Modo development is based-on an internally developed architecture called Nexus® that provides a consistent and malleable foundation for building products. Nexus is a highly-layered, cross-platform, generalized, time-aware architecture for rapid development of both 2D and 3D media applications. Foundry actively licenses the Nexus technology to third-party companies, including Dassault Systèmes SOLIDWORKS Corp. and Bentley Systems, who use it to deliver rendering and animation capabilities for their customers.
At the center of the Modo SDK is Nexus. It has a set of core functionality and systems with specific features and options arranged like spokes around the Nexus core. This extensible set of features are called servers, and are implemented as plug-ins.
