Clothing virtual characters is a time-consuming and often manual process.
Outfits can be composed of multiple garments, and each garment must be fitted
to the unique shape of a character. Since characters can vary widely in size
and shape, fitting outfits to many characters is a combinatorially large
problem. We present Bolt, a system designed to take outfits originally authored
on a source body and fit them to new body shapes via a three stage transfer,
drape, and rig process. First, our new garment transfer method transforms each
garment’s 3D mesh positions to the new character, then optimizes the garment’s
2D sewing pattern while maintaining key features of the original seams and
boundaries. Second, our system simulates the transferred garments to
progressively drape and untangle each garment in the outfit. Finally, the
garments are rigged to the new character. This entire process is automatic,
making it feasible to clothe characters at scale with no human intervention.
Clothed characters are then ready for immediate use in applications such as
gaming, animation, synthetic generation, and more.
