1.交叉相乘喔！內插用鍵盤讓茶壺轉動

#include <GL/glut.h>

float a=0;//a is the alpha weight內插的比重 

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);//用現在的角度angle來轉動 

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;//內插公式 

}

glutPostRedisplay();//重劃一次畫面

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week15");

glutKeyboardFunc(keyboard);

glutDisplayFunc(display);

glutMainLoop();

}

2.把浮點數變成陣列。

#include <GL/glut.h>

float a=0;//a is the alpha weight內插的比重 

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);//用現在的角度angle來轉動 

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;//內插公式 

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;

angle[9]=angleOld[9]*(1-a)+angleNew[9]*a;

}

glutPostRedisplay();//重劃一次畫面

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week15");

glutKeyboardFunc(keyboard);

glutDisplayFunc(display);

glutMainLoop();

}

3.簡化程式&加上Timer讓程式自動播放！

#include <GL/glut.h>

float a=0;//a is the alpha weight內插的比重 

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();

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

glPushMatrix();

glRotatef(angle[0], 0, 0, 1);//用現在的角度angle來轉動 

glutSolidTeapot(0.3);

glPopMatrix();

glPushMatrix();

glTranslatef(0.5, 0, 0);

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

glutSolidTeapot(0.3);

glPopMatrix();

glPopMatrix();

glutSwapBuffers();       

}

void readNext()

{

a+=0.1;

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

{ angle[i]=angleOld[i]*(1-a)+angleNew[i]*a;//內插公式 

}

}

void timer(int t)

{

glutTimerFunc(10, timer, 0);//幾ms後開始, 0 ms後開始播放(一按按鍵就立即播放)

readNext();

glutPostRedisplay(); 

}

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

{

if(key=='x')

{

readNext(); //按x就一下一下轉

}

else if(key=='y')

{

glutTimerFunc(0, timer, 0);//按下y就一次自己轉

}

glutPostRedisplay();

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week15");

glutKeyboardFunc(keyboard);

glutDisplayFunc(display);

glutMainLoop();

}

１４週

~~以下動作都要裝OPENCV和glut的紙箱~~

來播wav格式的音檔喔！

Step.1-下載wav檔案，跟專案放在同一個資料夾。

Step.2-加入程式碼：

#include <windows.h>

#include <mmsystem.h>// Multiple Media

int main()

{

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

}

Step.3-開小黑囉

若要開啟小黑視窗，在專案按右鍵專案選項內選Win32Console。

發現問題！！小黑出不來！！怎摸辦？

記得在程式碼多按一個空白鍵代表有編輯過小黑才出的來!

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

現在來播MP3檔案！！！！

Step.1-下載MP3檔案，跟專案放在同一個資料夾

Step.2-臉書下載CMP3_MCI.h檔案，跟專案放在同一個資料夾

Step.3-加上MP3檔案專屬的程式碼

標頭：

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

main函式：

myMP3.Load("song.mp3");

myMP3.Play();

發現問題！！閃退了！！怎摸辦？

加一段廢話程式碼就好了 ˊ 3 ˋ~

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

現在來讓聲音跟影片同步播喔！！！！

wav檔案的處理方式

Step.1-開新專案

Step.2-加入播放wav的程式碼

p.s記得要把音檔放進專案資料夾！！！

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

MP3檔案的處理方式

Step.1&2同wav檔

播放MP3的程式碼

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

Step.2-準備好圖檔

Step.3-把圖檔放在專案資料夾：

Step.4-到opencv資料夾裡面把所有dill檔案都複製到專案資料夾

Step.5-加入重要的咒語在參數中

-lcv -lcxcore -lhighgui 

注意咒語後要有空格！！！
