Thanks for the replies. The show colour surfaces tool uses the right
kind of data as input, but I need to do a further level of treatment.
In my volume, I have the background = 0 and particles coloured in =
{1,2,3...150,000}.
I have different types of information about these particles, say
density, or volume or temperature, which I know from an external
source, and I would like to visualise this data plotted on the
particles.
I would therefore like to attach an "Integer Lookup Table" to do the
following lookup:
0 -> 0
1 -> temperature of particle 1, say 32.1
2 -> temperature of particle 1, say 24.7
3 -> 56.2
...
and so on so that I see temperature of each grain in my volume. Is
there a way to achieve this with a lookup table, or should I write a
macro that reads in the table above and goes through changing all the
values?
