RealFlow是Next Limit公司出品的流体动力学模拟软件。目前正被广泛的应用。只要使用过的人都知道其效果如何。并且该软件正在不断进行改进，内嵌脚本也越来越强大。4.2.3.0102版本说明如下（来不及翻译了。呵呵！看起来修正和改进可是不少啊）：
介绍
　　　　RealFlow是什么？
在我们了解RealFlow 3最新特性之前，先讨论一下RealFlow究竟是什么。Next Limit的RealFlow是一款独立的模拟软件，可以计算真实世界中运动物体的运动，包括液体。RealFlow提供给艺术家们一系列精心设计的工具，如流体模拟（液体和气体）、网格生成器、带有约束的刚体动力学、弹性、控制流体行为的工作平台和波动、浮力（以前在RealWave中具有浮力功能）。你可以将几何体或场景导入RealFlow来设置流体模拟。在模拟和调节完成后，将粒子或网格物体从RealFlow导出到其他主流3D软件中进行照明和渲染。对于支持的3D软件，可以看本文的总结部分。
与传统认知不同，RealFlow不是一个插件。插件（可以从 nextlimit网站免费下载）用来将模拟和几何体导入和导出，但是RealFlow则是一款独立的软件。RealFlow没有提供任何照明和渲染功能。你可以通过调节粒子流的UV坐标来拖拉纹理，从而创建各种纹理效果。你可以为网格创建UV坐标，并且创建“Wet Texture Maps” （打湿纹理贴图）。它可以创建非常丰富和真实的纹理效果，但不能在传统的场景中进行纹理贴图。
通过为软件重写流体解决方案，现在的模拟速度提高了20%到30%。程序可以更好地处理多处理器系统和巨大的内存分配。
最新的曲线和表达式编辑器让用户可以更加自由地调节关键帧。可以对基于表达式的条件产生“回应”，这是一个重要的改进，特别是对效果制作有明显的好处。这些主要特性也可以被整合到RealWave特性设置中。由于允许你进行某些操作，例如从一个基于表面属性的Real Wave表面上发射粒子。Real Wave具有产生波动和在几何体或粒子周围产生浮力效果的功能。
最具创新性的功能是“Wet Texture Maps”（打湿纹理贴图）。当粒子碰到表面，它在物体的表面上“绘制”纹理。因此，它可以在表面上留下痕迹或者“打湿”纹理。
Next Limit公司的工作人员将这款强大的软件提供给人们，使用RealFlow 4可以创建出易于控制并且非常真实的高级流体模拟效果。RealFlow 4带给我们很多最新特性，在稳定性和速度方面都有很大提高。大部分用户都认为最新的版本比旧版提供了更有趣更具意义的操作性能。你可以通过观看CG电影“I Robots”（机器人）来领略RealFlow制作出的优秀效果。
　RealFlow专用于水面波浪的模拟，如海面、落入物体后水面泛起的涟漪、行驶在水中的船(包括破浪泛起的粒子水花和产生的水面拖尾)，能够完成的项目包括：物体落入水面后激起波浪，并且随水面上下波动，还能产生溅起的水花。粒子落在水面上泛起的涟漪。在水面上快速运动的物体产生尾迹、水花和波浪，常用于船只的航行模拟。表现动态、自然波动的水面，如湖泊、水池、海洋等，还能产生海水拍岸溅起海浪水花的效果。
RealFlow是PC机上最好的流体动力学模拟软件。
RealFlow是目前解决流体动力模拟的一套比较完全的解决方案。RF是两个独立运行的软件，通过插件再与动画制作软件相连，如MAX、MAYA等。
RF制作思路是通过粒子模拟液体（气体等）的流动与碰撞，运算出正确的运动轨迹，再以质点与质点间产生平滑的多边形网格。保存序列文件后在3D软件中，如MAX中引入网格，从而达到完美的流体动画制作！RF可实现多种液体混合动画效果（水与牛奶）[E维]
1 RealFlow的用途
RealFlow是一种建立在流体动态计算技术上的物理粒子系统，它作为Windows NT/2000/XP下独立运行的程序直观的的实时OpenGL技术显示，可以很好的与3D软件相连接。如3ds max；Maya；LightWave3D；和Softimage。[E维]
3das max的自身粒子系统中很难表现真实流体动画，但我们只要有了RealFlow就可以很容易的实现飞溅的流体；黏液；气体等。
RealFlow有着十分友好的界面，如果我们是3ds max用户的话，那么就可以就可以在很短的时间掌握RealFlow这款顶级的流体插件。

2.- Features added or modified
------------------------------
- New scripting function "export" for the "Object" class.
