Evidencepartial
We introduce LivingWorld, an interactive framework for generating 4D worlds with environmental dynamics from a single image.
Implicationpartial
Explicitly stated in the abstract as the core contribution of the paper.
Verificationpartial
partial
Evidencepartial
LivingWorld addresses this challenge by progressively constructing a globally coherent motion field as the scene expands.
Implicationpartial
Directly stated as the addressed challenge and solution in the abstract.
Verificationpartial
partial
Evidencepartial
We further represent motion using a compact hash-based motion field, enabling efficient querying and stable propagation of dynamics throughout the scene.
Implicationpartial
Explicitly stated as a novel technical component of the method.

Evidencepartial
We further represent motion using a compact hash-based motion field, enabling efficient querying and stable propagation of dynamics throughout the scene.
Implicationpartial
Directly stated as a key technical representation in the abstract.
Verificationpartial
partial
Evidencepartial
This representation also supports bidirectional motion propagation during rendering, producing long and temporally coherent 4D sequences without relying on expensive video-based refinement.
Implicationpartial
Directly stated as a capability and benefit of the representation, though 'expensive' is a qualitative term.
Verificationpartial
partial
Evidencepartial
On a single RTX 5090 GPU, generating each new scene expansion step requires 9 seconds, followed by 3 seconds for motion alignment and motion field updates, enabling interactive 4D world generation with globally coherent environmental dynamics.
Implicationpartial
Explicitly stated with clear numeric performance metrics.
Verificationpartial
partial
Evidencepartial
enabling interactive 4D world generation with globally coherent environmental dynamics.
Implicationpartial
Directly stated as an outcome enabled by the performance metrics, though 'interactive' is a qualitative claim supported by the timing results.
Verificationpartial
partial
Evidencepartial
While recent advances in 3D scene generation enable large-scale environment creation, most approaches focus primarily on reconstructing static geometry, leaving scene-scale environmental dynamics such as clouds, water, or smoke largely unexplored.
Implicationpartial
Directly stated as a limitation of prior work, establishing the paper's motivation.
Verificationpartial
