Gaussian Shadow Casting for Neural Characters

Figure 1 . Gaussian Shadow Casting (GSC): Our method is able to reconstruct 3D neural characters from a sparse set of videos in settings with strong directional illumination. GSC uses a sum of Gaussians density model to cast secondary shadow rays efficiently with an analytic formula. Our method learns to remove shadows from the neural color field, allowing us to relight in novel illuminations. All faces are blurred for anonymity.
