• week08貼圖程式先貼上

程式碼:

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

GLuint id1, id2; ///TODO:增加2個 貼圖ID

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename);

    cvCvtColor(img,img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, &id); /// 產生Generate 貼圖ID

    glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖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;

    glBegin(GL_POLYGON);

        glTexCoord2f(0,1);glVertex2f(-1,-1);

        glTexCoord2f(1,1);glVertex2f(+1,-1);

        glTexCoord2f(1,0);glVertex2f(+1,+1);

    id1 = myTexture("diffuse.jpg");///改成模型.jpg

    id2 = myTexture("bg.jpg");

    glEnable(GL_DEPTH_TEST);

    glutMainLoop();

}

執行結果:

2.步驟

• 更改工作目錄cbp

• 增加檔案置專案夾
• 檔名更改glm.c ----> glm.cpp

• 增加程式碼:
• 更改為GLM_TEXTURE

程式碼:

#include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("Gundam.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_TEXTURE);///有改

}

• 利用小畫家把圖片垂直翻轉

• 整體旋轉

程式碼:

glPushMatrix();

        glRotatef(angle, 0,1,0); 

        drawmodel();

    glPopMatrix();

• 如果讓他轉動，他會跑到布幕後，所以需要改程式碼

程式碼:

         glTexCoord2f(0,1);glVertex3f(-1,-1,+0.9);///後移

        glTexCoord2f(1,1);glVertex3f(+1,-1,+0.9);

        glTexCoord2f(1,0);glVertex3f(+1,+1,+0.9);

        glTexCoord2f(0,0);glVertex3f(-1,+1,+0.9);

• 加入支解的模型ex:GLMmodel*hand1=NULL;

程式碼:

GLMmodel*arm1=NULL;///切開的小模型

GLMmodel*arm2=NULL;

GLMmodel*hand1=NULL;

GLMmodel*hand2=NULL;

chjyuʕ •ᴥ•ʔ week12 3D模型-1

 1. 3D exploration(模型切割)

下載安裝:3D exploration(放在moodle3D設計)

*要先解壓縮gumdan.zip

1-1加入codeblocks

• codeblocks開啟OPENGL
• 把原本的main.c remove
• 把桌面上的gundam.cpp&貼紙放同目錄專案裡
• 打開codeblocks-add files

於第一行增加程式碼:

#define GL_BGRA_EXT 0x80E1

#define GL_BGR_EXT 0x80E0

//註解Palette的兩行 ///調色盤

執行結果:

1-2更變模型轉動模式與大小

• //註解原本程式裡頭的rotate&scale

增加程式碼:

glRotatef( nAngle, 0, 1, 0);///朝y軸轉動

glScalef(3, 3, 3);///模型大小

執行結果:

2.MAYA匯出模型關節

• 匯入為切開的gundam.obj
• 選取面-圈選整隻左手

• 匯出OBJ檔

• 完成

2-1 glut

• 專案檔的cpd開啟notepad++
• 更改執行資料夾"C:\Users\Administrator\Desktop\freeglut\bin" ------> "."

• 把C:\Users\Administrator\Desktop\freeglut\bin裡.dll ctrlC到專案檔裡

執行結果:

chjyuʕ •ᴥ•ʔ week11 3D模型

 1.基礎設定

(1)下載Moodle 3個ZIP檔

(2)windows.zip,data.zip解壓縮-data放入windows裡

(3)source.zip解壓縮-glm.c,glm.h,translation.c放入現在的執行專案

• glm.c ---> glm.cpp
• transformation--->Notepad++開啟，複製程式碼。貼在main.cpp裡

(4)增加新檔(3D模型一個檔，程式碼一個檔)相互連接

• 執行:有閃退=成功!!!

(5)把data放入 freeglut/bin裡

執行結果:

成功囉!!!

chjyuʕ •ᴥ•ʔ week10 播放聲音

 1.播放聲音

(1)(還沒有shot的執行目錄，所以只有"燈愣"的聲音)

程式碼:

#include<windows.h>

int main()

{                    ///執行目錄 ///空指標  ///要等同步

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

}

(2)找音源檔(一定要wav檔)

youtube 轉MP3:https://www.y2mate.com/zh-tw/youtube-mp3/tQ0yjYUFKAE

MP3轉Wav:https://www.aconvert.com/tw/audio/mp3-to-wav/

(3)讓多個音源連接著一起撥放(不用同步,要敲Enter)

程式碼:

#include<windows.h>

#include <stdio.h>

int main()

{

    while(1){

        char c = getchar();

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

        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)圖片後加聲音(不用敲Enter)

程式碼:

#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)///按數字鍵

{

    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_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10 playsound");

    glutDisplayFunc(display);

    glutKeyboardFunc( keyboard);

    glutMainLoop();

}

(5)用MP3放入背景/同時

程式碼:

#include <windows.h>

#include <GL/glut.h>

#include"CMP3_MCI.h" ///.h檔要放在專案目錄下

CMP3_MCI mp3;///宣告一個變數(MP3的變數)

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);

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

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

}

int main(int argc, char *argv[])

{

    mp3.Load("music.mp3");///檔案放執行目錄....\freeglut\bin

    mp3.Play(); ///播放

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10 playsound");

    glutDisplayFunc(display);

    glutKeyboardFunc( keyboard);

    glutMainLoop();

}

(6)除了背景音樂還加上了滑鼠案鍵有聲音

程式碼:

#include <windows.h>

#include <GL/glut.h>

#include"CMP3_MCI.h"

CMP3_MCI mp3;

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);

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

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

}

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

{

    if(state==GLUT_DOWN) PlaySound("shot.wav", NULL, SND_ASYNC);

}///按下滑鼠有聲音

int main(int argc, char *argv[])

{

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10 playsound");

    glutDisplayFunc(display);

    glutKeyboardFunc( keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

(7)讓滑鼠多個聲音共存

程式碼:

#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);

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

    if(key=='5') PlaySound("so.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_LEFT_BUTTON) shot2.Play();

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

}

int main(int argc, char *argv[])

{

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

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10 playsound");

    glutDisplayFunc(display);

    glutKeyboardFunc( keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

(8)把音樂放到同一個執行專案
