OpenVDB 11.0 Updates

Last modified: 17 December 2024

Updated from Version 7.0 to Version 11.0

OpenVDB is a library comprising a compact hierarchical data structure and a suite of tools for the efficient manipulation of sparse, possibly time-varying, volumetric data discretized on a three-dimensional grid. It is based on VDB, which was developed by Ken Museth at DreamWorks Animation, and it offers an effectively infinite 3D index space, compact storage (both in memory and on disk), fast data access (both random and sequential), and a collection of algorithms specifically optimized for the data structure for common tasks such as filtering, constructive solid geometry (CSG), discretization of partial differential equations, voxelization of polygons, skinning of particles, volumetric compositing and sampling.

Enhanced Performance:

The transition to Open VDB 11 provides significant performance boosts, enabling faster computations and more efficient memory usage across all volumetric operations.

Flame, Smoke and Water (Turbulence and LW Flow):

With the new Open VDB 11, the flame tool now supports more intricate and detailed simulations, resulting in more realistic fire and smoke effects. Flow benefits from the upgraded Open VDB library with enhanced accuracy and stability in fluid simulations, producing more lifelike water behaviours.

Optimized Simulations:

Enjoy smoother and faster rendering of complex flame dynamics, allowing for higher fidelity in visual effects production.
