core.temporalpoints module

class IMTreatment.core.temporalpoints.TemporalPoints

Bases: object

Class representing a set of time evolving points.

add_pts(pt, time=0.0, unit_times='')

Add a Pointsobject to the existing point set.

Parameters:

• pt (Point object) – The points to add.
• time (number) – time associated to the field.
• unit_time (Unum object) – time unit.

change_unit(axe, new_unit)

Change the unit of an axe.

Parameters:

• axe (string) – ‘y’ for changing the profile y axis unit ‘x’ for changing the profile x axis unit ‘values’ for changing values unit ‘time’ for changing time unit
• new_unit (Unum.unit object or string) – The new unit.

copy()

Return a copy of the velocityfields

crop(intervx=None, intervy=None, intervv=None, intervt=None, full_output=False, ind=False, inplace=False)

Return a croped field in respect with given intervals.

Parameters:

• intervx (array, optional) – interval wanted along x
• intervy (array, optional) – interval wanted along y
• intervv (array, optional) – interval wanted along v
• intervt (array, optional) – interval wanted along time
• full_output (boolean, optional) – If ‘True’, cutting indices are also returned
• inplace (boolean, optional) – If ‘True’, fields are croped in place.

display(sharecb=True, buffer_size=100, cpkw={})

Create a windows to display temporals point sets, controlled by buttons.

Parameters:

• sharecb (boolean) – Do all the vector field serie has to share the same colorbar or not.
• buffer_size (number) – Number of displays to keep in memory (faster, but use memory).
• cpkw (dict) – Drawing argument for points
• control (Display) –
• --------------- –
• display can be controlled using the button, but also the keyboard (The) –
• right arrow or + (space,) –
• left arrow or - (backspace,) –
• arrow (down) –
• arrow –
• + enter (number) –
• p (play the animated fields) –
• + i (number) –
• + t (number) –
• q (close) –
• s (save an image) –

dt

remove_pts(indice)

Remove points of the existing point set.

Parameters:indice (integer or list of integers) – Point indice(s) to remove.

scale(scalex=None, scaley=None, scalev=None, scalet=None, inplace=False)

Scale the point sets.

Parameters:

• scaley, scalev (scalex,) – Scale for the axis and the values.
• inplace (boolean) –

  .

smooth(tos='gaussian', size=None, inplace=False, **kw)

Return a smoothed points field set.

Parameters:

• tos (string, optional) – Type of smoothing, can be ‘uniform’, ‘gaussian’ (default) or ‘lowpass’.
• size (number, optional) – radius of the smoothing for ‘uniform’, radius of the smoothing for ‘gaussian’, cut off frequency for ‘lowpass’ Default are 3 for ‘uniform’, 1 for ‘gaussian’ and 0.1 for ‘ lowpass’.
• inplace (boolean) – If ‘False’, return a smoothed points field else, smooth in place.
• kw (dic) – Additional parameters for ndimage methods (See ndimage documentation)
