本人在學習完製作雙波源干涉現象的的二維Contour Plots影象之後，發現 plotly 還有3D 影象製作，也就是3D Surface Plots，這個更能展示雙波源干涉現象的結果，果然學之。中間有些地方要說明一下，3D Surface Plots圖表預設的底部是正方形，所以我採用了100*100的干涉圖，然後加上一層透明的圖示，讓影象壓扁，不然圖示的上下限就是波動位置，看起來非常不雅觀。

下面分享程式碼和結果：

下面是 python部分的程式碼：

#!/usr/bin/python
# coding=utf-8

import plotly.plotly

z = []
with open("/Users/Vicky/Documents/workspace/fission/long/intervene.log") as apidata:
    for i in apidata:
        data = i.split("\n")[0].split(",")
        z.append(data)
matrix = [[20 for zij in zi] for zi in z]#為了讓立體圖壓扁
plotly.offline.plot([
     dict(
            z=z,
            type="surface"
    ),
    dict(
            z=matrix,
            showscale=False,
            opacity=0.01,#透明度
            type="surface"
    )
], filename="2222.html")
 

下面是 java 部分的程式碼，是為了生成資料：

package practise;

import java.awt.Point;
import java.util.ArrayList;
import java.util.List;
import source.SourceCode;

public class Intervene extends SourceCode {
	public List<List<Double>> data = new ArrayList<>();

	public static void main(String[] args) {
		Intervene intervene = new Intervene();
		intervene.testDemo001();
	}

	public void testDemo001() {
		Point point1 = new Point(25, 25);
		Point point2 = new Point(75, 75);
		int lamda = 6;
		for (int i = 0; i < 100; i++) {// y 軸
			List<Double> distance = new ArrayList<>();
			for (int j = 0; j < 100; j++) {// x 軸
				Point point = new Point(j, i);
				double x = point.distance(point1) % lamda / lamda;
				double y = point.distance(point2) % lamda / lamda;
				double xx = Math.sin(x * 2 * Math.PI);
				double yy = Math.sin(y * 2 * Math.PI);
				distance.add(xx + yy);
			}
			data.add(distance);
		}
		StringBuffer content = new StringBuffer();
		int size = data.size();
		for (int i = 0; i < size; i++) {
			String text = data.get(i).toString();
			text = text.substring(1, text.length() - 1);
			if (i == 0)
				content.append(text);
			content.append(LINE + text);
		}
		logLong("intervene.log", content.toString());
	}
}
