2022電腦圖學二乙: Zfish week15

一:

1-1-1:

Settings->Compiler...->linker settings->增加咒語"winmm"

1-1-2:

///#inlcude <mmsystem.h>///上週教

#include <windows.h>///另一種寫法，結果一樣

int main()

{

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

}

///Compile成功,但link失敗

/// .c .cpp = compilr -> .o = link -> .exe

///#inlcude <mmsystem.h>///上週教
#include <windows.h>///另一種寫法，結果一樣
int main()
{
///PlaySound("badbadbad.wav",NULL ,SND_SYNC);
PlaySound("07042111.wav",NULL ,SND_SYNC);
}
///Compile成功,但link失敗
/// .c .cpp = compilr -> .o = link -> .exe

1-2:

/// SND_SYNC(要等待同步)
/// vs.
/// SND_ASYNC(不用等待、不同步))
#include <windows.h>
#include <stdio.h>
int main()
{
printf("現在在PlaySound()前\n");
PlaySound("07042111.wav",NULL ,SND_ASYNC);
printf("現在在PlaySound()後\n");
int N;
scanf("%d",&N);
}

1-3:

///mp3(檔案小、有壓縮) vs. wav(檔案大、原始資料)

#include "CMP3_MCI.h"

#include <stdio.h>

CMP3_MCI mp3;

int main()

{

mp3.Load("07042111.mp3");

mp3.Play();

printf("現在正在播放\n");

int N;///卡住，不要結束

scanf("%d",&N);

}

二:使用week14_TRT_angle_write_and_read

2-1:

#include <GL/glut.h>
#include <stdio.h>///為了printf,fopen,fclose...
float angle[20], oldX=0;
int angleID=0;///0:第0個關節, 1:第1個關節...
FILE * fout=NULL, * fin=NULL;
void myWrite(){
if(fout==NULL) fout=fopen("file.txt","w+");
for(int i=0; i<20; i++){
printf( "%.2f", angle[i]);
fprintf(fout, "%.2f ", angle[i]);
}
printf("\n");
fprintf(fout,"\n");
}
void myRead(){
if(fout!=NULL){
fclose(fout);///關掉還在讀的檔案
fout=NULL;
}
if(fin==NULL) fin=fopen("file.txt","r");
for(int i=0; i<20; i++){
fscanf(fin, "%f", &angle[i]);
}
glutPostRedisplay();///重畫畫面
}
void keyboard(unsigned char key, int x, int y){///鍵盤數字鍵決定旋轉部位
if(key=='r') myRead();
if(key=='s') myWrite();
if(key=='0') angleID=0;///預設0
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
if(key=='r'){
myRead();
}
}
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();///重畫畫面
}
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glColor3f(1, 1, 1);
glRectf(0.3, 0.5, -0.3, -0.2);///身體瘦身(對比1)
glPushMatrix();///右半邊
glTranslatef(0.3, 0.5, 0);
glRotatef(angle[0], 0, 0, 1);///旋轉
glTranslatef(-0.3, -0.4, 0);///旋轉中心放正中心
glColor3f(1, 0, 0);
glRectf(0.3, 0.5, 0.8, 0.3);///右上手臂
glPushMatrix();
glTranslatef(0.8, 0.4, 0);///把下手肘掛在關節上
glRotatef(angle[1], 0, 0, 1);///旋轉
glTranslatef(-0.8, -0.4, 0);///把下手肘的旋轉中心放正中心
glColor3f(0, 1, 0);
glRectf(0.8, 0.5, 1.1, 0.3);///右下手肘
glPopMatrix();
glPopMatrix();
glPushMatrix();///左半邊
glTranslatef(-0.3, 0.5, 0);
glRotatef(angle[2], 0, 0, 1);///旋轉
glTranslatef(+0.3, -0.4, 0);///旋轉中心放正中心
glColor3f(1, 0, 0);
glRectf(-0.3, 0.5, -0.8, 0.3);///左上手臂
glPushMatrix();

glTranslatef(+0.8, -0.4, 0);///把下手肘的旋轉中心放正中心
glColor3f(0, 1, 0);
glRectf(-0.8, 0.5, -1.1, 0.3);///左下手肘
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH );
//glutInitWindowSize(600, 600);
glutCreateWindow("week15_angles_TRT_again");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
