blendersynth

BlenderSynth is a Python library for generating large scale synthetic datasets using Blender. Compared to other tools, BlenderSynth provides support for: Custom Shader AOVs to render rich per-pixel information; node control; multithreading support; and multiview rendering support.

Usage

See documentation for installation, debugging/troubleshooting and examples.

BlenderSynth supports Blender 3 and 4.

Contributions and Projects

This project is currently in Beta. Please let me know what new features you would like, or feel free to make a pull request! BlenderSynth has been used in projects such as:

FOUND and FOCUS - Synthetic foot datasets for 3D reconstruction.
Sim4D - Synthetic data for 4D Slam.

If you use BlenderSynth for a project, please contact me about it - I might include it in the documentation as a usage example!
