LEGO 3D Builds: 1,418 Sets with Multi-View Renders and Captions

egnch's LEGO 3D dataset contains 1,418 LEGO sets sourced from the LDraw Official Model Repository. Each set includes 4 rendered views, a colored point cloud with 10,000 points, and 10 English captions. The dataset was last updated on 2026-06-10.

Use Cases

• Train text-to-3D retrieval models based on the 10 captions per LEGO set.
• Develop 3D reconstruction algorithms using the provided 10,000-point colored point clouds.
• Benchmark multi-view 3D object recognition systems based on the 4 rendered views per set.
• Create multimodal datasets for aligning text descriptions with 3D visual data.

Strengths

• Contains 1,418 distinct LEGO sets, providing a substantial collection.
• Each set includes 4 rendered views at 512x512 resolution, 10 captions, and a 10,000-point point cloud, offering multiple data modalities.
