blender-cli-rendering

A set of Blender Python scripts for generating scenes and rendering images directly from command-line interface.

Principles

Able to run without display (thus, the renderer should be Cycles instead of EEVEE)
Support the latest LTS release (currently 2.93)

Possible Usages

Material to learn how to use Blender Python APIs.
Visualization of 3D data with fancy rendering quality.
Generation of synthetic training datasets for machine learning-based computer vision.
