Winner of the CVPR 2026 OpenSUN3D Challenge

I collaborated with Chengkun (Charlie) Li on the winning submission for Track 2, Open-Vocabulary 3D Affordance Grounding, at the CVPR 2026 OpenSUN3D Challenge.

Challenge

The track evaluates whether a system can locate and segment the functional part of a 3D indoor scene that enables a language-described action. For example, given an instruction such as opening a refrigerator, the system must ground the request to the relevant interactive element, such as its handle, rather than only recognizing the refrigerator as an object.
