[vtkusers] vtkFixedPointRayCastImage question

[Krishna Katamneni]

When set like this

m_vtkMIPVolumeMapper->SetBlendModeToMaximumIntensity();  //Max Mip

Only maximum values from the input volume(though input
contains negative values) are considered for mapping.
All negative values are ignored because they are not maximum values when
compared to the other positive  values.

If you want your output to contain all the maximum values (irrespective of
the sign of the data), I think,  you have to implement your own
ray-casting algorithm.
