Static 3D Spatial Reasoning
The ability of a model to understand and make judgments about a three-dimensional scene at a single moment in time, including inferring object position, orientation, size and spatial relationships from images. Common tasks include 3D visual grounding, spatial question answering and scene layout prediction.

There is a pronounced "spatial–dynamic interference" phenomenon between static 3D spatial understanding and dynamic 4D scene reasoning: post-training on 3D tasks weakens a model's ability to understand dynamic scenes, while models specialized in 4D reasoning often lack a solid foundation in static 3D spatial reasoning.
Static 3D spatial reasoning refers to a model's understanding and judgment of a three-dimensional scene at a single moment, with common tasks including 3D visual grounding, spatial question answering and scene layout prediction.
DynThinker demonstrates that static 3D and dynamic 4D capabilities can simultaneously reach leading levels in the same model, rather than necessarily trading one for the other.
