tonemap_reinhard — 3D render op

• Data kinds: image2d → image2d

• Call: import render_tonemap; render_tonemap.tonemap_reinhard(hdr, exposure: 'float' = 1.0, white: 'float | None' = None) -> 'np.ndarray' (or ops3d.get("tonemap_reinhard"))

Usage

Compress HDR into `[0, 1]` LDR with Reinhard tone mapping. → float64, the same shape as the input.

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_tonemap — py -3.11 examples_3d/render_tonemap.py

Ops the type connects to (they accept image2d as input)
