Title:
- Distributing Liquids using OpenVDB
Presenter(s)/Author(s):
Abstract:
From large, stormy oceans to cities being obliterated by tsunamis, demands on liquid simulations in Visual Effects are ever-growing in terms of complexity and scale. Improved performance through multi-threading alone is no longer proving sufficient. We present a light framework built on OpenVDB and OpenMPI that efficiently distributes sparse volumetric and spatially-organised point data. This greatly improves performance and increases our data sizes in production.
