Differentiable Time-Gated Rendering
In this paper, we develop a novel analytic formula for the spatial gradients of the spherical harmonic coefficients for uniform polygonal area lights.
Analytic Spherical Harmonic Gradients for Real-Time Rendering with Many Polygonal Area Lights
In this paper, we develop a novel analytic formula for the spatial gradients of the spherical harmonic coefficients for uniform polygonal area lights.
