內插公式

1.用Excel嘗試內插公式看是否可以成功 x*新+(1-x)*舊

2.把角度改成內插角度

3.內插公式的函式加入

4.Timer函式準備好

寫檔案

#include <stdio.h>

FILE* fout =NULL; ///檔案指標

. 在keyborad()中

if(key=='s' || key=='S')
{
if(fout==NULL)
{
fout=fopen("file.txt","w+");
printf("現在我產生一個file.txt的檔案在目錄裡面哦\n");
}
fprintf(fout, "%.3f %.3f %.3f %.3f %.3f %.3f %.3f %.3f\n", angle[0],angle[1],angle[2],angle[3],angle[4],angle[5],angle[6],angle[7]);///寫檔案的第5行
printf("現在我把一些數字印到檔案裡面%.3f %.3f %.3f %.3f %.3f %.3f %.3f %.3f\n",angle[0],angle[1],angle[2],angle[3],angle[4],angle[5],angle[6],angle[7]);
}
if(key=='r' || key=='R')
{
if(fin==NULL){///read讀檔案的第2行
fin=fopen("file.txt", "r");///read讀檔案的第3行
}
fscanf(fin, "%f %f %f %f %f %f %f %f", &angle[0], &angle[1], &angle[2], &angle[3], &angle[4], &angle[5], &angle[6], &angle[7]);///read讀檔案的第4行
glutPostRedisplay();///read讀檔案後, 要重畫畫面
}
}

5.成功執行
