Arnold OpenVDB Surface - Arnold for Katana

Volume file formats, such as OpenVDB, will allow storage of much larger datasets while being optimized for random access to volume and level set data, which is more efficient for rendering.

The default implicit plugin is OpenVDB. In addition to the ray extents acceleration, auto bounding box, and auto step size of the new volume API, it brings several production features such as velocity motion blur, scaling of velocity and step_size, and much more.
