Title:
- Bond: USD-Integrated Hybrid CPU, GPU Deformation System
Presenter(s)/Author(s):
Abstract:
We introduce Bond, a proprietary deformation system able to load geometry data directly from PixarTM Universal Scene Description (USD) and to compute complex deformation chains on the GPU us- ing NVIDIA® CUDA®. Bond also integrates tightly with Autodesk Maya®. This system follows on from our work to integrate USD into our animation pipeline [Baillet et al. 2018].
Bond has been used to deform all characters and props on the Peter Rabbit 2 movie’s 1300 shots to achieve high frame rate during playback and rig interaction.
