,0.5,0);

glClear(GL_COLOR_BUFFER_BIT);

glPushMatrix();

glTranslated(potX,potY,0);

glutSolidTeapot(0.05);

glPopMatrix();

glFlush();

}

int main(int argc,char **argv)

{

glutInit(&argc,argv);

glutCreateWindow("01160536");

glutFullScreen();

glutDisplayFunc(display);

glutIdleFunc(display);

glutKeyboardFunc(keyboard);

glutMouseFunc(mouse);

glutMainLoop();

}

用基本的 printf 顯示出按下鍵盤確定有效果

加入標頭檔使音效可以使用
在按下keyboard 觸發音效及印出字串

#include <GL/glut.h>

#include <stdio.h>

#include <mmsystem.h>

void display()

{

glutSolidTeapot(0.3);

glFinish();

}

void keyboard(unsigned char key,int x,int y)

{

if(key=='a')

{

PlaySound("rocket.wav",NULL,SND_ASYNC);

printf("小心!!! 火箭來囉~~~\n");

}

int main(int argc,char** argv)

{

glutInit(&argc,argv);

glutCreateWindow("hello");

glutDisplayFunc(display);

glutKeyboardFunc(keyboard);

glutMainLoop();

}
