vtk CAD graphic

Display block topology entities (k-points,lines,surfaces,bodies,…)

class postprocess.xcVtk.CAD_model.vtk_CAD_graphic.DisplaySettingsBlockTopo

Bases: postprocess.xcVtk.vtk_graphic_base.DisplaySettings

Define graphic output.

defineLocalAxes(setToDisplay)

Define the local axes of the blocks.

Parameters

setToDisplay – set of elements to be displayed.

defineMeshScene(displayCellTypes)

Define mesh scene on ouput display.

Parameters

displayCellTypes – types of cell to be displayed.

displayBlockEntities(setToDisplay, caption, displayCellTypes, fileName=None)

Display geometric entities (points, lines, surfaces and volumes)

Parameters

  • setToDisplay – set to be represented

  • caption – text to display in the graphic.

  • displayCellTypes – types of cell to be displayed.

  • fileName – name of the graphic file to create (if None then -> screen window).

displayBlocks(setToDisplay, displayLocalAxes=True, caption='', fileName=None, displayCellTypes=['lines', 'faces', 'bodies'])

Display the element local axes.

Parameters

  • setToDisplay – set of elements to be displayed (defaults to total set)

  • displayLocalAxes – if true, show also local axes of entities.

  • caption – text to display in the graphic

  • fileName – file name to store the image. If none -> window on screen.

  • displayCellTypes – types of cell to be displayed.

displayLocalAxes(setToDisplay, caption, displayCellTypes, fileName=None)

Display the element local axes.

Parameters

  • setToDisplay – set of elements to be displayed (defaults to total set)

  • caption – text to display in the graphic

  • displayCellTypes – types of cell to be displayed.

  • fileName – file name to store the image. If none -> window on screen.

vtk CAD mesh

Block topology displaying routines using VTK.

postprocess.xcVtk.CAD_model.cad_mesh.VtkCargaIdsCells(uGrid, setToDraw, entTypeName)
postprocess.xcVtk.CAD_model.cad_mesh.VtkCargaIdsKPts(uGrid, setToDraw)
postprocess.xcVtk.CAD_model.cad_mesh.VtkDibujaIdsCells(uGrid, setToDraw, entTypeName, renderer)

Create cell labels.

postprocess.xcVtk.CAD_model.cad_mesh.VtkDibujaIdsKPts(uGrid, setToDraw, renderer)

Draw the point labels.

postprocess.xcVtk.CAD_model.cad_mesh.vtk_define_cells_actor(gridRecord, renderer, reprType, color=[0.09706014181677136, 0.16131221412663266, 0.8528529946084227])

Actor for lines and surfaces.

Parameters

  • gridRecord –

  • rendered – VTK renderer.

  • reprType – representation type (points, wireframe or surface).

postprocess.xcVtk.CAD_model.cad_mesh.vtk_define_kpoint_actor(recordGrid, renderer, radius)

Returns a vtkActor to represent key-points in a rendering scene. It defines the scale, orientation, rendering properties, textures, …

Variables

  • recordGrid – unstructured grid (generic data set) to which incorporate the actor KPoint

  • renderer – name of the renderer (lights, views, …) to be used in the display

  • radius – radius of the spheres to be employed in the KPoints representation

postprocess.xcVtk.CAD_model.cad_mesh.vtk_load_mesh_data(gridRecord)

Creates an VTK unstructured grid from the block topology entities.

Parameters

gridRecord – instance of the RecordDefGrid class.

vtk array data

postprocess.xcVtk.CAD_model.create_array_set_data.VtkCreaStrArraySetData(setToDraw, entTypeName, attr)

Creates an array of strings with information associated to the points and cells.

Parameters

  • setToDraw – set of entities to be displayed

  • entTypeName – type of entities to be displayed (“pnts”, “lines”, “nodes”, “elementos”)

  • attr – attribute to be stored in the array
