code for SIGGRAPH ASIA 2025 paper "Gaussian Integral Linear Operators for Precomputed Graphics".

project page: https://suikasibyl.github.io/gilo/

This work provides a general framework for representing integral linear operators, and we provides 3 prototype applications:

• pde: linear PDE with GILO as precomputed Poisson kernel;
• prt: precomputed radiance transfer using GILO as transfer kernel;
• fluorescent: fluorescent rendering with GILO as re-radiation matrix;
