Subject: [Insight-developers] ROI Spatial Object



Hi,

I'd like to suggest a better name for the ROI spatial objects.

itkROISpatialObjects are slice-based objects - they require points to be 
stored as "strands."   A strand holds either x, y, or z constant while 
the other two coordinates vary to define the object's intersection with 
the slice.

Since the data container is the only difference between this and other 
spatial objects, couldn't we instead call these StrandSpatialObjects or 
SlicedSpatialObjects or derive from blobSpatialObjects to be 
SlicedBlobSpatialObjects?

All of the spatial objects can actually be used as ROIs...as can 
itkSpatialFunctions, etc.

Also - in the comments of itkROISpatialObject it is stated that some of 
the definitions of IsInside are ad-hoc in the other spatial 
objects...please let me know which ones and I will fix them.

Thanks,
Stephen
