Examples
Create and plot an alpha shape.
[x, y] = meshgrid(linspace(-1, 1, 16));
P = [x(:), y(:)];
P(hypot(P(:, 1), P(:, 2)) > 1, :) = [];
SHP = alphaShape(P, 0.3);
A = area(SHP);
plot(SHP)
hold('on')
plot(P(:, 1), P(:, 2), '.')
SHP = alphaShape(P)
SHP = alphaShape(x, y)
SHP = alphaShape(x, y, z)
SHP = alphaShape(..., alpha)
SHP = alphaShape(..., 'HoleThreshold', value, 'RegionThreshold', value)
K = boundaryFacets(SHP)
A = area(SHP)
plot(SHP)
alphaShape stores points and alpha parameters for boundary and shape queries.
[x, y] = meshgrid(linspace(-1, 1, 16));
P = [x(:), y(:)];
P(hypot(P(:, 1), P(:, 2)) > 1, :) = [];
SHP = alphaShape(P, 0.3);
A = area(SHP);
plot(SHP)
hold('on')
