render_shaded — 3D `render` op

• Data kinds: normalmap → image2d

• Call: import match3d; match3d.render_shaded(normals_img, light=(0, 0, 1), ambient=0.1) (or ops3d.get("render_shaded"))

Usage

Normal map (H,W,3) + light direction → a Lambertian shaded image (appearance-sample generation, the bridge to optics).

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.
