程式碼：
float eyex=0.3,eyey=0.2,eyez=0.4,objx=0,objy=0,objz=0,upx=0,upy=1,upz=0;
void display()
{
glEnable(GL_DEPTH_TEST);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
gluLookAt(eyex,eyey,eyez,objx,objy,objz,upx,upy,upz);
glRotatef(angleX, 0,1,0);
glPushMatrix();//右肩
glTranslatef(0.25, 0.3, 0);
glutSolidSphere(0.1, 30, 30);
glPushMatrix();//右臂
glRotatef(angle2, 0, 0, 1);
glTranslatef(0.2, 0, 0);
glScalef(0.5, 0.1, 0.1);

2. 使用空白鍵做運鏡

程式碼：
float angleX =0, angle2 = 0, angle3 = 0;
float eyex=0.3,eyey=0.2,eyez=0.4,objx=0,objy=0,objz=0,upx=0,upy=1,upz=0; *將宣告往前提*
void keyboard(unsigned char key, int x, int y)
{
if(key=='1') angleX+=5;//全身的轉動
if(key=='2') angleX-=5;//全身的轉動
if(key=='3') angle2+=5;//手的轉動
if(key=='4') angle2-=5;//手的轉動
if(key=='5') angle3+=5;//腳的轉動
if(key=='6') angle3-=5;//腳的轉動
if(key=='0') //控制運鏡轉動
{
eyex-=0.02;
eyey-=0.02;
}
glutPostRedisplay();
}

3. 解決破圖

程式碼：

void myLight()

{

const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

glEnable(GL_LIGHT0);

glEnable(GL_NORMALIZE);

glEnable(GL_COLOR_MATERIAL);

glEnable(GL_LIGHTING);

glLightfv(GL_LIGHT0, GL_POSITION, light_position);

}

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

{

if(key=='1') angleX+=5;//全身的轉動

if(key=='2') angleX-=5;//全身的轉動

if(key=='3') angle2+=5;//手的轉動

if(key=='4') angle2-=5;//手的轉動

if(key=='5') angle3+=5;//腳的轉動

if(key=='6') angle3-=5;//腳的轉動

if(key=='0')

{

eyex-=0.02;

eyey-=0.02;

}

else if(key=='a')

{

glMatrixMode(GL_PROJECTION);

glLoadIdentity();

glOrtho(-2,2,-2,2,-10,10);

glMatrixMode(GL_MODELVIEW);

}

glutPostRedisplay();

}

4. 邊旋轉邊放大，背景變色

1.內插法

程式碼：
#include<GL/glut.h>
float a=0;
float angle=0;
float angleOld=0;
float angleNew=90;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void keyboard(unsigned char key,int x,int y)
{
if(key=='z')
{
a+=0.1;
angle=angleOld*(1-a)+angleNew*a;
}
glutPostRedisplay();
}
int main()
{
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week15");
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutMainLoop();
}

2.改用矩陣方式儲存

修改程式部分；

#include<GL/glut.h>

float a=0;

float angle[20]={0,90,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

float angleOld[20]={0,90,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

float angleNew[20]={90,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

void display()

{

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glRotatef(angle[0],0,0,1);

glutSolidTeapot(0.3);

glPopMatrix();

glPushMatrix();

glTranslatef(0.5,0,0);

glRotatef(angle[1],0,0,1);

glutSolidTeapot(0.3);

glPopMatrix();

glutSwapBuffers();

}

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

{

if(key=='z')

{

a+=0.1;

angle[0]=angleOld[0]*(1-a)+angleNew[0]*a;

angle[1]=angleOld[1]*(1-a)+angleNew[1]*a;

angle[2]=angleOld[2]*(1-a)+angleNew[2]*a;

angle[3]=angleOld[3]*(1-a)+angleNew[3]*a;

angle[4]=angleOld[4]*(1-a)+angleNew[4]*a;

angle[5]=angleOld[5]*(1-a)+angleNew[5]*a;

angle[6]=angleOld[6]*(1-a)+angleNew[6]*a;

angle[7]=angleOld[7]*(1-a)+angleNew[7]*a;

angle[8]=angleOld[8]*(1-a)+angleNew[8]*a;

