Spot¶

This basic example displays a surface mesh with its polygon edges overlaid as a wireframe.

Data¶

The quadrangulated Spot model is by Keenan Crane and is released into the public domain.

Input contract¶

Reproduce and inspect¶

python ../render_gallery.py --check Spot
python ../render_gallery.py --artifacts Spot
