01160306_呂季樺_第十六周

第16週目標: 粒子系統(particles)、運鏡、換色, etc (看情況加上複習)
第17週期末作品展示
1. gluLookAt( eyeX, eyeY, eyeZ, objX, objY, objZ, upX, upY, upZ);
1.1. 裝 glut DevPak, 把你的期末作品開起來, 試著用 gluLookAt()來改改看攝影機的位子, 像是 45度俯視看你的臉

Week15

Week17!!!!! Final Project Demo

=====

內插(interpolation)

動作A ------> 動作B

a=0 .................a=1

你的動作(angle[...])

angle[0] = angleOld[0]*(1-a) + angleNew[0]*a; //內插公式

口訣: 交叉相乘

ex.

a=0, angle[0] 是 angleOld[0]

a=0.1, angleOld[0]*0.9 + angleNew[0]*0.1

a=0.5, angleOld[0]*0.5 + angleNew[0]*0.5

a=0.9,

a=1, anlge[0] 是 angleNew[0]

01160306_呂季樺_第十四周

目標:

聲音: (4) 音效, (5) 音樂

動作: (1) 讀檔播放, (2) 自動播放 (使用timer計時器鬧鐘會定期響), (3) 內插變得較 smooth

1. 播放聲音 WAV音效 (未壓縮) (使用 PlaySound()函式)

2. 播放音樂 MP3檔 (使用 CMP3_MCI.h, 它是運用 mciSendString()的技巧, 但是我們只要會 Load及Play即可)

以下分別做介紹:

1. 播放聲音 WAV音效 (未壓縮) (使用 PlaySound()函式)

1.1. 重點是分成前面 #include <Windows.h> 及 #include <mmsystem.h> 之後才能使用PlaySound()

1.2. PlaySound() 的用法是 PlaySound("檔名.wav", NULL, SND_ASYNC);

1.3. 比較一下 SND_ASYNC 及 SND_SYNC 的差別 (ASYNC是不等同步,直接各做各的) (SYNC是要等 PlaySound()整個播完, 才能接下去再做)

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

int main()

{

PlaySound("檔名.wav", NULL, SND_ASYNC);//這行以上才是重點

printf("Please input a number:\n");

int n; scanf("%d", &n);//這行只是要卡住的, 別隨便用啊!
