render_regolith — 3D `render` op

• Data kinds: mesh → rgbimage

• Call: import render_beauty; render_beauty.render_regolith(V, F, *, pose=None, intrinsics=None, size: 'int' = 512, ss: 'int' = 2, sun: 'Sequence[float]' = (0.3, 0.4, 1.0), w: 'float' = 0.42, g: 'float' = -0.35, B0: 'float' = 0.87, h: 'float' = 0.01, roughness_deg: 'float' = 26.0, sun_angular_diameter_deg: 'float' = 0.53, shadow_samples: 'int' = 4, ao_samples: 'int' = 32, tint: 'Sequence[float]' = (1.0, 0.97, 0.93), self_illumination: 'float' = 1.0, exposure='auto', albedo_variation: 'float' = 0.12, seed: 'int' = 0, smooth_normals: 'bool' = True, background: 'Sequence[float]' = (0.0, 0.0, 0.0), bump=None, vertex_normals=None, vertex_albedo=None, exposure_target: 'float' = 0.45) -> 'np.ndarray' (or ops3d.get("render_regolith"))

Usage

Render an asteroid's regolith physically based (Hapke + ray-cast shadows at the Sun's angular diameter + zero ambient) → RGB `(size,size,3)`.

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)

• itokawa_regolith_hero — py -3.11 examples_3d/itokawa_regolith_hero.py

Ops the type connects to (they accept `rgbimage` as input)
