本週課程內容:播放聲音、TRT存檔撥放
播放聲音
步驟:開啟新.cpp檔-->進setting>compiler>link-->add"winmm"
-->PlaySound("07072005.wav", NULL,SND_SYNC);只能撥放wav檔(如下圖)-->播放MP3格式(如下圖)

筆記~圖學 Week15
程式PlaySound
0.CodeBlocks內設定：Setting-Compiler
(1) Linker settings，Add，winmm
1.聲音同步、不同步（PlaySound()只能播wav檔，不能播mp3檔）
2.聲音同步
3.聲音不同步
4.聲音mp3
5.調好動作才存檔
´◔౪◔）Morning Star
Week15 電腦圖學
# 播放聲音 #
Step0. New Empty File => week15-1_PlaySound.cpp
Step1. PlaySound("檔名.wav", NULL, SND_SYNC)
async=不等待/不同步 sync=等待/同步
Q1. 打完code之後跑不出來？？？ undifined reference to `PlaySoundA@12'
A1. Setting - Compiler Setting, Linker 加入 winmm
注意呦!!! PlaySound只能用 wav檔
Step3. 了解更多PlaySound() 參數
3-0. New File => week15-2_SND_SYMC SND_ASYNC.cpp
3-1. 不等待就是可以更快執行到下一行
!!! 想要播放 mp3檔 !!!
1. 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()
# 接續上週3D進度 #
Step0. Open GLUT專案 => week15_angle_TRT_again
Step1. Copy 上週code
因為要一次一次調，一次只能調一個關節
要讓他可以多個關節一起所以要做
Step2. keyboard() motion() 加 myWrite()
# 擺動作 #
1. 需要 3D Model 被切塊過的(才可以動動喔)
2. 需要TRT 才能轉動
3. keyboard() 切換關節
4. mouse motion() 轉關節
Step0. 開新專案
Step1. 工作執行目錄 working_dir 改成上週教的更改 (用notepa++開cbp)
Step2. 把freeglut.dall複製到檔案同目錄中
Step3. 要把 glm.h glm.cpp 及 gundom放進去檔案裡跟目錄
Step4. 在codeblocks裡的左邊工作列，按右鍵add glm.cpp
Step5. 開始寫code
# Homewook 4 可擺 Pose的機器人 #
week15電腦圖學
4z week15
1.開CodeBlocks->建立新的Empty File week15-1_PlaySound.cpp 並在在settings->compiler加入winmm
#include <windows.h>
#include <stdio.h>
int main()
{
printf("PlaySound()\n");
PlaySound("07042111.wav",NULL,SND_SYNC);
printf("PlaySound()之後\n");
}
2..開 CodeBlocks/empty file-->week15_SND_SNTC_ASNYC.cpp
直接播
#include <windows.h>
#include <stdio.h>
int main()
{
PlaySound("do.wav",NULL,SND_SYNC);///ASYNC不等待
PlaySound("re.wav",NULL,SND_SYNC);
PlaySound("mi.wav",NULL,SND_SYNC);
}
等待
#include <windows.h>
#include <stdio.h>
int main()
{
PlaySound("07042111.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);
}
}
3.開 CodeBlocks/empty file-->week15_MP3.cpp並到moodle 下載CMP3_MCI.h
#include <stdio.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
nt main()
{
mp3.Load("009160986.mp3");
mp3.Play();
printf("隨便等你輸入數字,程式就卡住了 : ");
int N;///為了程式不要結束
scanf("%d",&N);
}
4.myWrite()會寫一行，myRead()會讀一行,然後要在keyboard()裡面新增動作s，當按下s後會儲存當前手臂的位置
#include <GL/glut.h>
#include <stdio.h>
float angle[20],oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite(){
if(fout == NULL) fout = fopen("file.txt", "w+");
for(int i=0 ; i<20 ; i++){
printf(" %.1f ", angle[i]);
fprintf(fout, " %.1f ",angle[i]);
}
printf("\n");
fprintf(fout,"\n");
}
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();
}
void mouse(int Button, int state, int x, int y){
oldX= x;
}
void keyboard (unsigned char key,int x,int y){
if(key=='s') myWrite(); ///調好動作再存檔
if(key=='r') myread();
if(key=='0') angleID=0;
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
}
void motion(int x,int y){
angle[angleID] += (x-oldX);
///myWrite();
oldX = x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle[2],0,0,1);
glTranslatef(0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle[3],0,0,1);
glTranslatef(0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit( &argc, argv );
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week15-1_angles_TRT_again");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
讓機器人擺動作
1.需要3D Model (glm.h,glm.cpp .obj....)
