function LandmineShower()
% 該函數用來對雷場圖像進行三維顯示

% 讀取圖象數據到矩陣
[A, map] = imread('input.bmp');

% 得到圖象信息
info = imfinfo('input.bmp');
w = info.Width;
h = info.Height;

% 創建與圖象大小相對應的網格
[x,y] = meshgrid(1:w,1:h);
z = x - y + y - x;
i = 1;
j = 1;

% 用圖象灰度值填充高度值
while (i - 1) * w + j <= w * h
    z(i,j) = A(i,j);
    j = j + 1;
    if j > w
        j = 1;
        i = i + 1;
    end

% 繪制三維圖象

% 繪制表面
