# Efficient Rendering of Human Skin

## One-sentence takeaway

d'Eon–Luebke–Enderton 2007: sum-of-Gaussians skin — the real-time / GPU skin that Jimenez and GPU Gems 3 shipped.

## Problem

Donner–Jensen 2005 layers plus Borshukov / Green convolutions: accurate enough, not GPU-separable. Need a texture-space SoG that matches layered diffusion.

## Design

Fit the multi-layer diffusion profile to a sum of Gaussians; convolve irradiance maps. Lineage: DJ05 + Borshukov/Green → d'Eon07 → Jimenez / QD SoG.

## Evidence

EGSR 2007, DOI 10.2312/egwr/egsr07/147-157. NVIDIA PDF: https://www.nvidia.com/docs/IO/40506/Eugene_dEon_Efficient_Skin.pdf.

## Limitations

Texture-space, not screen-space (Jimenez). Homogeneous-per-texel. Separable SSS is the later cheap version.

## 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 d'Eon 2007 skin. Cite Donner 2005 and Borshukov 2003.
