Psyop releases Open Sourced Shader “JF Nested Dielectric”

Psyop and Psyop’s Head of Lighting (NY) Jonah Friedman proudly present JF Nested Dielectric, an open sourced nested dielectric shader for Solid Angle’s Arnold Renderer.

In large part, this initiative is an implementation of the 2002 paper “Simple Nested Dielectrics in Ray-traced Images by Charles M. Schmidt and Brian Budge” and is meant to solve one problem: efficient, physically-plausible rendering of nested dielectric surfaces in production.

It’s also capable of spectral dispersion, direct refraction of light sources, production-feasible ray traced blurry caustics. It has a few different optimization techniques built in to improve render times, including Russian Roulette and energy tracking and clamping throughout the ray tree.

Since it’s release into the Arnold community yesterday morning, Jonah has already received feedback from users who have modified his code — JF Nested Dielectric now works in Linux, too.

Enjoy it!
