As a	CEP developer
I would like to	add easily manipulate array of data (values, signals, vectors...) to any type of component (not MeshComponent nor ImageComponent)
So that	I can visualize/interact data as colors on a mesh, as graph/curve
Epic/Topics	Interface Data

Description / Overview

The epic is called "Interface Data" or how to include 1D temporal signal in CamiTK.

This is a new facet for Component that enables storage, manipulation, visualization and interaction with/of array of data. The idea is to offer data abstraction and minimal default behaviour for signal and temporal values.

In the design stage, first check:

• Check the Pulse project to check how they store the signals
• Check the work done by Nico (see incubator-local/respirm CEP) in order to handle 1D signal and their representation using a dedicated viewer based on vtkChart library (and some action to process them). In particular check the viewer and the defined actions.
• Check open-source application that help manipulate data and display charts to deduce best practices
• Check for standard in signal processing data format and processing library (if any)

One idea would be to be able to use a python interface/shell/script in order to process the signal directly from a console...

Hints

As for any creation of interface in CamiTK, this can be done following these steps:

• Create a new interface that add the management of a list of vtkDataArray in Component
• Create the corresponding helper class
• Create the corresponding viewer (using vtkChart and the possibility to add data as if it was a live physiological signal) and integrate it to camitk-imp
• Create another viewer to display data in a table/spreadsheet
• Take into account the fact that MeshComponent can project the data as colors
• move addPointData/addCellData in InterfaceGeometry or to the new InterfaceData interface (may be use an enum for FREE, ATTACHED_TO_CELLS, ATTACHED_TO_POINTS etc...

Acceptance tests

• a new tutorial component that shows how to add/remove/show these data in the new viewer
• a new tutorial MeshComponent that shows how data can be displayed directly on the mesh surface
• a new tutorial that shows generates random value based on a sinus function to show how update/acquisition can be done
