Water Temperatures

[Jkirch]

Hi,

 

I am working on a project to show the temperature change of water as it moves through a lagoon.

 

I am using 3ds max and Realflow and I was wondering what the best way to show this would be.

 

It would be great if I could make the water that comes in, which is hot, red and as it cools and exits turn blue.

 

Any recommendations?

Thanks for all the help.

I don't know RF at all so I'm just skylarking...

 

change color over time - probably the easiest and least satisfactory.

 

change color over time modulated by slowness - assumes faster is staying together and not mixing therefore not cooling. Might be kinda easy and might actually look ok

 

same as above but use velocity not speed - catches fast eddies

 

write a heat exchange mechanism - no idea how possible this is. iterate particles. each particle moves temperature to the direction of the average of its immediate neighbours (note: I am not a fluids expert). It should be possible. Don't know what "getting neighbours" would be like. Suspect it's slow.

Changing colors over time would be great, but I'm new to realflow and I have no idea how.

 

I've searched around a little but I can't find any info on how.

 

Any suggestions?

Don't know if it supports vertex colors but if you can manipulate them along with particle age it should be a piece of cake..

 

Or just simulate diffusion in 2D and use that as mix texture..
