  We present FITE, a First-Implicit-Then-Explicit framework for modeling human
avatars in clothing. Our framework first learns implicit surface templates
representing the coarse clothing topology, and then employs the templates to
guide the generation of point sets which further capture pose-dependent
clothing deformations such as wrinkles. Our pipeline incorporates the merits of
both implicit and explicit representations, namely, the ability to handle
varying topology and the ability to efficiently capture fine details. We also
propose diffused skinning to facilitate template training especially for loose
clothing, and projection-based pose-encoding to extract pose information from
mesh templates without predefined UV map or connectivity. Our code is publicly
available at https://github.com/jsnln/fite.
