Omniverse Kit is a toolkit for building native Omniverse applications and microservices. It leverages a framework that provides a wide variety of functionality through a set of light-weight extensions. These stand-alone extensions are plugins authored in Python or C++. Kit is a flexible and extensible development platform for both Omniverse Apps and microservices. Run it with a UI, or headless to create a microservice. Use the UI engine to write an entirely customizable UI application. For better performance or to access C++ APIs, add lower-level C++ plugins to extensions and connect to the UI through binding. These extensions include the icons, images, and configuration they need to run individually.
