Holographic displays trade field of view against eyebox size because a spatial light modulator provides a fixed étendue. We pair a commercial 4-bit piston-mode phase light modulator (PLM) with a pixel-registered binary metasurface designed for an achromatic π phase step. Grouping the PLM into s×s superpixels while reta...
Real-world scenes are compositional: bricks, blades of grass, pebbles, and tree leaves recur across human-built and natural environments. Existing neural scene representations model these elements independently. Most 3D Gaussian Splatting and follow-up abstraction and compression methods treat each element as unique, f...

Latent world models based on Joint-Embedding Predictive Architecture (JEPA) are deterministic by design. While successful in fully observable scenarios, this paradigm breaks down when past observations and actions lead to multiple plausible future possibilities, e.g., due to occlusion. We introduce EpicWorldModel, a fr...
