And Multiple Scattering render times in TurbulenceFD are actually affordable. Unlike many Global Illumination techniques, Multiple Scattering in TurbulenceFD does not add noise and thus works well with for animation. It also allows fire to illuminate smoke from the inside, which is essential for realistic shading of explosions. It’s a way to light smoke more realistically and brighter, since it’s illuminated from all directions.
In a nutshell, Multiple Scattering is Global Illumination for smoke. 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. 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. To the artist this means that more iterations can be run in less time, making the work with fluids more intuitive and productive. And implementing this pipeline using the latest High Performance Computing technology to optimally exploit Memory Caches, Multi-Core CPUs and advanced vector instruction sets. This includes a careful selection of efficient numerical methods that provide high accuracy and stability throughout the simulation pipeline. That is why TurbulenceFD’s simulation pipeline has been designed from the ground up to optimize performance. The biggest technological challenge in fluid simulation is the handling of the large amounts of data that a sequence of voxel grids requires.
This simulation process produces a voxel grid for each frame, which is cached on disk for use by the Volumetric Renderer. 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. 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. TurbulenceFD’s simulation pipeline implements a voxel-based solver based on the incompressible Navier Stokes equations. It’s compatible with 64bit CINEMA 4D Prime, Broadcast, Visualize or Studio, R12 or newer. Simulate fire, smoke, dust and other gaseous phenomena.
TFD is designed to be easy to use, optimized for performance and produce very high quality results. Turbulence Fluid Dynamics (TFD) makes physical simulations of fire, smoke, dust and other gaseous phenomena available directly in CINEMA 4D. Jawset TurbulenceFD for CINEMA 4D R18/R17/R16 Latest v1.
