HI3D 3.0 (Twinkle3D): Object-specific 3D Asset Generation with High Resolution

Hi3D 3.0 is presented, an image-to-3D generation system targeting object-specific fidelity, with Twinkle3D as its geometry model for generating watertight triangle meshes at $2048^{3}$ resolution, with a fine-grained image-3D cross-modal interaction mechanism that strengthens correspondence between visual evidence and...

NIDAR: NIR-Guided Intrinsic Decomposition for Scalable Scene-Agnostic LiDAR Intensity Reconstruction

LiDAR return intensity provides complementary surface-response cues for robotic perception and state estimation, yet many simulation pipelines omit it or reproduce it using reconstruction methods that require real intensity supervision and per-scene optimization. These requirements increase data-collection and fitting...
