Abstracting Rigging Concepts for a Future Proof Framework Design

How to read this

Category

Production talk: a rigging-framework architecture

Contributions

• Presents DNEG's Loom framework, which abstracts rigging concepts into a DCC-agnostic system separating pure rigging logic from implementation details
• Uses operator graphs and procedural rigs to survive the discontinuation of an underlying engine (Fabric Engine)
• Reports better performance than Maya's GPU pipeline via optimized CPU and parallel evaluation

Context

Relates to multithreaded dependency-graph evaluation for character animation (e.g. LibEE: A Multithreaded Dependency Graph for Character Animation), applying graph-based, abstracted evaluation to a future-proof rigging framework.Builds on: LibEE: A Multithreaded Dependency Graph for Character Animation

Correctness

Studio practice, not peer-reviewed; the performance and portability claims are production-validated within DNEG's pipeline, so the comparison against Maya's GPU path reflects their setup rather than a controlled benchmark.

Clarity

Accessible to pipeline and rigging engineers; one read conveys the abstraction strategy and its motivation.

How to read it

Read once for the separation-of-concerns design and the operator-graph approach; revisit only if you are designing a DCC-agnostic rigging framework yourself.
