Use when making test pattern images or datasets for tonemap, gamut, LUT, PsychoV, RenoDRT, HDR, or cICP validation.\"\nargument-hint: \"pattern type, source gamut/transfer, nits or linear range, dimensions, output format, and validation target\"\n---\n\n# HDR Test Pattern Generation\n\nUse this small skill for **creating source patterns and synthetic datasets**. Larger skills should reference it instead of embedding pattern design rules.\n\n## Boundaries\n\n- Focus on generating deterministic test inputs: ramps, sweeps, charts, masks, and diagnostic images.\n- Use `analysis-graphing` for plots of pattern statistics or transform curves.\n- Use `bt2020-png-generation` when the final deliverable is a BT.2020 PQ RGB16 PNG with `cICP` or HDR ICC metadata.\n- Keep one-off experiments in a scratch output path; promote repeated generators or durable fixtures to `tools/analysis/` or the relevant test asset folder.\n- Do not silently reuse an existing image if the task needs a controlled source domain; document the source gamut, transfer, white point, and value units.\n\n## First classify the pattern goal\n\nBefore generating pixels, state what the pattern is intended to expose:\n\n- Tone-map shape, shoulder, toe, mid-gray, or diffuse-white behavior.\n- Gamut mapping, hue preservation, negative-channel clipping, or out-of-gamut handling.\n- LUT precision, tetrahedral/trilinear interpolation, or banding.\n- PQ/HLG/SDR transfer correctness and viewer metadata behavior.\n- Spatial artifacts: edge halos, checkerboard instability, bloom thresholds, sharpening, or temporal reprojection.\n- Scalar/energy maps for RenoDRT/PsychoV/N2 reapply experiments.\n\n## Source domain checklist\n\nEvery pattern needs explicit metadata in the script, filename, or sidecar stats:\n\n| Field | Examples |\n|---|---|\n| Gamut / primaries | BT.709, BT.2020, AP1, AP0 |\n| White point | D65, D60, adapted D60→D65 |\n| Transfer | scene-linear, display-linear nits, sRGB, PQ |\n| Value scale | `0..1`, stops around 1.0, absolute nits, diffuse-white-relative |\n| Bit depth / format | EXR float, RGB16 PNG, 8-bit preview PNG/WebP |\n| Clipping policy | preserve negatives for stats, clip only at output, hard clip to gamut, mask out-of-gamut |\n\nDo not normalize pattern maxima unless normalization is the experiment.\n\n## Useful pattern families\n\n| Pattern | Use for | Notes |\n|---|---|---|\n| Neutral ramp / step wedge | Tone curves, PQ quantization, banding | Include fine ramp plus labeled stops or nits steps. |\n| Hue sweep | Gamut compression and hue preservation | Sweep hue in a known gamut; keep saturation/value and luminance assumptions explicit. |\n| Primary/secondary chips | BT.709/BT.2020/AP1 comparison | Include white/gray references and expected out-of-gamut chips. |\n| OOG stress chart | Negative channels, over-1 values, matrix/adaptation errors | Preserve unclipped stats before output clipping. |\n| Banding panel | 8-bit/10-bit/16-bit path checks | Use smooth ramps plus small-amplitude perturbations when needed. |\n| Checker/edge pattern | Spatial filters, bloom, sharpening, TAA artifacts | Include hard edges and subpixel-aligned variants if relevant. |\n| Synthetic scene chart | End-to-end tone/gamut validation | Keep source EXR and rendered outputs together. |\n| Scalar/energy map | N2/RenoDRT/PsychoV energy diagnostics | Replicate to RGB only at the final visualization/export step. |\n\n## Output guidance\n\n- Prefer EXR float for source fixtures that must preserve scene-linear or out-of-range values.\n- Use ordinary SDR PNG only for quick human previews or SDR-specific tests.\n- Use BT.2020 PQ RGB16 PNG plus `cICP` only for HDR delivery or viewer-signaling tests.\n- Keep stats beside generated outputs: min/max, nonfinite count, negative channels, over-range channels, chosen nits mapping, and source domain.\n- Name files with the important domain choices, for example `bt709_linear_hue_sweep`, `bt2020_hdr_pq_100nits`, or `syntheticChart_rec709_finite`.\n\n## Existing references\n\n- [HDR pattern template](./templates/hdr_pattern_template.py) for deterministic ramps, hue sweeps, and sidecar stats.\n- `tests/D3D12HDR-test/images/syntheticChart_rec709.01.exr` for a recurring synthetic chart source.\n- `tests/D3D12HDR-test/images/RGB_sweep_smooth_31x50.exr` for RGB sweep validation.\n- `tools/analysis/synthetic_neutwo_energy_reapply_bt2020.py` for synthetic chart to BT.2020 HDR output workflow.\n- `tools/analysis/validate_mb_compress.py` for BT.2020 hue sweep validation patterns.\n- `tools/analysis/syntheticChart_rec709_finite/` for generated comparisons and stats.\n\n## Common mistakes to avoid\n\n- Do not mix BT.709, BT.2020, AP1, and AP0 values without naming the conversion path.\n- Do not apply sRGB transfer to data that is already linear or PQ.\n- Do not PQ-encode twice.\n- Do not clip negative or out-of-gamut values before recording diagnostics unless clipping is the behavior being tested.\n- Do not rely on screenshots as validation assets when exact pixels or metadata matter.\n- Do not create a new pattern generator when an existing source fixture or script already covers the same controlled case.\n","tagline":"RenoDX workflow for generating HDR/SDR test patterns, synthetic charts, ramps, gradients, hue sweeps, color bars, checkerboards, banding panels, gamut stress images, BT.709/BT.2020/AP1 comparisons, and scalar/energy-map validation sources.
