Week16

*視角
gluLookAt(eyex,eyey,eyez,objx,objy,objz,upx,upy,upz);
參數：觀看者x,觀看者y,觀看者z,物體x,物體y,物體z,角度向量x,角度向量y角度向量z

*運鏡
if(key==' ') {eyex-=0.02,eyey-=0.02;}
按空白鍵改變視角

*旋轉運鏡
void timerRotateShow(int t)
{
glutTimerFunc(30,timerRotateShow,t+1);
eyex=cos(t/100.0*3.1415);
eyez=sin(t/100.0*3.1415);
eyey-=0.005;
glutPostRedisplay();
}

*背景顏色
if(t%10==0)glClearColor((rand()%255)/255.0,(rand()%255)/255.0,(rand()%255)/255.0,(rand()%255)/255.0);

*放大縮小

Week14

*播放wav檔
#include <windows.h>
#include <mmsystem.h>

int main()
{
    PlaySound("glass.wav",NULL,SND_SYNC);
}

SND_SYNC表示同步

SND_ASYNC表示不同步

*播放MP3檔

先載入CMP3_MCI.h

並放入song.mp3到資料夾中

scanf用來當暫停

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include "CMP3_MCI.h"

CMP3_MCI mymp3;

int main()

{

int a;

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

mymp3.Load("song.mp3");

mymp3.Play();

scanf("%d",&a);

}