2.需要切割模型分別讀入
3.使用TRT程式轉動分割後的模型keboard() 切換關節， mouse motion()用滑鼠轉動關節
4.建立一個新GLUT專案 week15_hw_gundam_parts
5.用Notepad++將工作目錄的路徑改成 "."
week15
播放聲音不同方法:
聲音 PlaySound()
設定Setting-Compiler-Linker settings-Add-winmm
存成.wav檔 ( PlaySound()函示只能撥放.wav檔喔!!! )
#include <stdio.h>
#include <windows.h>
int main(){
printf("PlaySound()之前\n");///SYNC 等待&同步
PlaySound("07043055.wav", NULL , SND_SYNC);///只能播.wav檔
///檔名出錯(檔案不存在),播放錯誤的聲音
printf("PlaySound()之後\n");
}
不等待&不同步 等待&同步
(馬上回應;適合互動) (適合背景音樂)
2.播聲音 .mp3
.mp3 v.s. .wav
有壓縮 原始;無壓縮
開新檔案File-New-Empty file>
#include <stdio.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;///宣告變數
int main(){
mp3.Load("bbc_crowds--ch_07043055.mp3");
mp3.Play();
printf("隨便等你輸入數字:");
int N;///為了卡住程式不要直接結束
scanf("%d",&N);
}
圖學week15
今天一開始我們先學播聲音
因為沒有音檔，所以一開始應該會播錯誤訊息的音效
然而可能程式會錯誤無法播放
就必須在compilier>linker裡設定winmm
然後是MP3檔 要先去moodle下載CMP3_MCI.h
才能播放
#include <stdio.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
int main()
{
mp3.Load("07042111.mp3");
mp3.Play();
printf("隨便輸入數字程式就卡住了: ");
int N;
scanf("%d",&N);
}
然後我們把上週教的動畫程式碼複製過來
因為上週教的程式會動得很慢，所以我們要改善它
把myWrite()註解掉，在keyboard裡新增save的程式
#include <GL/glut.h>
#include <stdio.h>
float angle[20],oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite()
{
if(fout == NULL)fout=fopen("file.txt","w+");
for (int i=0;i<20;i++)
{
printf("%.1f ",angle[i]);
fprintf(fout,"%.1f ",angle[i]);
}
printf("\n");
fprintf(fout,"\n");
}
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();
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='s')myWrite();
if(key=='r')myRead();
if(key=='0')angleID=0;
if(key=='1')angleID=1;
if(key=='2')angleID=2;
if(key=='3')angleID=3;
}
void mouse(int button,int state,int x,int y )
{
oldX=x;
}
void motion(int x,int y)
{
angle[angleID] += (x-oldX);
///myWrite();
oldX=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1.0,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle[2],0,0,1);
glTranslatef(+0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle[3],0,0,1);
glTranslatef(+0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1.0,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week15");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
VERY BEAUTIFUL、VERY POWERFUL
一
1.先開一個codeblocks檔案，存檔打出下列格式
///
#include <windows.h>
#include <stdio.h>
int main()
{
printf("PlaySound()之前\n");
///檔案不存在，會有很小聲的錯誤聲
PlaySound("07071064.wav", NULL, SND_SYNC);
printf("PlaySound()之後\n");
}
///
因為沒有設定，視窗跳不出來
把winmm打進compiler的liker setting
然後上去這網站搜尋想要的音檔下載
https://sound-effects.bbcrewind.co.uk/search
把音檔跟codeblocks檔案放在同一個資料夾
這樣就能順利執行了!
2.
開啟一個新檔案，命名為"week15-2_SND_SYNC_SND_ASYNC"
打出下列程式碼
///
#include <windows.h>
#include <stdio.h>
int main()
{
PlaySound("do.wav", NULL, SND_SYNC);///ASYNC不等待
PlaySound("re.wav", NULL, SND_SYNC);///ASYNC不等待
PlaySound("mi.wav", NULL, SND_SYNC);///ASYNC不等待
}
///
把DO、RE、MI 3個檔案放進去就可以順利執行了
把上一個作業音檔載過來，再把程式碼改成以下
///
#include <windows.h>
#include <stdio.h>
int main()
{
PlaySound("07071064.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);///ASYNC不等待
if(N==2) PlaySound("re.wav", NULL, SND_ASYNC);///ASYNC不等待
if(N==3) PlaySound("mi.wav", NULL, SND_ASYNC);///ASYNC不等待
}
}
///
ASYNC不用等待，可直接跳過一開始的聲音
這樣就可以輸入數字漸打出DO、RE、MI的聲音
