Atoms Crowd is framework designed for crowd simulations for the visual effects and animation industries. Atoms is completely standalone tool that can easily be integrated into any 3D application and supports integration Autodesk Maya and Side FX Houdini. The framework allows for an easy change of data between the two 3D programs.

Atoms sets the focus of making crowd simulation easy no matter your skill level. The idea is that you don’t need to be a technical artist or savvy with scripting to art direct crowd shots. The “democratization” of crowd simulation and other technically heavy effects sims has been an ongoing one. Others have brought simplicity into focus with products like Golaem Crowd for Maya.

Atoms is different from the others by being a standalone framework allowing it to support multiple 3D software packages. The framework gives you full control on every aspect of the simulation process. Different users can take advantage of their own skillsets: Like working with nodes, python scripting, or plugins — Each can be an Atoms workflow
