• Abstract: Understanding and predicting the dynamics of the physical world can enhance a robot's ability to plan and interact effectively in complex environments. While recent video generation models have shown strong potential in modeling dynamic scenes, generating videos that are both temporally coherent and geometrically consistent across camera views remains a significant challenge. To address this, we propose a 4D video generation model that enforces multi-view 3D consistency of videos by supervising the model with cross-view pointmap alignment during training. This geometric supervision enables the model to learn a shared 3D representation of the scene, allowing it to predict future video sequences from novel viewpoints based solely on the given RGB-D observations, without requiring camera poses as inputs. Compared to existing baselines, our method produces more visually stable and spatially aligned predictions across multiple simulated and real-world robotic datasets. We further show that the predicted 4D videos can be used to recover robot end-effector trajectories using an off-the-shelf 6DoF pose tracker, supporting robust robot manipulation and generalization to novel camera viewpoints.

  We present a novel approach to the generation of static and articulated 3D assets that has a 3D autodecoder at its core.

We then identify the appropriate intermediate volumetric latent space, and introduce robust normalization and de-normalization operations.

  We propose a 3D video prediction (T3VIP) approach that explicitly models the 3D motion by decomposing a scene into its object parts. Our model is fully unsupervised, captures the nature of the real world, and the observational cues in image and point cloud domains constitute its learning signals. To the best of our knowledge, our model is the first generative model that provides an RGB-D video prediction of the future for a static camera.

We show our model generalizes well its predictions across varying number and appearances of interacting objects as well as across camera viewpoints.
