representation is compliant to topology changes during gra-
dient updates (see Fig. 5), and is therefore able to recover
from bad local optima. In contrast, sub-optimal topology
that happens during optimization, such as inverted faces,
prevents ViSER to improve given more iterations. Com-
pared to meshes with finite number of vertices, implicit
shape representation maintains a continuous geometry, en-
abling us to recover detailed shape without additional cost
in rendering high-res meshes.
