week15課程主題
1.播聲音跟播mp3
2.播放動畫、內插
3.機器人擺動做跟跳舞
音源相關素材網站:https://sound-effects.bbcrewind.co.uk/
上課所使用的音檔:https://sound-effects.bbcrewind.co.uk/search
(找裡面的07042111.wav)
設定Settings - compiler - Linker settings - add - winmm(聲音相關)
寫完會發出聲音
///week15-1 PlaySound.cpp
///#include <mmsystem.h>上週教
#include<windows.h>///另一種寫法
int main()
{ ///先放不存在的檔 上週教SND_ASYNC
PlaySound("badbadbad.wav",NULL,SND_SYNC);
}///Compile成功,但是link失敗!!
///.c .cpp = compile => .o = link => .exe
注意音檔是WAV檔，且音檔要與程式碼同一個資料夾
///week15-2 SND_SYNC要等待同步 VS.
///SND_ASYNC不用等待、不同步
#include <windows.h>
#include <stdio.h>///printf()
int main()
{
printf("現在在PlaySound()前\n");
PlaySound("07042111.wav",NULL,SND_ASYNC);
printf("現在在PlaySiund()後\n");
int N;
scanf("%d",&N);///等你輸入數字
}
差別
1. SND_SYNC 改為 SND_ASYNC
2. SND_ASYNC 的不同在於不用等待，播放後就不理了
3. 增加的 scanf 在等待你輸入數字(卡住不要結束聲音)，輸入後即結束程式(結束聲音)
----------------------------------------------------------------------------------------------------------------
要在準備一份mp3檔，並下載老師提供的CMP3_MCI.h檔
注意都需要跟程式碼放在一起才能夠執行
///week15-3 希望能夠播放mp3
///MP3檔案小 vs. WAV檔案大 PlaySound()
///有壓縮/難 原始資料
#include "CMP3_MCI.h"///下載放在同目錄
#include <stdio.h>
CMP3_MCI mp3;
int main()
{
mp3.Load("07042111.mp3");
mp3.Play();
printf("現在正在播放羊的聲音");
int N;///找一個人卡住，不要結束
scanf("%d",&N);(scanf 為卡住程式，使其不要結束)
}
以上的程式碼都是.cpp檔，不需要開GLUT專案(開專案也沒關係，還是能夠執行)
建立一個GLUT新專案Week15 angles TRT again
接續上週week14的week14 TRT Angle Write And Read專案程式
keyboard()裡if(key)
///week15_anagles_TRT_angle

步驟:
1.接下來新增一個專案week15_homework_gundam_parts
2.複製剛才Week15 angles TRT again的程式貼上
3.下載老師的鋼彈模型(Teams第11周myGundam)
3.1將myGundam解壓縮
3.2點開解壓縮過後的myGundam資料夾，找到data
3.3將data複製到專案week15_homework_gundam_parts資料夾裡
4.設定glm
4.1下載老師的sorce(Teams第11周上課用)，並將裡面的glm.c改成glm.cpp
4.2複製glm.cpp、glm.h並放到專案week15_homework_gundam_parts資料夾裡面
4.3在左邊專案工具列，對專案week15_homework_gundam_parts的標題點擊右鍵
=> Add files =>點選glm.cpp
5.修改工作目錄
5.1到專案week15_homework_gundam_parts裡面找到week15_homework_gundam_parts.cbp
=>點擊右鍵，選擇開啟Notepad++
5.2找到<Option working_dir=""D:/school/大下課程/電腦圖學/電腦圖學必備檔案/freegut/bin" />
(一開始都會預設在freeglut資料夾那邊，所以要修改目錄)
修改成=><Option working_dir="." />
但要注意的是，就算儲存過了一次，也有可能沒有修改好
因此我們需要在重開一次，檢查檔案是否有確實修改到
6.將freeglut資料夾/bin裡面的freeglut.dll複製到專案week15_homework_gundam_parts資料夾裡面
修改程式碼，將白色鋼彈顯示出來

設定一個 myReadOne函式來讀取模型檔，再設定一個新的display()來畫出分割過的部位(因此舊的display才需要改名)
