I'm still confused about the question, but based on your screenshot it looks like your data has an RGB vector that is supposed to represent colors. However, ParaView by default assumes that all data are some physical quantity (like, for example, velocity). The default representation of a vector is to take its magnitude (length) and then feed that through a transfer function. That is where quantities like 29.5804 come from. That one in particular is the smallest magnitude of all your colors.
I assume what you really want is to render the image using the RGB values as colors. There is an option in the Properties panel named "Map Scalars". Uncheck that box and ParaView should show the original colors without using the color map. -Ken On 2/19/15, 8:05 AM, "dragone" <dragon.p...@gmail.com> wrote: >Thanks Buren and Kenneth for the response, > >I reply the email directly to you because I didn´t see the way to do it >through the mailing list. > >I agree with you, I only have the position points (x,y,z) and the rgb >coordinates of the surface.
