                             Contour

Class that shows a scalar field by contour surfaces. The contour surfaces can either be colored or grey-scaled, depending on the lookup table used. This class can also be used to generate iso surfaces.

Instance Methods [hide private]
 
__init__(self, scene, data_collector, viewport=0, lut='color', cell_to_point=False, outline=True)
Initialise the Contour.
Boolean
_isModified(self)
Return whether the Contour or DataCollector has been modified.
 
_render(self, scene)
Render the contour.

Method Details [hide private]

__init__(self, scene, data_collector, viewport=0, lut='color', cell_to_point=False, outline=True)
(Constructor)

 

Initialise the Contour.

Parameters:
  • scene (Scene object) - Scene in which objects are to be rendered on
  • data_collector (DataCollector object) - Deal with source of data for visualisation
  • viewport (Viewport constant) - Viewport in which objects are to be rendered on
  • lut (Lut constant) - Lookup table color scheme
  • cell_to_point (Boolean) - Converts cell data to point data (by averaging)
  • outline (Boolean) - Places an outline around the domain surface
Overrides: contourmodule.ContourModule.__init__

Attention: The source can either be point or cell data. If the source is cell data, a conversion to point data may or may not be required, in order for the object to be rendered correctly. If a conversion is needed, the 'cell_to_point' flag must be set to 'True', otherwise 'False' (which is the default). On occasions, an inaccurate object may be rendered from cell data even after conversion.

_isModified(self)

 

Return whether the Contour or DataCollector has been modified.

Returns: Boolean
True or False

_render(self, scene)

 

Render the contour.

Parameters:
  • scene (Scene object) - Scene in which objects are to be rendered on
