3D color map in Omniverse

swimpark · March 16, 2022, 9:05am

Hi,

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

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 !

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
