1. 延續上禮拜的程式

    -原本只有做左邊，加上了右邊

    -原本自動轉，換成用滑鼠轉動

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;

int angleID=0;

int oldX=0;

void timer(int t)///timer不用動，改keyboard動

{

    ///程式搬家，改用mouse motion來做動作

}

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

{

    oldX = x;///當mouse按下去時記下位置

}

void motion(int x, int y)///當我motion動

{

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

    oldX = x;///再更新位置

    glutPostRedisplay();

}

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

{

    if(key=='0') angleID=0;

    if(key=='1') angleID=1;

    if(key=='2') angleID=2;

    if(key=='3') angleID=3;

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glutSolidTeapot(0.3);///身體

        glPushMatrix();///左邊

            glTranslatef(-0.3,0,0);

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

            glTranslatef(-0.3,0,0);

            glutSolidTeapot(0.2);

            glPushMatrix();

                glTranslatef(-0.3,0,0);

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

                glTranslatef(-0.3,0,0);

                glutSolidTeapot(0.2);

            glPopMatrix();

        glPopMatrix();

        glPushMatrix();///右邊

            glTranslatef(0.3,0,0);

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

            glTranslatef(0.3,0,0);

            glutSolidTeapot(0.2);

            glPushMatrix();

                glTranslatef(0.3,0,0);

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

                glTranslatef(0.3,0,0);

                glutSolidTeapot(0.2);

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutKeyboardFunc(keyboard);

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

2. 印出資料

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;

int angleID=0;

int oldX=0;

FILE * fout = NULL;

void timer(int t)

{

    

}

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

{

    oldX = x;

}

void motion(int x, int y)

{

    angle[angleID] += x - oldX;

    oldX = x;

    glutPostRedisplay();

    if(fout==NULL) fout=fopen("angle.txt", "w+");

    for(int i=0; i<20; i++) fprintf(fout, "%.1f ", angle[i]);

    fprintf(fout, "\n");///印到.txt檔案裡

    for(int i=0; i<20; i++) printf("%.1f ", angle[i]);

    printf("\n");///印到畫面

}

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

{

    if(key=='0') angleID=0;

    if(key=='1') angleID=1;

    if(key=='2') angleID=2;

    if(key=='3') angleID=3;

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glutSolidTeapot(0.3);

        glPushMatrix();

            glTranslatef(-0.3,0,0);

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

            glTranslatef(-0.3,0,0);

            glutSolidTeapot(0.2);

            glPushMatrix();

                glTranslatef(-0.3,0,0);

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

                glTranslatef(-0.3,0,0);

                glutSolidTeapot(0.2);

            glPopMatrix();

        glPopMatrix();

        glPushMatrix();

            glTranslatef(0.3,0,0);

            glRotatef(angle[2], 0,0,1);

            glTranslatef(0.3,0,0);

            glutSolidTeapot(0.2);

            glPushMatrix();

                glTranslatef(0.3,0,0);

                glRotatef(angle[3], 0,0,1);

                glTranslatef(0.3,0,0);

                glutSolidTeapot(0.2);

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutKeyboardFunc(keyboard);

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

*因為我沒有改到工作位置，所以在freeglut\bin裡*

3. 撥放動畫

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;

int angleID=0;

int oldX=0;

FILE * fout = NULL;

FILE * fin = NULL;///檔案指標

void timer(int t)

{

    glutTimerFunc(30, timer, t+1);///播放動畫

    if(fin==NULL) fin=fopen("angle.txt", "r");

    for(int i=0; i<20; i++) fscanf(fin, "%f", &angle[i]);

    glutPostRedisplay();///重畫畫面

}

4. 先存動作，再讀動作

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;

int angleID=0;

int oldX=0;

FILE * fout = NULL;

FILE * fin = NULL;

void timer(int t)

{

//    glutTimerFunc(30, timer, t+1);///播放動畫

//    if(fin==NULL) fin=fopen("angle.txt", "r");

//    for(int i=0; i<20; i++) fscanf(fin, "%f", &angle[i]);

//    glutPostRedisplay();///重畫畫面

}

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

{

    oldX = x;

}

void motion(int x, int y)

{

    angle[angleID] += x - oldX;

    oldX = x;

    glutPostRedisplay();

//    if(fout==NULL) fout=fopen("angle.txt", "w+");

//    for(int i=0; i<20; i++) fprintf(fout, "%.1f ", angle[i]);

//    fprintf(fout, "\n");///印到.txt檔案裡

//    for(int i=0; i<20; i++) printf("%.1f ", angle[i]);

