如何在 Matlab 中绘制 3D 平面? [英] How can I plot a 3D-plane in Matlab?

问题描述

我想使用从 3 个点计算的向量绘制平面，其中:

I would like to plot a plane using a vector that I calculated from 3 points where:

pointA = [0,0,0];
pointB = [-10,-20,10];
pointC = [10,20,10];

plane1 = cross(pointA-pointB, pointA-pointC)

如何在 3D 中绘制plane1"?

How do I plot 'plane1' in 3D?

推荐答案

这是使用 fill3 绘制平面的简单方法:

Here's an easy way to plot the plane using fill3:

points=[pointA' pointB' pointC']; % using the data given in the question
fill3(points(1,:),points(2,:),points(3,:),'r')
grid on
alpha(0.3)
