## GrayscaleModelMaker

Link to code

Wraps command **GrayscaleModelMaker **

title: Grayscale Model Maker

category: Surface Models

description: Create 3D surface models from grayscale data. This module uses Marching Cubes to create an isosurface at a given threshold. The resulting surface consists of triangles that separate a volume into regions below and above the threshold. The resulting surface can be smoothed and decimated. This model works on continuous data while the module Model Maker works on labeled (or discrete) data.

Inputs:

    [Mandatory]
    terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
            Control terminal output

    [Optional]
    InputVolume: (an existing file name)
            Volume containing the input grayscale data.
    OutputGeometry: (a boolean or a file name)
            Output that contains geometry model.
    args: (a string)
            Additional parameters to the command
    decimate: (a float)
            Target reduction during decimation, as a decimal percentage reduction in the number of
            polygons. If 0, no decimation will be done.
    environ: (a dictionary with keys which are a value of type 'str' and with values which
             are a value of type 'str', nipype default value: {})
            Environment variables
    ignore_exception: (a boolean, nipype default value: False)
            Print an error message instead of throwing an exception in case the interface fails to
            run
    name: (a string)
            Name to use for this model.
    pointnormals: (a boolean)
            Calculate the point normals? Calculated point normals make the surface appear smooth.
            Without point normals, the surface will appear faceted.
    smooth: (an integer)
            Number of smoothing iterations. If 0, no smoothing will be done.
    splitnormals: (a boolean)
            Splitting normals is useful for visualizing sharp features. However it creates holes in
            surfaces which affect measurements
    threshold: (a float)
            Grayscale threshold of isosurface. The resulting surface of triangles separates the
            volume into voxels that lie above (inside) and below (outside) the threshold.

Outputs:

    OutputGeometry: (an existing file name)
            Output that contains geometry model.

Inputs:

    [Mandatory]
    terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
            Control terminal output

    [Optional]
    InputVolume: (an existing file name)
            Input label map. The Input Volume drop down menu is populated with the label map volumes
            that are present in the scene, select one from which to generate models.
    args: (a string)
            Additional parameters to the command
    color: (an existing file name)
            Color table to make labels to colors and objects
    debug: (a boolean)
            turn this flag on in order to see debugging output (look in the Error Log window that is
            accessed via the View menu)
    decimate: (a float)
            Chose the target reduction in number of polygons as a decimal percentage (between 0 and
            1) of the number of polygons. Specifies the percentage of triangles to be removed. For
            example, 0.1 means 10% reduction and 0.9 means 90% reduction.
    end: (an integer)
            If you want to specify a continuous range of labels from which to generate models, enter
            the higher label here. Voxel value up to which to continue making models. Skip any
            values with zero voxels.
    environ: (a dictionary with keys which are a value of type 'str' and with values which
             are a value of type 'str', nipype default value: {})
            Environment variables
    filtertype: ('Sinc' or 'Laplacian')
            You can control the type of smoothing done on the models by selecting a filter type of
            either Sinc or Laplacian.
    generateAll: (a boolean)
            Generate models for all labels in the input volume. select this option if you want to
            create all models that correspond to all values in a labelmap volume (using the Joint
            Smoothing option below is useful with this option). Ignores Labels, Start Label, End
            Label settings. Skips label 0.
    ignore_exception: (a boolean, nipype default value: False)
            Print an error message instead of throwing an exception in case the interface fails to
            run
    jointsmooth: (a boolean)
            This will ensure that all resulting models fit together smoothly, like jigsaw puzzle
            pieces. Otherwise the models will be smoothed independently and may overlap.
    labels: (an integer)
            A comma separated list of label values from which to make models. f you specify a list
            of Labels, it will override any start/end label settings. If you click Generate All
            Models it will override the list of labels and any start/end label settings.
    modelSceneFile: (a boolean or a list of items which are a file name)
            Generated models, under a model hierarchy node. Models are imported into Slicer under a
            model hierarchy node, and their colors are set by the color table associated with the
            input label map volume. The model hierarchy node must be created before running the
            model maker, by selecting Create New ModelHierarchy from the Models drop down menu. If
            you're running from the command line, a model hierarchy node in a new mrml scene will be
            created for you.
    name: (a string)
            Name to use for this model. Any text entered in the entry box will be the starting
            string for the created model file names. The label number and the color name will also
            be part of the file name. If making multiple models, use this as a prefix to the label
            and color name.
    pad: (a boolean)
            Pad the input volume with zero value voxels on all 6 faces in order to ensure the
            production of closed surfaces. Sets the origin translation and extent translation so
            that the models still line up with the unpadded input volume.
    pointnormals: (a boolean)
            Turn this flag on if you wish to calculate the normal vectors for the points.
    saveIntermediateModels: (a boolean)
            You can save a copy of the models after each of the intermediate steps (marching cubes,
            smoothing, and decimation if not joint smoothing, otherwise just after decimation).
            These intermediate models are not saved in the mrml file, you have to load them manually
            after turning off deleting temporary files in they python console (View ->Python
            Interactor) using the following command
            slicer.modules.modelmaker.cliModuleLogic().DeleteTemporaryFilesOff().
    skipUnNamed: (a boolean)
            Select this to not generate models from labels that do not have names defined in the
            color look up table associated with the input label map. If true, only models which have
            an entry in the color table will be generated.  If false, generate all models that exist
            within the label range.
    smooth: (an integer)
            Here you can set the number of smoothing iterations for Laplacian smoothing, or the
            degree of the polynomial approximating the windowed Sinc function. Use 0 if you wish no
            smoothing.
    splitnormals: (a boolean)
            Splitting normals is useful for visualizing sharp features. However it creates holes in
            surfaces which affects measurements.
    start: (an integer)
            If you want to specify a continuous range of labels from which to generate models, enter
            the lower label here. Voxel value from which to start making models. Used instead of the
            label list to specify a range (make sure the label list is empty or it will over ride
            this).

Outputs:

    modelSceneFile: (an existing file name)
            Generated models, under a model hierarchy node. Models are imported into Slicer under a
            model hierarchy node, and their colors are set by the color table associated with the
            input label map volume. The model hierarchy node must be created before running the
            model maker, by selecting Create New ModelHierarchy from the Models drop down menu. If
            you're running from the command line, a model hierarchy node in a new mrml scene will be
            created for you.