//    printf("\n");///印到畫面

}

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

{

    if(key=='0') angleID=0;

    if(key=='1') angleID=1;

    if(key=='2') angleID=2;

    if(key=='3') angleID=3;

    if(key=='s')///save

    {

        if(fout==NULL) fout=fopen("angle.txt", "w+");

        for(int i=0; i<20; i++) fprintf(fout, "%.1f ", angle[i]);

        fprintf(fout, "\n");

        for(int i=0; i<20; i++) printf("%.1f ", angle[i]);

        printf("\n");

    }

    if(key=='r')///read

    {

        if(fin==NULL) fin=fopen("angle.txt", "r");

        for(int i=0; i<20; i++) fscanf(fin, "%f", &angle[i]);

        glutPostRedisplay();

    }

    if(key=='p')///play

    {

    }

}

按s之後存下位置數值，關掉黑窗自動存檔angle.txt

複製數值(動作位置)

按r讀取數值

5. 讓他連續動作

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;///angle[i]畫的角度，內插angleold[i] anglenew[i]

float angleold[20]={}, anglenew[20]={};///新舊角度內插

int angleID=0;

int oldX=0;

FILE * fout = NULL;

FILE * fin = NULL;

void timer(int t)

{

    glutTimerFunc(30, timer, t+1);

    if(t%10==0)///每10frame，就讀一筆新資料

    {

        for(int i=0; i<20; i++) angleold[i] = anglenew[i];

        ///讀新資料之前要先把資料備份

        if(fin==NULL) fin=fopen("angle.txt", "r");

        for(int i=0; i<20; i++) fscanf(fin, "%f", &anglenew[i]);

    }   ///再讀新資料

    float alpha = (t%10)/10.0;

    for(int i=0; i<20; i++)

    {

        angle[i] = alpha*anglenew[i] + (1-alpha)*angleold[i];

    }

    glutPostRedisplay();

}

 fprintf()

printf()執行檔案印出資料

fprintf()把資料建檔

#include <stdio.h>///printf(),fprintf()

int main(int argc, char**argv)

{

    FILE * fout = NULL;///檔案的指標 fout output用

    fout = fopen("檔名.txt", "w+");///開檔，使用w+模式

    printf("Hello World\n");

    fprintf(fout,"Hello World\n");

}

2. 把執行工作目錄換成現在的目錄，執行生成檔案

3. scanf()>>>fscanf() 配合fopen() r模式 read

#include <stdio.h>///printf(), fprintf(), fscanf(), fopen()

int main(int argc, char**argv)

{

    ///FILE * fout = NULL;///檔案的指標 fout output用

    ///fout = fopen("檔名.txt", "w+");///開檔，使用w+模式

    ///printf("Hello World\n");

    ///fprintf(fout,"Hello World\n");

    FILE * fin = NULL;///fin input用

    fin = fopen("檔名.txt", "r");

    ///scanf("%d", &n); 配int n;

    ///scanf("%f", &f); float f;

    ///scanf("%c", &c); char c;

    ///scanf("%s", line); char line[100];

    char line[100];

    fscanf(fin, "%s", line);

    printf("你讀到了字串: %s\n", line);

    fscanf(fin, "%s", line);

    printf("你讀到了字串: %s\n", line);

}

機器人

1. 

#include <stdio.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glutSolidTeapot(0.3);///身體

        glutSolidTeapot(0.3);///左手臂(重疊)

        glutSolidTeapot(0.3);///右手臂(重疊)

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15");

    glutDisplayFunc(display);

    glutMainLoop();

}

2. 旋轉

#include <stdio.h>

#include <GL/glut.h>

float angle=0, diff=2;

void timer(int t)

{

    glutTimerFunc(30, timer, t+1);

    angle += diff;

    if(angle>90) diff=-2;

    if(angle<0) diff=+2;

    glutPostRedisplay();///現在用這個比較好，以前用display()重畫

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        //glutSolidTeapot(0.3);

        glPushMatrix();

            glTranslatef(-0.3,0,0);///(3)掛在正確的地方

            glRotatef(angle, 0,0,1);///(2)旋轉

            glTranslatef(-0.4,0,0);///(1)把關節旋轉中心放到畫面中心

            glutSolidTeapot(0.3);

            glPushMatrix();

                //glutSolidTeapot(0.3);

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15");

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

3. 現在把另外兩節也顯示出來

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glutSolidTeapot(0.3);///身體

        glPushMatrix();

            glTranslatef(-0.3,0,0);

            glRotatef(angle, 0,0,1);

            glTranslatef(-0.4,0,0);

            glutSolidTeapot(0.3);///左手臂(沒有重疊)

            glPushMatrix();

                glTranslatef(-0.3,0,0);

                glRotatef(angle, 0,0,1);

                glTranslatef(-0.4,0,0);

                glutSolidTeapot(0.3);

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

4. 改變旋轉物件(關節)

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;///本來只有1個角度，現在有很多個，初始為0

int angleID=0;///現在要改幾個角度

void timer(int t)

