interfacemethod editObjectFromGroupOfPaths(aGroupOfRegions, operationToPerform, IProgress=None)

Edits an object from a set of regions using a Poisson reconstruction.

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.
  • operationToPerform (str) – operation to perform Should be one of: [‘add’, ‘remove’, ‘intersect’, ‘replace’].
  • IProgress (ORSModel.ors.Progress) – progress object
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 getMeshFromGroupOfPaths(aGroupOfRegions, meshTitle, meshColor, IProgress=None)

Creates a mesh from a set of regions using a Poisson reconstruction.

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

Parameters:

  • meshColor (ORSModel.ors.Color) – the new mesh color
  • IProgress (ORSModel.ors.Progress) – progress object
Returns:

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

Deprecated since version 3.6: Use getMeshFromGroupOfPaths.

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
getMeshToCut()
classmethod getMinMaxValueLevelling(inputDataset, aView)

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

Parameters:
Returns:
  • minValueLevellingDataArray (float) – min value of window levelling in data
  • maxValueLevellingDataArray (float) – max value of window levelling in data
interfacemethod getMultiROIFromGroupOfPaths(aGroupOfRegions, structuredGridShapeOfReference, multiROITitle, IProgress=None)
