Syntax

plot(shp)
plot(shp,Name=Value)
h = plot(___)

Description

plot(shp) plots alpha shape shp in a figure window.

example

Open Live Script

Create a set of 3-D points.

[x1,y1,z1] = sphere(24);
x1 = x1(:);
y1 = y1(:);
z1 = z1(:);
x2 = x1 + 5;
P = [x1 y1 z1; x2 y1 z1];
P = unique(P,"rows");

Create and plot an alpha shape using an alpha radius of 1.5.

shp = alphaShape(P,1.5);
plot(shp)

3-D alpha shape showing two triangulated spheres, one centered at the origin and one offset to the right

Plot the alpha shape with a specified color and transparency factor.

plot(shp,FaceColor="red",FaceAlpha=0.1)

3-D alpha shape of two spheres plotted with red face color and high transparency, showing the triangulated mesh through the translucent surfaces

Input Arguments

Example: shp = alphaShape(x,y) creates a 2-D alphaShape object from the (x,y) point coordinates.

Output Arguments
