Function Documentation

rotateGrids()

PyPO.System.System.rotateGrids	(		self,
			name,
			rotation,
			obj = "element",
			mode = "relative",
			pivot = None,
			keep_pol = False )

Rotate reflector grids.

Apply a rotation, around a center of rotation, to a reflector, group or frame. Note that an absolute orientation rotates the orientation such that it is oriented w.r.t. the z-axis. In this case, the pivot defaults to the origin and not to the specified pivot. In the case that a PO field and/or a PO current is associated with the reflector, the polarisation of the field and/or current is rotated along as well. This can be disabled by setting the "keep_pol" parameter to "True".

Parameters

name	Reflector name or list of reflector names.
rotation	Numpy ndarray of length 3, containing rotation angles around x, y and z axes, in degrees.
obj	Whether the name corresponds to a single element or group.
mode	Apply rotation relative ('relative') to current orientation, or rotate to specified orientation ('absolute').
pivot	Numpy ndarray of length 3, containing pivot x, y and z co-ordinates, in mm. Defaults to pos.
keep_pol	Keep polarisation of a field/current defined on the surface, if present.

translateGrids()

PyPO.System.System.translateGrids	(		self,
			name,
			translation,
			obj = "element",
			mode = "relative" )

Translate reflector grids.

Apply a translation to a reflector, group or frame. If the translation is absolute, the object will be translated such that its internal position parameter coincides with the specified translation.

Parameters

name	Reflector name or list of reflector names.
translation	Numpy ndarray of length 3, containing translation x, y and z co-ordinates, in mm.
obj	Whether the name corresponds to a single element or group.
mode	Apply translation relative ('relative') to current position, or move to specified position ('absolute').
