Image Pipeline

Build one causal image graph: one HDR scene pass with depth, selected shared signals, and one final output conversion. Add a scene traversal or attachment only when its measured alternative is worse.

Use the atomic owner for each admitted effect:

• $threejs-ambient-contact-shading for GTAO and indirect-light composition;
• $threejs-bloom for glare source selection and BloomNode controls;
• $threejs-exposure-color-grading for metering, adaptation, tone mapping, and LUT domains;
• $threejs-dynamic-surface-effects for feature-local screen history;
• $threejs-visual-validation for capture, timing, and lifecycle evidence.
