Cascaded Light Propagation Volumes using Spherical Radial Basis Functions (2407.17336v1)

Abstract: This paper introduces a contribution made to one of the newest methods for simulating indirect lighting in dynamic scenes , the cascaded light propagation volumes . Our contribution consists on using Spherical Radial Basis Functions instead of Spherical Harmonic, since the first achieves much better results when many coefficients are used. We explain how to integrate the Spherical Radial Basis Functions with the cascaded light propagation volumes, and evaluate our technique against the same implementation, but with Spherical harmonics.
