# Subdivision Next-Event Estimation for Path-Traced Subsurface Scattering

## One-sentence takeaway

Unbiased NEE through refractive SSS interfaces.

## Problem

Predecessor chain Path-traced SSS noise → SNEE. This paper's job: Unbiased NEE through refractive SSS interfaces.

## Design

Unbiased NEE through refractive SSS interfaces. Lineage: Path-traced SSS noise → SNEE.

## Evidence

EGSR (Experimental Ideas) 2016. no DOI — use the source URL. Unbiased NEE through refractive SSS interfaces.

## Limitations

Read the cited predecessors before treating this as a drop-in Anoptic shader. Do not claim the library already implements it.

## Implications for Broadside

Anoptic has a forward+ mesh renderer and is betting on FMM+RC 3D GI. Skin is the first character-appearance hole: translucent dermis, not another BRDF lobe. Do not claim Anoptic already has SSS.

## Bottom line

Mint this 2016 EGSR (Experimental Ideas) paper. Unbiased NEE through refractive SSS interfaces.
