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 the display
tab of ParaView.
I agree with you is will be safer to prefer
p->GetPointData()->SetScalars(rgb);
Thanks
Andrew
