interfacemethod generatePreview(inputDataset, viewName, useLevelling, useGaussianFilter, gaussianFilterStd, cannyProportion, cannySigma)

Generate a dataset of preview on the slice of the specified view

Parameters:

• inputDataset (ORSModel.ors.Channel) – input dataset
• viewName (str) – a view genealogical name
• useLevelling (bool) – specifies if the window levelling should be used
• useGaussianFilter (bool) – specifies if the Gaussian filter should be used
• gaussianFilterStd (float) – standard deviation of the Gaussian filter
• cannyProportion (float) – pondering factor (between 0.0 and 1.0) of the Canny filter to be added to the gaussian filtered result
• cannySigma (float) – sigma parameter (>= 0) of the Canny filter

Returns:

previewDataset (ORSModel.ors.Channel) – the dataset of the preview

interfacemethod getMeshPoissonReconstruction(aGroupOfRegions, depth=8, scale=1.25, solverDivide=8, isoDivide=8, samplesPerNode=1.0, normalsEvaluation='path plane', inputDataset=None, IProgress=None)

Calls for a Poisson reconstruction on a set of regions.

The regions used in the Poisson reconstruction are only the selected objects contained in the group.

Parameters:

• aGroupOfRegions (ORSModel.ors.Group) – group containing a list of selected regions to use in the Poisson reconstruction. At this time, the only accepted regions are instances of VisualPath.
• depth (int) – Poisson reconstruction parameter depth
• scale (float) – Poisson reconstruction parameter scale
• solverDivide (int) – Poisson reconstruction parameter solverDivide
• isoDivide (int) – Poisson reconstruction parameter isoDivide
• samplesPerNode (float) – Poisson reconstruction parameter samplesPerNode
• normalsEvaluation (str) – technique to evaluate the normals
• inputDataset (ORSModel.ors.Channel) – dataset to be used if the normals are to be evaluated from a dataset
• IProgress (ORSModel.ors.Progress) – progress object

Returns:

newMesh (ORSModel.ors.Mesh) – created mesh obtained by the Poisson reconstruction

classmethod getMinMaxValueLevelling(inputDataset, aView)

Gets the window levelling values for the given dataset in the given view, in data units.

Parameters:

• inputDataset (ORSModel.ors.Channel) – dataset
• aView (ORSModel.ors.View) – a view

Returns:

• minValueLevellingDataArray (float) – min value of window levelling in data
• maxValueLevellingDataArray (float) – max value of window levelling in data