}

glutPostRedisplay();

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week15");

glutKeyboardFunc(keyboard);

glutDisplayFunc(display);

glutMainLoop();

}

3.自動轉動

程式碼：

#include<GL/glut.h>

float a=0;

float angleNew[20]={90,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

void display()

{

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glTranslatef(angle[3],angle[4],angle[5]);

glPushMatrix();

glRotatef(angle[0],0,0,1);

glutSolidTeapot(0.3);

glPopMatrix();

glPushMatrix();

glTranslatef(0.5,0,0);

glRotatef(angle[1],0,0,1);

glutSolidTeapot(0.3);

glPopMatrix();

glutSwapBuffers();

}

void readNext()

{

a+=0.1;

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

{

angle[i]=angleOld[i]*(1-a)+angleNew[i]*a;

}

void timer(int t)

{

glutTimerFunc(10,timer,0);

readNext();

glutPostRedisplay();

}

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

{

if(key=='z')//手動轉動

{

readNext();

}

else if(key=='p') //自動轉動

{

glutTimerFunc(0,timer,0);

}

glutPostRedisplay();

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week15");

glutKeyboardFunc(keyboard);

glutDisplayFunc(display);

glutMainLoop();

}

4.加入滑鼠控制、存檔、讀檔

程式碼：

#include<stdio.h>

#include<GL/glut.h>

float a=0;

glPopMatrix();

glPushMatrix();

glTranslatef(0.5,0,0);

glRotatef(angle[1],0,0,1);

glutSolidTeapot(0.3);

glPopMatrix();

glutSwapBuffers();

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

{

oldX=x; oldY=y;

}

void motion(int x, int y)

{

angle[angleID] += x-oldX; oldX=x;

glutPostRedisplay();

}

void timer(int t)

{

glutTimerFunc(10,timer,0);

readNext();

glutPostRedisplay();

}

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

{

if(key=='0') angleID=0;

fprintf(fout,"%f ",angle[i]);

}

printf("\n");

fprintf(fout,"\n");

}

if(key=='z')

{

readNext();

}

else if(key=='p')

{

glutTimerFunc(0,timer,0);

}

glutPostRedisplay();

}

int main()

WEEK14

1. 播放音樂 (歡呼聲)

程式碼：

#include <windows.h>

#include <mmsystem.h>

int main()

{

PlaySound("cheer.wav",NULL,SND_SYNC);

}

2. 開新專案加上音樂播放

新增程式碼：

#include <windows.h>

#include <mmsystem.h>

int main()

{

PlaySound("cheer.wav",NULL,SND_ASYNC); //SND_SYNC→要等同步 SND_ASYNC→不等同步

}

*要將音樂檔複製到資料夾中!!

3. 將音樂以MP3檔方式播放

新增程式碼：

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

int main()

{

myMP3.Load("Hero.mp3");

myMP3.Play();

}

1. 複習上週：

程式碼：

#include <GL/glut.h>

#include <opencv/highgui.h>

#include <opencv/cv.h>

float angleX =0, angle0=0, angle1=0, angle2=0, angle3=0;

GLuint id[4];//技巧2: 使用陣列, 讓變數變簡單 simple

IplImage * img[4];

char filename[4][100]={"imgBody.png", "imgHand0.png", "imgLeg0.png", "imgLeg1.png"};

void myTexture()

{

glEnable(GL_TEXTURE_2D);

for(int i=0; i<4; i++){//技巧3: 迴圈, 可以讓程式碼, 做重覆的事可以很爽清爽

img[i] = cvLoadImage( filename[i] );

cvCvtColor(img[i], img[i], CV_BGR2RGB);

glGenTextures(1, &id[i]);

glBindTexture(GL_TEXTURE_2D, id[i]);//head

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_LINEAR);

