Abstracting rigging concepts for a future proof framework design

[Digipro’18 preprintSeveral years ago DNEG set out to build Loom, a new rigging framework in a bid to improve the performance of our Maya animation rigs. This talk is an update on its development in the light of the discontinuation of its original evaluation back-end, Fabric Engine. In particular, we describe the design choices which enabled us to achieve a DCC agnostic rigging framework, allowing us to focus on development of pure rigging concepts. Also how this setback prompted us to extend the framework to properly deal with the deformation side of rigs, targeting memory efficiency, GPU/CPU memory interaction and high-end performance optimizations.
