= Transitioning the Fiducials Module =

The Fiducials module in Slicer 2 has grown over the course of its lifetime to encompass much functionality. Currently each fiducial point must be on a single list. Points can be selected or unselected, and lists as a whole can be visible or invisible in the 3D view. Fiducials can be set on objects in 3D or in the 2d slice windows.

Current uses for fiducials in Slicer 2:

* marking model parts
* marking world coordinate system points
* marking registration points
* volume markers
* endoscopic paths
* targets for robotic control

Additional uses for fiducials in Slicer 3:

* algorithm seed points, passed to CLI modules
* 2D markers on slices

= Preliminary Implementation Notes =

From a meeting with Steve P, Alex Y, Nicole A, Wendy P on Jul 24/06:

* the fiducials list should be transformable
* make each fiducial a separate node? no...
* make them a subclass of models, with scalar fields of selected, text, colour, etc.
* serialise fiducials to disk in ascii format so that users can read point information in plain text
* create ficucials -> text first, Steve will do click/select in 3d
* use kwwidgets for the 2d gui
** use the multicolumn list box, like in the Transform display
** change the node, the observer will trigger and change the rendering, change point callback used.
** Set up columns for x, y, z,colour, text
* Fiducials module: vtkSlicerFiducialsGui, knows about fiducial nodes, set and observe mrml and process mrml events method, and process widget events
* Fiducials list - sub class of model node
** model display node subclass to fiducial display node, put font information in there, offset, wwidgets caption?
** use model field data for selected/unselected, geometry
