Original anaglyph stereo study

Saved rendering runtime
Blender 5.2.3 LTS Release Candidate build fab76e95306d
Cycles CPU 32 samples with denoising Standard view transform
Native geometry and lighting no AI generation or paid inference

Render the original geometry into a NEW output directory
blender --background --factory-startup --python build-anaglyph-scene.py -- /absolute/new-study
The builder writes both PNGs camera JSON landmark CSV and original BLEND
Camera projected origins are checked against the stated pinhole formula
A fresh render on another Blender build or platform may differ in pixels
The original saved PNG pair is the reference for exact channel reproduction

Reproduce combination assets
Place build-anaglyph-assets.ts and anaglyph-study.ts beside each other
Install sharp 0.34.5 in that isolated script directory using bun add sharp@0.34.5
Use Bun 1.3.11 and supply a directory containing anaglyph-left.png and anaglyph-right.png
bun build-anaglyph-assets.ts /absolute/new-study
This writes default swapped and alpha PNGs JSON CSV and original WEBP illustrations

Independently verify outputs
uv run --no-project --with numpy --with pillow python verify-anaglyph-native.py /absolute/new-study
Copy the published anaglyph-camera-study.json into that directory when reproducing from the saved pair
The verifier checks all RGBA channels and sums in default swapped and alpha outputs
The verifier also checks the three projected origins not all surface disparities

Scope
Red from left and green plus blue from right by default
Swap reverses the input assignment without geometric alignment
Each decoded input is flattened onto white in byte space with integer rounding
Output is opaque no color correction matrix grayscale conversion resizing or cropping
No recovered depth auto rectification or calibrated glasses simulation
No claim of viewing comfort universal color fidelity or AI model inference
