Syntax

plot(shp)

plot(shp,Name,Value)

h = plot(___)

Description

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

plot(shp,Name,Value) uses additional options specified by one or more Name,Value pair arguments. For a complete list of allowed Name,Value pairs, see Patch Properties.

h = plot(___) returns a handle to a Patch object using any of the previous syntaxes.

Examples

Plot 3-D Alpha Shape and Modify Patch Properties

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)

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

plot(shp,'FaceColor','red','FaceAlpha',0.1)

Input Arguments

shp — Alpha shape

alphaShape object

Alpha shape, specified as an alphaShape object. For more information, see alphaShape.

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

Output Arguments

h — Handle to Patch object

handle

Handle to Patch object, returned as a handle. For more information, see Introduction to Patch Objects.
