[edit] Overview

These internal files are known as Swarm Binaries, because they are read and rendered by the Swarm VFX System originally developed by Andrew Willmott. Variants of this system are used not only The Sims 3, but also The Sims 2, The Sims 4, SimCity 4, SimCity 5, and Spore. Swarm Binaries are compiled from text files written in Arg Script language. More info can be found in presentations here: http://www.andrewwillmott.com/talks/swarm-procedural-content

The internal format for Swarm Binaries was derived primarily by analyzing internal code for parsing them, hidden within The Sims 3 main executable itself.

The field names were initially guessed at by playing around with their values and observing the changes to the effect in The Sims 3 itself, by using an effect playing debug object, and later by using a dedicated Effect Player which uses the game's engine API included with The Sims 3 Create-A-World Tool. The actual field names were finally found as symbols for Swarm Binary structures within PDB files included with leaked dev versions of SimCity 5, and correlated to corresponding fields in The Sims 3's Swarm Binary format, which is why some of the fields are still unknown.

Format Facts:

• It is primarily Big Endian, but groups of floats denoting vectors are swizzled to Little Endian.
• Curves are used to determine how the effects change over time.
• There are often "vary" and "offset" fields corresponding to this curves that are used to adjust the values using the following formula:

  random(1 - vary, 1 + vary) * current_value + offset

• The format can be easily expanded by increasing the version of a component type and/or adding entirely new components.

[edit] Format

All data is in Big Endian order unless otherwise noted(most floats). This spec is very primitive and needs work.
