Generating Physically Stable and Buildable Brick Structures from Text

ICCV 2025poster

We introduce BrickGPT, the first approach for generating physically stable interconnecting brick assembly models from text prompts. To achieve this, we construct a large-scale, physically stable dataset of brick structures, along with their associated captions, and train an autoregressive large lang…

Neural Lighting Simulation for Urban Scenes

NeurIPS 2023poster

Different outdoor illumination conditions drastically alter the appearance of urban scenes, and they can harm the performance of image-based robot perception systems if not seen during training. Camera simulation provides a cost-effective solution to create a large dataset of images captured under d…

AdvSim: Generating Safety-Critical Scenarios for Self-Driving Vehicles

CVPR 2021poster

As self-driving systems become better, simulating scenarios where the autonomy stack may fail becomes more important. Traditionally, those scenarios are generated for a few scenes with respect to the planning module that takes ground-truth actor states as input. This does not scale and cannot identi…
