電腦圖學筆記week15
step01-1
PlaySound() 更詳細解說
0.New Empty File,存檔成week15-1_PlaySound.cpp
1.#include<mmsystem.h>上週教的
2.#include<windows.h>這週教的
3.PlaySound( " 檔名.wav" , NULL,SND_ASYNC );//上週
4.PlaySound( "檔名.wav" , NULL,SND_SYNC );//這週
5.Setting-Complier Setting,Linker 加入 winmm
6.下載個wav檔放進程式碼目錄
#include <windows.h>
#include <stdio.h>
int main()
{
printf("PlaySound()之前\n");
PlaySound("badbad.wav",NULL,SND_SYNC);
printf("PlaySound()之後\n");
}
可播放音樂

0.New Empty File,存成week15-2_SND_SYNC_SND_ASYNC
#include <windows.h>
#include <stdio.h>
int main()
{
PlaySound("badbad.wav",NULL,SND_ASYNC);///ASYNC不等待
while(1){
printf("請輸入數字: ");
int N;
scanf("%d",&N);
if(N==1) PlaySound("do.wav",NULL,SND_ASYNC);
if(N==2) PlaySound("re.wav",NULL,SND_ASYNC);
if(N==3) PlaySound("mi.wav",NULL,SND_ASYNC);
}
}///最後一行,就沒了
ASYNC互動效果比較好
step02-1
WAV (大/原始)vs. MP3(小/有壓縮)
PlaySound只能用WAV檔
0. New Empty File ,week15-3_mp3.cpp
1.在moodle下載 CMP3_MCI.h
2.程式碼 #include "CMP3_MCI.h"
3.宣告 CMP3_MCI mp3;
4.mp3.Load("檔名.mp3");
5.mp3.Play();
#include <stdio.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
int main()
{
mp3.Load("badbad.mp3");
mp3.Play();
printf("隨便等你輸入數字,程式就卡住囉: ");
int N;
scanf("%d",&N);
}
step02-2
0.開新GLUT專案 week15_angles_TRT_again
1.複製上週程式，試跑2.不像動畫 動作不自然
3.myWrite()會寫一行 myRead()會讀一行
4.不能把myWrite()放motion()
5.關節動作調好再存檔
6.所以擺完動作後再按s存檔
///week15修改自week14_angles_fprintf
#include <GL/glut.h>
#include <stdio.h>
float angle[20],oldX=0;
int angleID=0;
FILE * fout=NULL, * fin = NULL;
void myWrite()
{///每呼叫一次myWrite
if(fout == NULL)fout=fopen("file.txt","w+");
for(int i = 0;i<20;i++)
{
printf("%.1f ",angle[i]);///小黑印出來
fprintf(fout,"%.1f ",angle[i]);///檔案印出來
}///這裡老師沒有fclose
printf("\n");///小黑印出跳行
fprintf(fout,"\n");///檔案跳行
}
void myRead()
{
if(fout!=NULL){fclose(fout); fout=NULL;}
if(fin==NULL) fin=fopen("file.txt","r");
for(int i=0;i<20;i++)
{
fscanf(fin,"%f",&angle[i]);
}
glutPostRedisplay();///重劃畫面
}
void keyboard(unsigned char key,int x,int y)

if(key=='s') myWrite();///調好動作才save存檔
if(key=='r') myRead();

}
step03-1
機器人擺動
1.開新GLUT專案 week15_hw_gundam_parts
2.工作執行目錄 working.dir 不太好, 要改到現在程式的目錄
3.用Notepad++編輯 cbp檔的路徑，working dir 路徑改成小數點，把freeglut.dll放進目錄
