3D color map in Omniverse


I am trying to construct 3D color map in Omniverse like the below image.

(Referenced by : Radiation 101 - Berkeley RadWatch)

I want to implement a color change from blue to red depending on the amount of radiation.

I’ve already implemented the calculation of radiation in Omni, but I don’t know how to implement the color changes in Omni.

ㅑ look forward to your reply.

Thank you !

Hello @swimpark! Very cool! I will see if I can get a developer to help!

Hi @swimpark
You might want to checkout the use of Primvar data displayColor in Omniverse.

And then you might look into writing displayColor as USD time sampled value to animate it over time.

Hope that helps
