week15 蔣

 WEEK15

week15-0

到https://jsyeh.org/3dcg10/網頁，下載win32和data，把他們解壓縮，將data放入window，開啟Transformation.exe檔

下載git ，把上禮拜的檔案雲端下載下來

先下載git，把之前的檔案雲端下載下來，建立一個project專案

打上程式碼

float eyeX = 0, eyeY = 0;

void motion(int x, int y){

    eyeX = 3*(x-320)/320.0;

    eyeY = 3*(240-y)/240.0;

    glLoadIdentity();

    gluLookAt(eyeX, eyeY, 3, 0, 0, -6, 0, 1, 0);

    glutPostRedisplay();

}

底下還有

    glutMotionFunc(motion);

新增程式碼    glOrtho(-ar*3, ar*3, -1.0*3, 1.0*3, 2.0, 100.0);

註解掉glFrustum(-ar, ar, -1.0, 1.0, 2.0, 100.0);，會有一個對稱圖案

加上gluPerspective(60, ar, 0.01, 1000);

加上新的程式

#include <GL/glut.h>

void display()

{

    glClear(  GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glutSolidTeapot(0.3);

    glutSwapBuffers();

}

void motion(int x, int y){

    glLoadIdentity();

    float eyeX = (x-150)/150.0, eyeY = (150-y)/150.0;

    gluLookAt(eyeX,eyeY,1, 0,0,0, 0,1,0);

    glutPostRedisplay();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week15");

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

 WEEK13

week13-1

從Git指令下載整個倉庫，用CodeBlocks開啟Final_Project.cbp專案檔，以後不用再裝freeglut了

week13-2

利用MAYA把上課範例的Al.obj裁切成很多部位，要放入Final_Project裡面，創一個叫model的資料夾把剛剛裁切的東西放進去，再把model資料夾放入Final_Project裡，再把week10裡的glm.cpp及glm.h複製貼上到Final_Project裡，用CodeBlocks開啟Final_Project.cbp，修改程式。如下:

///之後都用同一個程式來進行Final_project

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

week11-2 keyboard_PlaySound

老師先傳一個聲音檔給我們，桌面上會有do-re-mi的檔案，再來複製貼上第一個程式後修改程式，按1 2 3 就會有do-re-mi的聲音

#include <windows.h>

#include <GL/glut.h>

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

{

    if(key=='1') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav",NULL,SND_ASYNC);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

week11-3 PlaySound.cpp

開啟一個CPP檔，用Hello World播放do-re-mi，到Settings-Compiler裡設定Linker settings打上winmm

打上新的程式，執行後可以聽到do-re-mi的聲音後跑出Hello World。

#include <windows.h>

#include <stdio.h>

int main()

{

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_SYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav",NULL,SND_SYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav",NULL,SND_SYNC);

    printf("Hello World\n");

}

week11-4_CMP3_MCI_Load_Play

老師先傳MP3檔給我們，開一個的glut檔，裡面程式不用刪，然後丟進week11-4目錄裡，更改137行的程式，如下。

include "CMP3_MCI.h"///雙引號表示是同個目錄裡的

CMP3_MCI myMP3;

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

{

    char filename[]="C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

    myMP3.Load(filename);

    myMP3.Play();

    glutInit(&argc, argv);

    glutInitWindowSize(640,480);

    glutInitWindowPosition(10,10);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

執行後就會有suzume的音樂。

把freeglut-bin裡的freeglut.dll跟老師給的資料夾裡的suzume.mp3複製貼上到week11-4的目錄裡，

更改程式讓程式變簡單，再到codeblocks裡的project-Properties打開然後照圖片更改成"."。

再更改一些程式，如下

#include "CMP3_MCI.h"///雙引號表示是同個目錄裡的

CMP3_MCI myMP3;

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

{

    ///char filename[]="C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

    ///myMP3.Load(filename);

    myMP3.Load("suzume.mp3");

    myMP3.Play();

    glutInit(&argc, argv);

    glutInitWindowSize(640,480);

    glutInitWindowPosition(10,10);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

執行後一樣可以聽到音樂。這修改是讓東西都放在同個工作目錄下，比較好找。

先把 opencv 跟 freeglut用好

開啟新的freeglut檔案然後命名

把Computer Graphics (jsyeh.org)的source下載解壓縮然後把glm.c跟glm.h拉進桌面的week10-1檔案裡

再把老師給的鋼蛋三張圖片放進桌面的freeglut/bin裡,把Diffuse圖片用小畫家打開然後垂直翻轉再打上程式,執行就可以跑出鋼蛋模型了

到桌面week10-1目錄裡把week10-1 glm gundamCBD檔用Notepad++開啟然後更改東西,再把freeglut/bin裡的四個檔案複製貼上到week10-1裡,執行目錄就會更改了,成功的話鋼蛋就可以執行出來

week08 蔣

 WEEK08

week08-0

到https://jsyeh.org/3dcg10/網頁,下載source,data,windows全部解壓縮,data放入window,

了解3D模型是如何產生的

v 對應 vertex頂點

vt對應貼圖座標

vn對應vertex normal法向量

f對應 面facet

去may匯出obj檔,取名叫F-16

從桌面把兩個檔案丟入data裡

打開Transformation換F-16,就有自己的模型了
