An emitter’s particles can be stored in different file and data formats for further use. The standard format is called "BIN" and stores a complete set of position and physical data. Other formats, such as PD, allow the user to store specific information, for example density or pressure. A very convenient and straightforward method to export particle data comes with the new Alembic format. This file type allows you to export selected data channels, has a hierarchical approach and is supported by many 3D applications. You can find out more about RealFlow’s export options with standard emitters and the Alembic format under “Export Central”. The stored BIN files are normally used to create a polygon mesh inside RealFlow representing the three dimensional volume of the fluid. This mesh finally becomes shaded in your 3D application to render the fluid. Additionally it is also possible to continue processing the particles to create foam or spray.

Particle fluids and fluid meshes can be previewed directly inside RealFlow with the new “Maxwell Interactive” render engine – completely shaded and with specific material properties, e.g. honey or water. This unique feature gives you the possibility to render a photorealistic preview of your fluids, either as a mesh (this option requires a mesh, of course) or as a particle cloud. One of the main advantages is that “Maxwell Interactive” is even capable of adding particles at render time to get a much denser fluid and, as a consequence, a better and more realistic preview. This method is exactly the same you can find in “Maxwell Studio” and the RFRK, there it is called “MultiPoint”. “MultiPoint” has a procedural approach to add millions of particles in a very short time. The result is an absolutely realistic impression of spray or misty particle clouds. Please bear in mind that these extra particles are not stored, but only temporarily created. After the render process, the “MultiPoint” particles are lost. This guarantees that the original fluid simulation will not be modified.

Regardless of the method you use, you will always find a set of 14 emitter types for any field of application. Of course, RealFlow standard emitter nodes are also supported by the “Relationship Editor”. In RealFlow 2013, this editor has substituted the “Global Links” and “Exclusive Links” panels and now you can establish all interactions visually with node icons and connections between them.
