# Importance Resampling for BSSRDF

## One-sentence takeaway

Pixar BSSRDF resampling; production sampling.

## Problem

Predecessor chain King13 → Pixar resampling. This paper's job: Pixar BSSRDF resampling; production sampling.

## Design

Pixar BSSRDF resampling; production sampling. Lineage: King13 → Pixar resampling.

## Evidence

SIGGRAPH Talks / Pixar TM 2016. no DOI — use the source URL. Pixar BSSRDF resampling; production sampling.

## Limitations

Talk or course notes, not a full TOG derivation. Use the PDF/DOI in Links; do not invent a journal version.

## Implications for Broadside

Anoptic has a forward+ mesh renderer and is betting on FMM+RC 3D GI. Translucent materials / SSS is the missing appearance model for skin, marble, wax, leaves, and interiors. Do not claim they already have SSS.

## Bottom line

Mint this 2016 SIGGRAPH Talks / Pixar TM paper. Pixar BSSRDF resampling; production sampling.
