DataArray construction examples¶

Example 1: Create a Point resource and add a DataArray with random data

pts = steno3d.core.Point;
pts.Mesh = steno3d.core.Mesh0D;
pts.Mesh.Vertices = rand(100, 3);
dat = steno3d.core.DataArray;
dat.Title = 'Random Point Data';
dat.Array = rand(100, 1);
pts.Data = {                                                 ...
    'Location', 'N',                                         ...
    'Data', dat                                              ...
};
example1 = steno3d.core.Project(                             ...
    'Title', 'Data: Example 1',                              ...
    'Resources', pts                                         ...
);
clear pts dat

Example 2: Create a Surface and add node and cell-center DataArrays

sfc = steno3d.core.Surface;
sfc.Mesh = steno3d.core.Mesh2DGrid;
sfc.Mesh.H1 = ones(5, 1);
sfc.Mesh.H2 = ones(10, 1);
ccValues = rand(5, 10);
datCC = steno3d.core.DataArray;
datCC.Title = 'Random Cell-Centered Data';
datCC.Array = ccValues(:);
nValues = rand(6, 11);
datN = steno3d.core.DataArray;
datN.Title = 'Random Node Data';
datN.Array = nValues(:);
sfc.Data{1} = {                                              ...
    'Location', 'CC',                                        ...
    'Data', datCC                                            ...
};
sfc.Data{2} = {                                              ...
    'Location', 'N',                                         ...
    'Data', datN                                             ...
};
example2 = steno3d.core.Project(                             ...
    'Title', 'Data: Example 2',                              ...
    'Resources', sfc                                         ...
);
clear sfc datCC datN ccValues nValues

You can run the above examples with:

steno3d.examples.core.data

Then plot the projects with:

example1.plot(); % etc...