- The collision for rigid bodies with "Mesh" collision primitive has been improved. In
some scenes this improvement makes the simulation 3 times faster than before.
- Constrainst are not displayed during play back.
- Object primitives can be cloned.
- Array tool can be applied to object primitives.
- Imported objects (SD files not included) can be cloned.
- The parameter "Create Wave" in the "RW Particle Interaction" panel has been removed.
Particles will create waves in the RealWave surface when the emitter is linked to the
RealWave node. To stop creating waves just remove the link.
- The interaction between fluids and rigid bodies has been improved. The interaction
is more physically correct than before and some artifacts regarding explosions of
energy either in the particles or in the bodies are gone.
- The computation of collisions between particles and objects has been threaded.
Scenes with a heavy load of particles in collision will benefit of this feature.
- New scripting function "setUV" for the "Particle" class.
- New scripting class "GUIFilePickerDialog" to show a file dialog browser.
- New scripting function "paint" for the "Scene" class. This will update the scene
views with the current state of the nodes.
- The vorticity of the particles is not computed by default as it used to. It seems
that most of the time this property is not needed so it isn't worth to spend time
computing it. Now if you want to have this property computed you have to enable
the "Compute Vorticity" parameter in the "Particles" panel. In the case that you
already have simulated a scene and afterwards you realize that you need vorticity you
can run the system script "Compute Vorticity" that is in you system scripts tool bar.
This avoid the fact of doing the whole simulation again just to get vorticity computed.
- A new system script has been added that converts a sequence of Maya PDC format
files into RealFlow BIN format files.
- By default the "animation(.sd)" export option for objects is checked. This way, the
simulation "Cache" mode for objects works by default.
- When the "Rope" constraint has a parent the visual line showing the rope connection
is updated as soon as the child or the parent change their positions.
- The "Rope" constraint can be manipulated just moving the parent or the children or
both.
- General improvements in the behaviour of the constraints.
- New scripting function "getParameterType" for the "Emitter" class.
- New scripting function "getParameterType" for the "Daemon" class.
- New scripting function "getParameterType" for the "Object" class.
- New scripting function "getParameterType" for the "Mesh" class.
- New scripting function "getParameterType" for the "Constraint" class.
- New scripting function "getParameterType" for the "Camera" class.
- New scripting function "getParameterType" for the "RealWave" class.
3.- Limitations
---------------
- Limitation #1
Undo/Redo doesn't work in the curve editor.
- Limitation #2
Switching Hypermesh from "No" to "Yes" casues the RW surface to grow.
- Limitation #3
Clone option only works with some type of nodes.
- Limitation #4
References to removed nodes are not retrieved when we "undo" the remove command. For
example the "Parent to" parameter.
- Limitation #5
Center selected is not working with all node types.
- Limitation #6
RealWave particle layer is not loaded at play time so it is difficult to make a mesh
including those particles at play time. To workaround this we recommend to create a
BinaryLoader with the particles from the particle layer and use this as a source for
mesh creation at play time.
- Limitation #7
When a SD file which is part of a scene is not found during the scene loading process and
the browse action for looking for a replacement is skipped the rest of nodes of the
scene are not loaded.
