在MATLAB中使用plot3绘制圆锥 [英] Using plot3 for drawing cones in MATLAB

问题描述

我正在寻找一种在3D冲浪图中的特定位置绘制圆锥的方法.圆锥体是否也可以达到50％透明?

I'm looking for a way to draw a cone at a specific location in a 3D surf plot. Would it also be possible to have the cone 50% transparent?

现在，我正在使用surf函数绘制基本的3d环境.我正在尝试使用功能plot3在特定位置绘制具有特定尺寸的圆锥.

Right now I'm drawing a basic 3d environment using the surf function. I'm trying to use the function plot3 to draw a cone with specific dimensions at a specific location.

推荐答案

下面的代码通过使用t=[0;1]将圆柱体捏在零和一之间来创建圆锥体.然后使用alpha(...)功能风扇设置透明度.要重新定位圆柱体，必须在x，y或z上添加一个值或执行旋转操作(超出此答案的范围).

The following code creates a cone by pinching a cylinder between zero and one with t=[0;1]. The alpha(...) function fan then be used to set the transparency. To reposition a cylinder you must add a value to the x,y, or z or perform a rotation (beyond the scope of this answer).

t = [0;1];
[X,Y,Z] = cylinder(t);

figure;
clf;

surf(X,Y,Z);
alpha(.5)

hold all

surf(X+1,Y,Z);
alpha(.5);
axis equal
