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.
