comparing multiple clouds

Hi,
I am doing some research about motionblur between different models. I have 8 models of the same object (as you can see below), and want to compare all this models to 1 reference model (in this case the model v0). All the models are already correctly alligned. To detect motion blur I was thinking to compute the cloud to cloud distance, because the motion blur would lead to a rather faded model with some differences. But when doing this all the to be compared models have a different color scalar scale, when they are created.

my question: is there a way to correctly compare this clouds in the same 'scale'? or is there another way to compute motion blur (faded model) and making this visible in CC?

as you can see there should be a large difference in color, but the scales are just set different, so cant compare them to eachother.

Yes, you have to create an 'absolute' color scale, with fixed steps/values. See https://www.cloudcompare.org/doc/wiki/i ... es_Manager.
