ShapeNetCore: Densely Annotated 3D Object Models

51,300 unique 3D models across 55 common object categories. Each model is linked to a WordNet 3.0 synset, providing a structured semantic hierarchy for the 3D geometry.

Use Cases

• Train 3D shape classifiers using the 55 object category labels
• Perform semantic search and retrieval using WordNet 3.0 synset mappings
• Evaluate 3D generative models against the 51,300 unique model meshes

Strengths

• 51,300 unique 3D models
• 55 common object categories
• Direct linkage to WordNet 3.0 synsets for semantic grounding
