VOXEL-BASED GASEOUS FLUID DYNAMICS
TurbulenceFD's simulation pipeline implements a voxel-based solver based on the incompressible Navier Stokes equations. That means it uses a voxel grid to describe the volumetric clouds of smoke and fire and solves the equations that describe the motion of fluid on that grid. For each voxel TurbulenceFD calculates the velocity of the fluid as well as several channels to describe properties like temperature, smoke density, amount of fuel, etc. This simulation process produces a voxel grid for each frame, which is cached on disk for use by the Volumetric Renderer.
To setup a fluid simulation, the artist uses any type of geometric object or particle system to paint the sources of smoke, heat, fuel, etc. in space. The flow then carries along these emissions in a physically plausbile way that creates the realistic look of fire, explosions, vapor, clouds, dust and much more.
PULL ALL THE STOPS ON YOUR CPU
The biggest technological challenge in fluid simulation is the handling of the large amounts of data that a sequence of voxel grids requires. That is why TurbulenceFD's simulation pipeline has been designed from the ground up to optimize performance. This includes a careful selection of efficient numerical methods that provide high accuracy and stability throughout the simulation pipeline. And implementing this pipeline using the latest High Performance Computing technology to optimally exploit Memory Caches, Multi-Core CPUs and advanced vector instruction sets. To the artist this means that more iterations can be run in less time, making the work with fluids more intuitive and productive.
UP TO 12x SPEEDUP ON THE GPU
Yes, twelve times! 10 minutes instead of 2 hours. And there's a simple reason for that: today's high-end GPUs have 8-15 times the memory throughput of high-end CPUs. TurbulenceFD exploits that. It features a hybrid CPU/GPU simulation pipeline that achieves enormous speedups. Unlike some GPU based tools, this is not just a stripped down version of the CPU simulation. All features are supported at the same quality. When GPU memory is exceeded, TurbulenceFD switches back to the CPU on-the-fly. This allows you to achieve close to real-time speeds for low resolutions and scale smoothly to high resolutions in the hundreds of millions of voxels. Instead of carefully changing parameters, sending off the simulation job and not seeing the results for hours, fluid simulations can be tweaked in quick iterations with the artist observing the effect of the changes while the simulation is processing.
PHYSICALLY BASED FIRE SHADER
Getting the colors right is critical when creating believable fire animations. You can design your color gradients manually for full artistic control. If you want realistic fire colors, the process of tweaking the colors directly can be time consuming and tedious, though. So the fire shader simulates realistic high dynamic range fire colors based on the Black Body Radiation model. This model is controlled by only two temperature values. It generates the colors real fire would have at these temperatures. But TurbulenceFD doesn't stop you there. You may want realistic colors, but need more flexibility to tweak the enormous dynamic range that fire has. Maybe give the reds a boost, compress the dynamic range a little, or just use the generated colors as a starting point to edit the directly again.
In a nutshell, Multiple Scattering is Global Illumination for smoke. It's a way to light smoke more realistically and brighter, since it's illuminated from all directions. It also allows fire to illuminate smoke from the inside, which is essential for realistic shading of explosions. Unlike many Global Illumination techniques, Multiple Scattering in TurbulenceFD does not add noise and thus works well with for animation. And Multiple Scattering render times in TurbulenceFD are actually affordable. But if you're in a hurry you can still dial in a compromise between speed and illumination detail.
The heart of fluid dynamics is the creation of a sequence of velocity fields that describe the complex, characteristic motion of the fluid. You can use TurbulenceFD's velocity caches to control the movement of particle systems. This allows you to complement the voxel renderer with debris or sparks or just render the particles by themselves.
TurbulenceFD constantly tries to minimize the volume that needs to be processed in order to save memory and time. The velocity field is analyzed to make sure only those parts of the volume will be clipped that will not affect the flow in subsequent frames. If necessary you can control the sensitivity of the clipping for each fluid channel.
Emitters are to fluid simulation what brushes are to painting. If an object is set on fire, it emits heat and a flame. TurbulenceFD lets you use any geometric object or particle system to emit into fluid channel
