淺談二維和三維影象資料
再將其輸出為檔案的程式碼如下，都是比較簡單的讀寫呼叫，由此同時可以看出，無論是2維還是3維影象，使用一維陣列的方式存資料，對於IO來說是十分方便。
void OutPutVolume(const char* fileName,unsigned char* pointer,int width,int height,int depth) { int length=width*height*depth; FILE *const nfile = fopen(fileName,"wb"); fwrite(pointer,sizeof(unsigned char),length,nfile); fclose(nfile); }
前段時間需要找各種三維影象來做實驗，發現這個www.volvis.org及其不穩定，時不時就是伺服器關閉了，這樣會導致需要資料的時候比較麻煩，所以這裡乾脆把一些常用的資料下來到部落格園貼著，以防不時之需。
