Hi David,
Interesting, I just checked this out using ParaView and you are correct
if a transform filter is applied. However in the display tab of ParaView if
you transform there then the colouring is unaffected. Never noticed this
because we have been just transforming using the transform in th
Andrew,
I may have missed something in the discussion, but you typically do
not want to set colors via SetVectors as you mentioned (
p->GetPointData()->SetVectors(rgb); )
My understanding is that whatever is set with SetVectors will be
transformed when the data set is transformed. I.e. if you rot
I also attach the vtp file I created from your text file. Set the
point size to 11 to make the points more obvious.

There is a problem in your C++ code.
You need to do something like this (these are snippets from my code):
vtkSmartPointer rgb =
vtkSmartPointer::New();
rgb->SetNumberOfComponents(3); // red,green,blue
rgb->SetName("color");
...
Fill the unsigned array with the rgb values.
...
Then do:

And here is an example python programmable filter that you can adapt

Hi all,
Following David's suggestion, I came up with the code attached that turns
the starting data file (rgb.txt, of the type [X Y Z R G B] (the first three
vector columns specify the location of the single point and the last three
one its color in RGB space)) into a parsed vtp format. Unfortuna
