Lucida: Parse, Generate, and Place for Composable Real-to-Sim Scene Modeling
Minghan Qin, Yuang Wang, Xiuyu Yang +6
Composable scene modeling aims to recover a real indoor scene as complete, editable object assets arranged as observed, giving robot simulation and embodied AI a simulation-ready r…
aDSL: Agentic 3D Creation via Joint Agent-Program Design
Rui-Huan Wang, Si-Tong Wei, Jia-Qi He +3
Programmatic representations provide a compelling paradigm for 3D content creation, enabling fine-grained edits, interpretability, and explicit structural control. Yet, agentic wor…
BlockVLA: Accelerating Autoregressive VLA via Block Diffusion Finetuning
Ruiheng Wang, Shuanghao Bai, Haoran Zhang +2
While autoregressive (AR) Vision-Language-Action (VLA) models have demonstrated formidable reasoning capabilities in robotic tasks, their sequential decoding process often incurs h…
OctGPT: Octree-based Multiscale Autoregressive Models for 3D Shape Generation
Si-Tong Wei, Rui-Huan Wang, Chuan-Zhi Zhou +2
Autoregressive models have achieved remarkable success across various domains, yet their performance in 3D shape generation lags significantly behind that of diffusion models. In t…
