DynaTokens: Teaching Dynamics to Camera-Controlled Video Models at Test Time
Ziqi Ma, Ma Ziqi, Hongqiao Chen +3
Video generation must account for two sources of motion, one induced by the observer's camera path and the other caused by scene dynamics. An ideal camera-controlled video model sh…

Linear Mechanisms for Spatiotemporal Reasoning in Vision Language Models
Raphi Kang, Hongqiao Chen, Georgia Gkioxari +1
Spatio-temporal reasoning is a remarkable capability of Vision Language Models (VLMs), but the underlying mechanisms of such abilities remain largely opaque. We postulate that visu…

Feedforward 3D Editing via Text-Steerable Image-to-3D
Ziqi Ma, Hongqiao Chen, Yisong Yue +1
Recent progress in image-to-3D has opened up immense possibilities for design, AR/VR, and robotics. However, to use AI-generated 3D assets in real applications, a critical requirem…
