Week12_Summer

今日目標：

1、主題：鍵盤
2、主題：聲音、音樂
3、複習：階層T-R-T骨架
4、作業：能操控的機器人

 01 先去http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

下載"win32"、"data"、"glut32.dll" 三個檔案並解壓縮放入對應資料夾中

 02 https://www.transmissionzero.co.uk/software/freeglut-devel/

下載MinGW的 "Download freeglut 3.0.0 for MinGW"

 03 至 CodeBlock 開一個新的專案 Console Application

 04 能播放音樂的程式，記得要在專案按右鍵 \ Bulid options \ Linker settings 中

Add Linker library 加入 winmm 即可執行程式

 05 試試看把 PlauSound 函式 放入 GLUT 專案裡面

先 run 出音樂才會 run 出小黑窗

 06 在全部撥放完之後，可以手動按鍵盤'1'、'2'、'3'、'4'、'5'

發出'do'、're'、'mi'、'fa'、'so'的聲音

 07 最後做出不用WAV檔也可以順利撥出音樂的程式

 程式碼： 

/*

 * GLUT Shapes Demo

 *

 * Written by Nigel Stewart November 2003

 *

 * This program is test harness for the sphere, cone

 * and torus shapes in GLUT.

 *

 * Spinning wireframe and smooth shaded shapes are

 * displayed until the ESC or q key is pressed.  The

 * number of geometry stacks and slices can be adjusted

 * using the + and - keys.
