Supplemental Material for Freeform Shadow Boundary Editing

In this document we present additional results for the paper of Mattausch et al. [MIW13]. In particular, we compare silhouette computation methods used as input for the shadow editing algorithm, show some additional editing and animation examples, and show the effect of the ε parameter of the modified shadow volumes which takes a silhouette vertex so to so. 1 Silhouette Computation A comparison of silhouettes of the smooth underlying mesh (computed with the algorithm of Hertzmann et al. [HZ00]) with standard discrete silhouettes and the resulting shadow boundaries are shown in Figure 1.
