Method Details [hide private]

__init__(self, scale, center=ORIGIN, ref_face_idx=1, ref_face_normal_along=Z_AXIS, ref_edge_idx=1, ref_edge_along=X_AXIS)
(Constructor)

 

Create an instance.

Parameters:
  • scale (float) - multiplicative scaling factor
  • center (numpy.array) - the center of the polyhedron
  • ref_face_idx (int) - specifies which of this polyhedron's available reference faces (symmetry unique faces sorted by decreasing area) to use in the alignment
  • ref_face_normal_along (numpy.array triple) - specifies the vector along which the reference face normal will be aligned
  • ref_edge_idx (int) - specifies which of the reference faces available reference edges (symmetry unique edges sorted by decreasing length) to use in the alignment
  • ref_edge_along (numpy.array triple) - specifies the vector along which the reference edge will be aligned
Overrides: object.__init__

getEdgeLength(self, circumradius)

 

Return the edge length.

Parameters:
  • circumradius (float) - circumradius in Angstrom
Returns: float
edge length in Angstrom

getCircumRadius(self, length)

 

Return the circumradius.

Parameters:
  • length (float) - length in Angstrom
Returns: float
circumradius in Angstrom

getVolume(self, length)

 

Return the volume.

Parameters:
  • length (float) - length in Angstrom
Returns: float
volume in cubic Angstrom
