Title:

    Analytic spherical harmonic gradients for real-time rendering with many polygonal area lights

Presenter(s)/Author(s):



Abstract:


    We develop an analytic formula for spatial gradients of the spherical harmonic coefficients for uniform polygonal area lights, enabling scaling PRT to hundreds of area lights with real-time frame rates.
