I’m curious if there is a way to color a dataset by an attribute then set the opacity mapping via a separate array in the same dataset.
For example, I often have a volume of data with two arrays: the data array (e.g. some physical property like conductivity) and an array representing the uncertainty values. I would like to color my volume of data by the data array and set its transparency based on the uncertainty array.
Is there a way to do this in ParaView currently? If not, I was thinking I might create a Python Algorithm plugin to do this…my thought would be that the transparency would need to be set cellwise… is this possible/is there a good way to achieve my goal besides just adding a new RGBA array as I would like to still use predefined colormaps?
