RealFlow's “Spreadsheet” is a powerful analysis tool for a scene's simulation elements and nodes.

With “Spreadsheets” you are able to gather information about every individual particle, vertex, polygon, but also about objects, meshes, and other nodes. User-definable rules will also help you to filter and separate your simulation elements visually. It is, for example, possible to show only particles with a certain vorticity or density and mark them with colours. With objects and meshes you will receive data about their vertices and polygons. Rigid or soft body show properties like velocity. This information helps you to analyse your scene, spot problems, and predict the simulation nodes' behaviour.

All this data can be edited and changed. Furthermore it is possible to apply your changes – even on a per-particle or per-vertex basis.

It is also possible to preview the → “Filter” daemon's output, open multiple “Spreadsheet” panels for side-by-side comparisons, and check a node's memory consumption. There are two ways of opening the “Spreadsheets” panel:

  • Layout > Spreadsheet

  • Nodes > right-click on a node > Spreadsheet

You do not have to close “Spreadsheet” during simulation, but the values are not updated in realtime: new values appear when the simulation is stopped.

Layout

The "Spreadsheet" layout consists of several sections (the entries are just an example):

 

 

Jump to

Source (A)

The drop-down menu provides a list with the scene's nodes – the active node is displayed. When you select a different node the displayed information will change accordingly.

Detail - Filter entries (B)

This section is the "Spreadsheet" engine's core and allows you the creation of → custom filter rules to focus on specific aspects of a node, e.g.

  • particles with a certain velocity
  • rigid bodies with a mass value greater than a given threshold
  • polygons with an area smaller than a given threshold
  • and so on.

Detail - Spreadsheet Table (C)

The → "Detail" area's spreadsheet table has exactly the same structure for all node elements. Although every node type has its own "Spreadsheet", some of them do not contain any information, e.g. IDOCs, most of RealFlow's daemons, or cameras.

Summary (D)

The → "Summary" area is exactly the same for all node types, but the displayed information varies. Some node types (e.g. IDOCs and cameras) do not provide any information.

Checkboxes and Buttons (E)

This layout part is the same for all node types. The available features are explained in the → "Spreadsheet - Detail" and → "Spreadsheet - Summary" sections.
