== Usage ==

As an alternative to [[MATLAB/TriSurf|trisurf]], consider:

{{{
% Create a rectangular grid.
[X,Y,Z] = meshgrid(linspace(-3,3,20), linspace(-3,3,20), linspace(-3,3,20));

% Identify the points within a region of integration.
roi = (X>=0 & X<=sqrt(4-Z.^2-Y.^2)) & (Y>=0 & Y<=sqrt(4-Z.^2) & (Z>=0 & Z<=1));

% Calculate the convex hull of this ROI and plot.
K = convhulln([X(roi), Y(roi), Z(roi)]);
figure;
patch('Faces', K, 'Vertices', [X(roi), Y(roi), Z(roi)]);
}}}