{

    glutTimerFunc(30, timer, t+1);

    angle[angleID] += diff;

    if(angle[angleID]>90) diff=-2;

    if(angle[angleID]<0) diff=+2;

    glutPostRedisplay();///現在用這個比較好，以前用display()重畫

}

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

{

    if(key=='1') angleID=1;

    if(key=='0') angleID=0;

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glutSolidTeapot(0.3);///身體

        glPushMatrix();

            glTranslatef(-0.3,0,0);

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

            glTranslatef(-0.4,0,0);

            glutSolidTeapot(0.3);///左手臂(沒有重疊)

            glPushMatrix();

                glTranslatef(-0.3,0,0);

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

                glTranslatef(-0.4,0,0);

                glutSolidTeapot(0.3);

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15");

    glutKeyboardFunc(keyboard);///整合很多關節，去改變angleID

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

張淳雅_Week14

 Timer與動畫

1. 

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidSphere(0.3,30,30);///半徑,縱切,橫切

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );

    glutCreateWindow(" Week14 timer ");

    glutDisplayFunc(display);

    glutMainLoop();

}

2. 等三秒換背景色

#include <GL/glut.h> void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glutSolidSphere(0.3,30,30); glutSwapBuffers(); }

void timer(int t) { glClearColor(1,0,0,0);///背景色紅色 display();///重畫畫面 }

int main(int argc, char** argv) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH ); glutCreateWindow(" Week14 timer "); glutDisplayFunc(display); glutTimerFunc(3000,timer,0); glutMainLoop(); }

3. 等三秒，背景變色方塊旋轉

#include <GL/glut.h> float angle=0; void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glRotatef(angle,0,0,1); glutSolidCube(0.3);///換方塊才看得到旋轉 glPopMatrix(); glutSwapBuffers(); } void timer(int t)     { glutTimerFunc(30,timer,t+1); glClearColor(1,0,0,0); angle++; display(); } int main(int argc, char** argv) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH ); glutCreateWindow(" Week14 timer "); glutDisplayFunc(display); glutTimerFunc(3000,timer,0); glutMainLoop(); }

4. 向左轉90度換向右轉90度，重複動作

#include <GL/glut.h> float angle=0; void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glRotatef(angle,0,0,1); glutSolidCube(0.3); glPopMatrix(); glutSwapBuffers(); } int diff=2; void timer(int t) { glutTimerFunc(20,timer,t+1); glClearColor(1,0,0,0); if(angle>90)diff=-2; if(angle<0)diff=+2; angle+=diff; display(); } int main(int argc, char** argv) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH ); glutCreateWindow("week14"); glutDisplayFunc(display); glutTimerFunc(3000,timer,0); glutMainLoop(); }

5. 加入一個紅色長方(一樣三秒後變紅色背景)

#include <GL/glut.h> float angle=0; void drawArm1() { glPushMatrix(); glScalef(1,0.5,0.5);///長方形 glColor3f(1,0,0);///紅色 glutSolidCube(0.2); glPopMatrix(); } void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glColor3f(1,1,1); glutSolidCube(0.4); glPushMatrix(); ///glTranslatef(); ///glRotatef(angle,0,0,1); glTranslatef(-0.1,0,0); drawArm1(); glPopMatrix(); glPopMatrix(); glutSwapBuffers(); } int diff=2; void timer(int t) { glutTimerFunc(20,timer,t+1); glClearColor(1,0,0,0); if(angle>90)diff=-2; if(angle<0)diff=+2; angle+=diff; display(); } int main(int argc, char** argv) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH ); glutCreateWindow("week14"); glutDisplayFunc(display); glutTimerFunc(3000,timer,0); glutMainLoop(); }

6. 把方塊掛角上並旋轉(三秒後變紅色背景，綠色方塊向左轉90度換向右轉90度，重複動作)

#include <GL/glut.h> float angle=0; void drawArm1() { glPushMatrix(); glScalef(1,0.5,0.5); glColor3f(0,1,0);///換綠色方便看 glutSolidCube(0.2); glPopMatrix(); } void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glColor3f(1,1,1); glutSolidCube(0.4); glPushMatrix(); glTranslatef(-0.2,0.2,0);///掛上肩膀 glRotatef(angle,0,0,1); glTranslatef(-0.1,0,0); drawArm1(); glPopMatrix(); glPopMatrix(); glutSwapBuffers(); } int diff=2; void timer(int t) { glutTimerFunc(20,timer,t+1); glClearColor(1,0,0,0); if(angle>90)diff=-2; if(angle<0)diff=+2; angle+=diff; display(); } int main(int argc, char** argv) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH ); glutCreateWindow("week14"); glutDisplayFunc(display); glutTimerFunc(3000,timer,0); glutMainLoop(); }

鋼彈!!!