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_LINEAR);

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img[i]->width, img[i]->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img[i]->imageData);

}

void myRect()//技巧1: 重覆的程式碼, 用函式拉出來, 就不用一直copy啦

{//函式就是黑盒子幫你做事情!

glPushMatrix();

glScalef(0.2, 0.5, 0.5);

glBegin(GL_POLYGON);

glTexCoord2f(0,0); glVertex3f(-0.5, 0.5,0);

glTexCoord2f(0,1); glVertex3f(-0.5,-0.5,0);

glTexCoord2f(1,1); glVertex3f( 0.5,-0.5,0);

glTexCoord2f(1,0); glVertex3f( 0.5, 0.5,0);

glEnd();

glPopMatrix();

}

void display()

{

glEnable(GL_DEPTH_TEST);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glBindTexture(GL_TEXTURE_2D, id[0]);

myRect();//body//技巧1: 用函式, 哥就是帥!

glPushMatrix();//left hand

glTranslatef(-0.1, 0.15, 0);

glRotatef(angleX, 0,0,1);

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[1]);

myRect();//技巧1: 用函式, 哥就是帥!

glPopMatrix();

glPushMatrix();//left leg

glTranslatef( -0.05, -0.25, 0);

glRotatef(180-angleX, 0,0,1);

glTranslatef(0, 0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[2]);

myRect();

glPushMatrix();//left foot

glTranslatef( 0, 0.25, 0);

glRotatef(30, 0,0,1);

glBindTexture(GL_TEXTURE_2D, id[3]);

myRect();

glPopMatrix();

glPushMatrix();//right leg

glTranslatef( 0.05, -0.25, 0);

glTranslatef(0, 0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[2]);

myRect();

glPopMatrix();

glutSwapBuffers();

}

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

{

if(key=='1') angleX+=5;

if(key=='2') angleX-=5;

glutPostRedisplay();//請電腦重新畫一次畫面

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("week11");

glutDisplayFunc(display);

glutKeyboardFunc(keyboard);

myTexture();

glutMainLoop();

}

2. 增加左右手臂與腳

變更程式碼：

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glBindTexture(GL_TEXTURE_2D, id[0]);

myRect();//body//技巧1: 用函式, 哥就是帥!

glPushMatrix();//left hand

glTranslatef(-0.1, 0.15, 0);

glRotatef(angleX, 0,0,1);

glTranslatef(0, -0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[1]);

myRect();//技巧1: 用函式, 哥就是帥!

glPushMatrix();

glTranslatef(0,-0.25,0);

glRotatef(angleX,0,0,1);

glTranslatef(0,-0.25,0);

myRect();

glPopMatrix();

glPushMatrix();//right hand

glTranslatef(0.1, 0.15, 0);

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[1]);

myRect();//技巧1: 用函式, 哥就是帥!

glPushMatrix();

glTranslatef(0,-0.25,0);

glRotatef(-angleX,0,0,1);

glTranslatef(0,-0.25,0);

myRect();

glPopMatrix();

glPushMatrix();//left leg

glTranslatef( -0.05, -0.25, 0);

glRotatef(180-angleX, 0,0,1);

glTranslatef(0, 0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[2]);

myRect();

glPushMatrix() ; //left foot

glTranslatef( 0, 0.25, 0);

glRotatef(angleX, 0,0,1);

glTranslatef(0, 0.15, 0);

glBindTexture(GL_TEXTURE_2D, id[3]);

myRect();

glPopMatrix();

glPushMatrix();//right leg

glTranslatef( 0.05, -0.25, 0);

glRotatef(-(180-angleX), 0,0,1);

glTranslatef(0, 0.25, 0);

glBindTexture(GL_TEXTURE_2D, id[2]);
