edge_alias_energy — 3D render op

• Data kinds: image2d → measurement

• Call: import render_ssaa; render_ssaa.edge_alias_energy(img) -> 'float' (or ops3d.get("edge_alias_energy"))

Usage

The aliasing (jaggy) energy of edges = the RMS of the Laplacian (smaller is smoother).

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• render_beauty — py -3.11 examples_3d/render_beauty.py

• render_ssaa — py -3.11 examples_3d/render_ssaa.py
