Hi Huy, It sounds like you did exactly the right thing. The description in my previous message was slightly different because I thought you wanted the surface and gradient both from the same volume data. Best, Elaine ----- Elaine C.

Hi Elaine,
I tried what you told me, and it seems to work like what I expected. But I just want to confirm what I did is right as I don't fully understand the guide on the webpage you gave me.
My question: I have volume A & B. I want to color the surface of volume A by the gradient of volume B.
What I did: - I chose iso surface display of volume A using Volume Viewer. - Go to Tools/Volume Data/Surface Color, choose Color Surface A, using B gradient norm, then Color.
Best regards, Huy
