ILLIXR v4.2 Released

ILLIXR v4.2 is out! 

A new release of ILLIXR significantly expands platform support and integrates first-of-their-kind capabilities for XR –

• Expanded platform support: This release is a major expansion of ILLIXR’s platform support, bringing native Windows and Android support alongside Linux. It provides unified support for offloading a wide range of capabilities to the edge or cloud from Android hardware, including Meta Quest 3. Collaboration with Project Agora, led by Brighten Godfrey.

• SemanticXR [ISMAR 2026 / TVCG]: This brings real-time, low-power semantic mapping and querying with a distributed device-cloud architecture to XR. A demo on Meta Quest 3 lets the user ask for an object. SemanticXR highlights the object directly in the user's physical environment and guides the user to it —even when the object is no longer in view. This is a collaboration with NVIDIA and the core of SemanticXR is also available in a branch of NVIDIA’s XR AI. The paper appears in TVCG'26 (selected papers from ISMAR'26). 
  

• Boba [ECCV 2026]: This brings efficient, power-aware single-instance execution and scalable batched simulation of physics-based Gaussian digital twins for XR and robotics. With a demo on Meta Quest 3, you can interact with deformable digital twins inside immersive 3D scenes. This is a collaboration with Meta Reality Labs and led by Shenlong Wang. The  paper appears in ECCV'26 and more details on the project are here.
