week16

(1)

1-1.alpha內插公式 : alpha : `0.0~1.0`
       `angle = alpha * 新 + ( 1 - alpha ) * 舊`
      ex.
      - alpha : 0 => 舊
      - alpha : 0.5 => 半新半舊
      - alpha : 1 => 新
1-2.開glut ，用上週TRT_again程式改

(1)

1-1.開 CodeBlocks/empty file-->week15_PlaySound.cpp

#include <windows.h>
#include <stdio.h>
int main()
{
    printf("PlaySound()\n");
    PlaySound("07042111.wav",NULL,SND_SYNC);

}

⃟   如果錯誤會有錯誤音效

1-2.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){

⃤   按s可以存動作

⃤   找txt複製動作可以做很多次r


(3)HW

3-1.開新專案week15_HW
3-2.用notepad++改目錄-->"."
3-3.把freeglut/bin/freeglut.dll複製到cbp資料夾

2-3.

    (1)用notepad++ 開 cbp檔 ---> 把working_dir 裡的路徑改成"."
    (2)把freeglut裡的freeglut.dll複製到專案中

這樣txt就會放到程式專案目錄了

(3)

3-1.開新專案week14_timer
3-2.
#include <GL/glut.h>

void timer(int t){
    printf("起床,現在時間 : %d\n",t);
}
void display(){
}
int main(int argc,char**argv)

1-3.刪註解 -->加顏色跟手臂 ，改軸心 ，加角度，手掛回身體
#include <GL/glut.h>
float angle=45;
void display()

        ///glRotatef(angle,0,0,1);
        ///glTranslatef(-0.3,-0.4,0);把軸心放中心
        glColor3f(1,0,0);///紅
        glRectf(0.3,0.5,0.7,0.3);
    glPopMatrix();
    glutSwapBuffers();
}

    glutMainLoop();
}

1-4.按滑鼠可以旋轉手臂