1. 用3D Exploration將gundam還沒切開.zip裡面的Gundam.obj重新存檔成.cpp (Sample APP)，稱成gundam_cut.cpp、gundam_cut_0.bmp

2. 開一個新的OpenGL，把原本的main.c刪掉，add files...gundam_cut.cpp

3. 因為系統找不到GL_BGR_EXT、GL_BGRA_EXT，所以最上面加入兩行

    #define GL_BGR_EXT 0x80E0

    #define GL_BGRA_EXT 0x80E1

4. 把

    (LPLOGPALETTE) lpPalette = (LPLOGPALETTE)HeapAlloc (hHeap, 0,

    sizeof (LOGPALETTE) + (nColors * sizeof (PALETTEENTRY)));

取消(//)

5. 執行

6. 取消選轉縮放，讓他站著轉

glMatrixMode (GL_MODELVIEW);

glLoadIdentity ();

glTranslatef (0.0f, 0.0f, -8.0f);

//glRotatef (30.0f, 1.0f, 0.0f, 0.0f);

//glRotatef ((GLfloat) nAngle, 0.0f, 1.0f, 0.0f);

//glRotatef ((GLfloat) nAngle2, 1.0f, 0.0f, 0.0f);

//glScalef (nSize+2.5f,nSize+2.5f,nSize+2.5f);

glRotatef (nAngle,0,1,0);///旋轉

glScalef(3,3,3);

 3D模型

1. 把source.zip的glm.c改成glm.cpp

2. glm.h、glm.cpp、transformation.c複製到專案資料夾裡

3. 將transformation.c的內容複製到main.cpp裡

4. 把glm.cpp加入專案

5. 將data.zip的所有檔案複製到freeglut\bin

6. 執行

7. 試著開啟模組

#include "glm.h"

GLMmodel * pmodel= NULL;

void

drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/porsche.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

8. 打光

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

}

鋼彈!!!

1. 把gundam還沒切開.zip裡面的Gundam.mtl跟Gundam.obj複製到freeglut\bin\data裡

2. 把程式碼的檔案名稱改掉

#include "glm.h"

GLMmodel * pmodel= NULL;

void

drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/Gundam.obj");///檔名

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClearColor(1,1,1,1);///加入背景色

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(180, 0,1,0);///轉180度

        drawmodel();

    glPopMatrix();

    glutSwapBuffers();

}

3. 貼圖

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

GLuint id1, id2;

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename);

    cvCvtColor(img,img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, &id);

    glBindTexture(GL_TEXTURE_2D, id);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

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

    return id;

}

#include "glm.h"

GLMmodel * pmodel= NULL;

void

drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/Gundam.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_TEXTURE);

}

 播放音檔

1. 播放一個音檔

#include <windows.h>

int main()

{

    PlaySound("shot.wav", NULL,SND_SYNC);///音檔放在freeglut\bin裡

}

2. 播放多個音檔

#include <windows.h>

int main()

{///播放聲音("檔名.wav", 空指標, 等待同步);

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

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

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

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

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

}

3. 因為音檔時間太長，改成輸入指令並按Enter執行音檔

#include <windows.h>

#include <stdio.h>

int main()

{///播放聲音("檔名.wav", 空指標, 不等待同步);

    while (1){

        char c=getchar();

        if (c=='1') PlaySound("do.wav", NULL,SND_ASYNC);

        if (c=='2') PlaySound("re.wav", NULL,SND_ASYNC);

        if (c=='3') PlaySound("mi.wav", NULL,SND_ASYNC);

        if (c=='4') PlaySound("fa.wav", NULL,SND_ASYNC);

        if (c=='5') PlaySound("so.wav", NULL,SND_ASYNC);

    }

}

    4. 因為要在按Enter太麻煩，所以改成直接按指令發聲音

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

5. 邊播放音樂邊下指令撥放其他音樂

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"///.h檔放在這個專案的資料夾裡

CMP3_MCI mp3;///宣告一個MP3變數

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    mp3.Load("music.mp3");///檔案放在freeglut\bin裡

    mp3.Play();///播放

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

6. 讓左右中鍵按下並發出聲音

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

CMP3_MCI shot1,shot2,shot3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

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

{

    if(state==GLUT_DOWN&&button==GLUT_LEFT_BUTTON) shot1.Play();

    if(state==GLUT_DOWN&&button==GLUT_MIDDLE_BUTTON) shot2.Play();

    if(state==GLUT_DOWN&&button==GLUT_RIGHT_BUTTON) shot3.Play();

}

int main(int argc, char**argv)

{

    shot1.Load("1.wav"); shot2.Load("2.mav"); shot3.Load("3.wav");

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}
