Class EdgeExtractor

                     EdgeExtractor

Objects can be used in conjunction with EdgeData objects to extract piecewise-linear edges from data-records. Each linear segment of an edge is rendered as a truncated cone, hence there is a radius associated with each point on the edge and a color associated with each linear segment on the edge.

Method Details [hide private]

__init__(self, pointListMap=lambda dataRecord: dataRecord.getPointList(), radiusListMap=lambda dataRecord: 1.0, colorValListMap=lambda dataRecord: 0, radiusScale=1.0)
(Constructor)

 

Constructor.

Parameters:
  • pointListMap (callable) - Callable which takes a single data-record as an argument and returns a list of coordinates representing the end-points of the linear segments of the edge.
  • radiusListMap (callable) - Callable which takes a single data-record as an argument and returns a list of radii values.
  • colorValListMap (callable) - Callable which takes a single data-record as an argument and returns a list of color values. Each color value is associated with a linear segment of the edge.
  • radiusScale (float) - Scale which is multiplied by all radii.
Overrides: object.__init__

getRadiusList(self, dataRecord)

 

Returns the radii associated with each segment end-point.

Returns: sequence of floats
Sequence of float radii values.

getPointList(self, dataRecord)

 

Returns the coordinates (3 float-element sequence) of each segment end-point.

Returns: sequence of coordinates
Sequence of coordinate values.

getColorValList(self, dataRecord)

 

Returns the color of each segment.

Returns: sequence of colors
Sequence of color objects.
