【英文介绍】

?

RealFlow is a fluid and dynamics simulation tool for the 3D and visual effects industry, developed by Next Limit Technologies in Madrid, Spain. This stand-alone application can be used in conjunction with other 3D programs to simulate fluids, water surfaces, fluid-solid interactions, rigid bodies, soft bodies and meshes.

?

Features:

RIGID

This material type is used to simulate the behaviour of rigid, non-deformable bodies. Rigids are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

?

GRANULAR

RealFlow's granular solver allows you to simulate piles of sand, wet snow, trickling salt, icy flakes, and many other materials. Granulars are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

?

ELASTICS

This material type is used to simulate the behaviour of soft-bodies, jelly-like substances, and even cloth. Elastics are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

?

MULTI-PHYSICS

Create and combine different materials like liquids, granular substances, or rigid and elastic bodies under a single simulation engine. RealFlow's high-performance Dyverso technology is GPU-accelerated and gives you unmatched control over your simulations.

?

VISCOELASTIC

Viscoelastic materials are, for example, the choice for foamy or silicone-based materials, but also muscles, some jelly-like substances, or certain paints behave that way. Viscoelastic liquids are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

?

CARONTE

RealFlow's fully-featured, multi-threaded body dynamics engine is named“Caronte”. Rigid bodies feature fast and accurate collisions, and a natural behaviour. Soft bodies support plastic and elastic free form deformation – even with high-resolution meshes.

?

FLUID SURFACES

RealWave meshes can be influenced and deformed through objects, particles, and many – freely combinable – wave generators for highly-realistic ocean surfaces. Other features are the export of displacement maps, creation of crest splashes, support of custom geometry, and the simulation of floating bodies with downstream forces.

?

TEXT TOOLS, OBJECTS

An editor lets you create text elements and use them in simulations. RealFlow's objects can be turned into rigid, elastic, or soft bodies; they also act as containers or obstacles for liquid simulations. Splines are created inside RealFlow or imported as SVG files, e.g. for particle emission or custom forces..

?

EXTERNAL FORCES

Forces are introduced through easy-to-use daemons. Many forces can be scaled, bounded, and limited to control their scope and behaviour. Examples for daemons are gravity, attraction, wind, vortices, drag, or spline-based forces. It also possible to introduce custom forces through Python, C++, and Graphs – RealFlow's node-based programming system.

?

RENDER

Easy steps to import your scene, add the fluids and render them out from RealFlow. Valid for still frames or animation sequences. Powered by the most advanced physically-based render engine: Maxwell Render.

?

MESHES

RealFlow's mesh engines are fast, and support particle- and grid-based fluids. The meshes store data like age or velocity, and they can be refined through filters. Clipping and polygon optimization is available, as well as various industry-standard formats for data exchange. Grid fluid meshes can be enhanced through displacement maps.

?

SHAPING TOOLS

RealFlow has tools for the creation of crown splashes and the filling of holes in particle fluid simulations. The latter one cares for thin, cohesive sheets of fluid and supports the forming of tendril structures.

?

INDUSTRY-STANDARD FILE

RealFlow is capable of reading and writing Alembic files with particles and geometry. An integrated stitching tool combines individual Alembic files from sequences to a single file. Furthermore, RealFlow reads and writes OpenVDB and Field3D files with volumetric data.

?

NETWORK SIMULATIONS

RealFlow uses“Independent Domains of Computation” (IDOCs) to distribute simulations over a network. Separate “Job Manager”and“Job Node”applications help to manage and organize simulations. An open C++ plugin architecture makes it possible to customize the process of sending projects to the manager. The simulation progress can be monitored with every web browser or a built-in panel.

?

PROGRAMMING INTERFACES

Programming made easier. In RealFlow's“Graphs”system, programs are created by connecting nodes with pre-defined functions, and help to accomplish almost any task, e.g. fast manipulation of fields, spatial viscosity, custom forces, or image processing. RealFlow offers interfaces to Python 2.7 and C++.
