Hi,
I would like to simultaneously view 3 planes (XY, YZ, XZ) of an image.
I made a Python macro to do this, but I think its clunky.
I think the right way to do this is to write a plugin representation
similar to
ImageSliceRepresentation but pulling out 3 slices.
-- Would a plugin representation be the right way to go ?
-- Documentation seems to discourage folks a little from messing
with their own representations. If it is the right way to go, is
it feasible in ParaView right now ? I am using 3.12-RC2.
-- To start, based on the MySpecialRepresentation example, I wrote
a "OrthoSliceAlphaRepresentation" that subclasses
ImageSliceRepresentation
but doesn't change anything, and I don't even substitute my own mapper
at this point. I made it a subproxy extending UniformGridRepresentation.
It appears as a Rep. for image data, but the Slice selector in the
display panel is greyed out. Why is this ? (Code snippets below).
-- For the real code I think I should not subclass ImageSliceRepresentation
but copy/rename all that code and alter it, ie having
OrthoSliceAlphaRepresentation
subclass vtkPVDataRepresentation. Is that the way you would do it ?
thanks
Kate

=======================================================================
vtkOrthoSliceAlphaRepresentation is defined like this, and no methods
written yet, just trying to inherit *everything* from
vtkImageSliceRepresentation
class VTK_EXPORT vtkOrthoSliceAlphaRepresentation : public
vtkImageSliceRepresentation
