This branch is for the Omniverse Kit 106 BETA. It includes BETA versions of the Kit SDK, associated development tools, and templates. For the latest stable release, see the 105.1 branch.
Welcome to kit-app-template, an essential toolkit for developers diving into GPU-accelerated application development within the NVIDIA Omniverse ecosystem. This repository provides streamlined templates and tools designed to simplify the creation of high-performance OpenUSD-based applications powered by the Omniverse Kit SDK.
The Omniverse Kit SDK empowers developers to build immersive 3D applications with ease. Key features include:
- Language Support: Develop in Python or C++, offering flexibility and power to a wide range of developers.
- OpenUSD Foundation: Utilize Open Universal Scene Description (OpenUSD) for creating, manipulating, and rendering rich 3D content.
- GPU Acceleration: Leverage GPU-accelerated capabilities for high-fidelity visualization and simulation.
- Extensibility: Easily build specialized Extensions that provide dynamic user interfaces, integration with various systems, and provide direct control over OpenUSD data, making it versatile for numerous applications.
The kit-app-template enables developers to create cross-platform (Windows and Linux) accelerated applications, equipped with tooling to streamline packaging for easier deployment. This covers a broad range of use cases, from simulating real-world systems to generating photorealistic synthetic data for AI training. Whether your focus is on creating engaging virtual worlds, developing tools for data analysis, or crafting simulations, the combination of this repository and the Kit SDK provides the foundation you need.
The kit-app-template repository is designed to abstract complexity, jumpstarting your development with pre-configured templates, tools, and essential boilerplate. For those seeking a deeper understanding of the application and extension creation process, we've provided a companion tutorial. Explore the tutorial here—it offers detailed insights into the underlying structure and mechanisms, enabling a thorough grasp of both Kit and the development process.

This section guides you through creating your first Kit SDK-based Application using the kit-app-template repository. For a more comprehensive explanation of functionality previewed here, reference the following Tutorial for an in-depth exploration.
Begin by cloning the kit-app-template to your local workspace:
git clone https://github.com/NVIDIA-Omniverse/kit-app-template.gitcd kit-app-templateRun the following command to initiate the configuration wizard:
Linux:
./repo.sh template newWindows:
.\repo.bat template newNote: If this is your first time running the
template newtool, you'll be prompted to accept the Omniverse Licensing Terms.
Follow the prompt instructions:
- ? Select with arrow keys what you want to create: Application
- ? Select with arrow keys your desired template: Kit Base Editor
- ? Enter name of application .kit file [name-spaced, lowercase, alphanumeric]: [set application name]
- ? Enter application_display_name: [set application display name]
- ? Enter version:: [set application version]
Build your new application with the following command:
Linux:
./repo.sh buildWindows:
.\repo.bat buildIf you experience issues related to build, please see the Usage and Troubleshooting section for additional information.
Initiate your newly created application using:
Linux:
./repo.sh launchWindows:
.\repo.bat launch? Select with arrow keys which App would you like to launch: [Select the created editor application]
NOTE: The initial startup may take 5 to 8 minutes as shaders compile for the first time. After initial shader compilation, startup time will reduce dramatically
kit-app-template features an array of configurable templates for Extensions and Applications, catering to a range of desired development starting points from minimal to feature rich.
Begin constructing Omniverse Applications using these templates
-
Kit Service: The minimal definition of an Omniverse Kit Service Application. This template is useful for creating headless services leveraging Omniverse Kit functionality.
-
Kit Base Editor: A simple application for loading, manipulating and rendering OpenUSD content from a graphical interface.
-
USD Explorer: A full featured application for managing, collaborating on, and exploring large Open USD scenes.
Enhance Omniverse capabilities with extension templates:
-
Basic Python: The minimal definition of an Omniverse Python Extension.
-
Basic C++: The minimal definition of an Omniverse C++ Extension.
-
Python UI: An extension that provides an easily extendable Python-based user interface.
The kit-app-template includes a suite of tools to aid in the development, testing, and deployment of your projects. A brief overview of some key tools:
-
Help (
./repo.sh -hor.\repo.bat -h): Provides a list of available tools and their descriptions. -
Template Creation (
./repo.sh templateor.\repo.bat template): Assists in starting a new project by generating a scaffold from a template application or extension. -
Build (
./repo.sh buildor.\repo.bat build): Compiles your applications and extensions, preparing them for launch. -
Launch (
./repo.sh launchor.\repo.bat launch): Starts your compiled application or extension. -
