A lot of water simulation in the CG industry is done with this product: http://www.realflow.com/product/realflow/
A LOT of computational power goes into simulating these fluids in order for them to look natural. However, our current algorithms are just not fast enough in order for us to get perfect results with the alloted amount of computational power. Aditionally, once we simulate it we have to render the damned thing and that takes time also. Eventually it is considered "good enough". I saw no problems with the fluids in the trailer, although it is very possible they will go for a few more tries at rendering it before the final print is made. Trailers do not always use final prints or however you want to put it.
(we being the royal we)
TIL Realflow isn't the industry standard for fluid / massive particle simulation... I've been lied to. Just look at this tech demo. These movies are huge! How could it be this widely used without someone alerting me of it's existence?

It all comes together in a main 3D package, for this they used Maya. <3 (I love my software)

You bet it did :) About the mitral valve, well I should say I didn't know that at the time of modelling, I am too tired to edit it now, but will definitely consider changing it whenever I can...
And about the future projects, I am in a dilemma, whether to add liquid inside these chambers using realflow or go to pathologies omitting the physiology... I still have a fear that adding blood could make the model clumsy, but I will give it a try once... If that fails, I'll go directly to various pathologies and upload them sketchfab soon....
And thank you very much for your kind comments.. :)
It's a fluid dynamics simulation. Check out RealFlow's website if you're interested in this type of thing, they've got an impressive showreel on there (but no option to link to it directly)
It is a pricey one indeed...hence why we still use RF5 :). I'd love to upgrade to the newest versions, but just not enough consistent need. We have rented licenses for Maxwell and RF2012 before though. That worked out really well as a single project solution. I believe it's $250 for the week.
You don't.
This is modelled in 3D. Most likely using a liquid simulation (like realflow). You can't model this in Photoshop.
Then it has been given a black material, lit and rendered.
Optionally, if you are good at painting you could try painting it.
Awesome! The fluid looks really great. I do work like this in CGI with a program called Realflow and I could have sworn the fluid was CG had i not seen this bit. Great work!
Agreed. Looks completely CG. Obvious texture and lighting, plus the shadows. And the water looks like real flow.
