Fluid dynamics and simulation with RealFlow 2015

Below is a fun web project for display using ‘Chrome’ as your browser and part of the Chrome Web experiments done by Evan Wallace. You can play around with some realtime water simulations with light and the resulting surface turbulence.

It shows simply what can be done simply in your web based browser.

It’s interactive, realtime and fun!

If you want to do real productive fluid rendering simulations of your own, splashes for digital media, digital photography, animations or any creative application you will need RealFlow 2015 to create your own scenes within your own modeller ( 3D Max, Maya, Cinema4D, Lightwave and others ) with amazing results.

BASIC FLUIDS SIMULATION WORKFLOW WITH CINEMA 4D AND REALFLOW WEBINAR

MARCH 23 7-8PM AEDT

We have been able to organise a webinar that was originally run a month ago but at times that made it impossible to participate – so we are happy to announce a new dat form a repeat with the same presenter online at a time that is easier for local Australian and New Zealand attendees.

 


Time 7-8pm Sydney/Melbourne/Canberra time
Wednesday March 23 online
Please fill in your details here and we will have your Gotomeeting registration link confirmed


In the past, advanced fluids simulations were reserved for large film productions because of their immense cost, high-end software requirements and massive render times. 

There are in fact numerous uses for these types of simulations: they are, for example, an integral part of advanced motion design and professional product visualizations. Even though the tools required to create these simulations have become notably more affordable and the advances in processor architecture even make it possible for freelancers and smaller studios to meet the requirements for rendering these simulations, the belief is still prevalent that convincing fluids simulations can only be created by experts with a corresponding scientific background.

In this basic skills webinar, Danish 3D designer and Cinema 4D lead instructor Thomas Andreasen shows that this belief is no more than a myth. Thomas, who himself only recently started creating his own fluids simulations, shows that Cinema 4D and Next Limit RealFlow have clearly lowered the bar significantly. Thomas uses a perfume advert as an example for demonstrating how to quickly create visually stunning results.

This webinar lasts about one hour and you can send questions during the session via chat. To allow more time for the webinar content, we will collect your questions and answer them comprehensively with the help of product specialists from Next Limit. We will make the answers available for all attendees as a downloadable FAQ document!

Basic Fluids Simulation with Cinema 4d and RealFlow

Recently there was hosted a webinar on using Fluid simulation, Basic Fluids Simulation Workflow with Cinema 4D and RealFlow. It was hosted at a European time that made it very difficult for us in the East to view so we are hoping to announce a local timed version fairly soon.

But as promised, we recorded this webinar and have made it available online so you can view it at your leisure. If you were not able to experience the live stream you can still see how easy it is to create impressive, realistic-looking fluids simulations. You can also download the Cinema 4D, RealFlow and After Effects setups so you can recreate each step if the simulation on your own computer. A short set of  instructions is also included.

ReaFlow with Maxwell Render

Trojan Horse was a Unicorn

Juice.pl

Emanuele Niri describes how the amazing opening and closing titles for ‘Trojan horse was a Unicorn’ were made using RealFlow. THU is a unique four-day Digital Art Rave.

About the company

The fluid job was carried out on behalf of Juice.pl based in Warsaw, Poland. It is a visual creative studio with four branches worldwide specializing in CG, VFX Post production, animation, rendering, compositing and sound design.

The Problem

The main goal of the simulation part was focused on the creation of a dynamic energy fluid in order to convey a sense of sparkling light upon darkness. Therefore making it flow across the various elements in the scene to give the impression of bringing the apparent state of death back to life once again. A short timing production of eight weeks overall out of which only four were spent on the fluid side alone presented a hard task due to the number of shots.  The team was composed of Juice.pl’s in house artists. The producer Natalia Lasota was in charge, alongside a network of external freelance artists under the brilliant art direction of Michał Misiński. A pressure we were up against was a tight deadline which sometimes forced me to compromise aspects of the simulations.

The Solution

RealFlow was used to meet our requirements in various ways. The new Spline tools available in RF2015 were of great help and extensively used alongside the new VDB meshing which helped me a lot when it came to blending more emitters into one.

I generally drew lots of curves and constrained them to geometry within Maya then exported them to RF2015 to create Spline driven forces, which in turn enabled me to keep the streams flowing seamlessly across the surfaces.

The hardest part was to keep the fluid attached to the surface of the animated characters while retaining a natural flowing feel and the required speed of the streams and in this respect the new Spline tool inside RF2015 was really spot-on.

Rendering was carried out by Juice.pl using V-Ray and of course the Maxwell preview within RF2015 was used to visualize most RnD stuff that preceded the work.

I have used RealFlow for the past seven years on almost every work that is particles or instance related. I mostly use RealFlow for liquids and viscous fluids of any kind, though I also like it to sketch out quick ideas that could be further developed for different purposes and in most cases it always turns out to be the right choice.

I guess nowadays RealFlow is fully adaptable to almost any pipeline and it is like one of those ingredients you can’t miss in a good kitchen. I will most certainly use RealFlow again, and I wish a bright future for it to be as great as its present and past time and time again.

The 3D platforms we used were Maya and Houdini. I operate with Windows 7 64-bit. The hardware at my disposal is: 2x Xeon x5650 @2.67ghz, 48gb ram.

The greatest benefit of RealFlow is that it is simple and intuitive at first sight and a truly responsive group of developers and friends are always there to help you.

Special thanks to the whole team at Juice for the opportunity they gave me to be part of it and particularly Michał Misiński, Łukasz Dziedziński and Jakub Knapik for coordinating the huge amount of work smoothly and patiently.

Thanks also to Igor Žanić and his alchemies whose help on one shot came from outside as an unexpected one off magical touch.

Realflow 2015 Waterline Magazine

Waterline magazine “Scripting with RealFlow” is a free PDF with almost 100 pages.

The introduction to Python teaches you how to work with vectors, use RealFlow’s scripting editors, differentiate between variables and data types, and create user interfaces.

You will also find complete projects:
A basic coin stacker script, particle swapping, colour blending, crown splashes, export management, and a script for calculating velocities from ocean statistical spectrum waves. Illustrations, step-by-step explanations, and complete listings will help you to understand the principles behind scripting.
