[vtkusers] custom raycasting function?

[Adrian Albert]

Hi All,


I was wondering if there was an easy way of defining a user raycasting
compositing function. I am using vtkFiexdPointVolumeRayCastMapper, to which
I am feeding 4 scalar components. I would like to write my own compositing
function that could be able to work not only on a single component of the 4
components, but to pass all 4 components to a transfer function (which I
also have to write such that it accepts 4 components instead of one).

Thanks!

Adrian
