PAT3D: Physics-Augmented Text-to-3D Scene Generation

ICLR 2026poster

We introduce PAT3D, the first physics-augmented text-to-3D scene generation framework that integrates vision–language models with physics-based simulation to produce physically plausible, simulation-ready, and intersection-free 3D scenes. Given a text prompt, PAT3D generates 3D objects, infers their…

Generating Images with 3D Annotations Using Diffusion Models

ICLR 2024spotlight

Diffusion models have emerged as a powerful generative method, capable of producing stunning photo-realistic images from natural language descriptions. However, these models lack explicit control over the 3D structure in the generated images. Consequently, this hinders our ability to obtain detailed…

SemTrack: A Large-scale Dataset for Semantic Tracking in the Wild

ECCV 2024poster

"Knowing merely where the target is located is not sufficient for many real-life scenarios. In contrast, capturing rich details about the tracked target via its semantic trajectory, i.e. who/what this target is interacting with and when, where, and how they are interacting over time, is especially c…
