HiFi-BRep: High-Fidelity Latent Representation for Robust B-Rep Generation
Junhao Hou, Chenqi Luo, Pufan Wang +5
Boundary representation (B-Rep) generation is a fundamental task in computer-aided design, yet the direct synthesis of high-fidelity and structurally valid B-Reps remains a major c…
JARVIS: A Just-in-Time Augmented Reality VLM-Powered Instruction System for Cross-Reality Task Guidance
Yusi Sun, Ying Jiang, Jiayin Lu +3
Many everyday tasks rely on external tutorials such as manuals and videos, requiring users to constantly switch between reading instructions and performing actions, which disrupts…
VoroLight: Learning Voronoi Surface Meshes via Sphere Intersection
Jiayin Lu, Ying Jiang, Yumeng He +2
Voronoi diagrams naturally produce convex, watertight, and topologically consistent cells, making them an appealing representation for 3D shape reconstruction. However, standard di…
SeeClear: Reliable Transparent Object Depth Estimation via Generative Opacification
Xiaoying Wang, Yumeng He, Jingkai Shi +4
Monocular depth estimation remains challenging for transparent objects, where refraction and transmission are difficult to model and break the appearance assumptions used by depth…
Recent Advances in Metallic Glasses
Silvia Bonfanti, Ralf Busch, Jesper Byggmästar +12
This paper reviews recent advances in the field of metallic glasses, focusing on the development of novel experimental techniques and in silico models. We discuss progress in exper…
SPARK: Sim-ready Part-level Articulated Reconstruction with VLM Knowledge
Yumeng He, Ying Jiang, Jiayin Lu +2
Articulated 3D objects are critical for embodied AI, robotics, and interactive scene understanding, yet creating simulation-ready assets remains labor-intensive and requires expert…
