reflect_base_points

reflect_base_points(points, domain_size)

Relects a set of points about the faces of a given domain

Parameters:

• points (ndarray) – The coordinates of the points to be reflected. The points should be in the coordinate system corresponding to the the domain.

• domain_size (list or array) –

  Controls the size and shape of the domain, as follows:

  shape	result
  [x, y, z]	Points will be reflected about all 6 faces
  [x, y, 0]	Points will be relfected about the x and y faces
  [r, z]	Points will be reflected above and below the end faces and across the perimeter
  [r, 0]	Points will be reflected across the perimeter
  [r]	Points will be reflected across the outer surface

• f (float) – The fraction of points which should be reflected. The default is 1 which reflects all the points in the domain, but this can lead to a lot of unnecessary points, so setting to 0.1 or 0.2 helps speed, but risks that the tessellation may not have smooth faces if not enough points are reflected.

Returns:

points – The coordinates of the original points plus the new reflected points

Return type:

ndarray
