Ytini is a collaboration between AVL and Jill Naiman of the Harvard-Smithsonian Center for Astrophysics. It is a plugin for Houdini that uses the scientific analysis and visualization tool yt as a data reader.

Ytini uses yt to read volumetric data and convert it into Houdini-readable VDB files. This allows Houdini to read any data format that yt can read, with minimal to no additional effort, not requiring a custom data reader plugin for each now data format, and cutting down weeks of development time per visualization. Support for Adaptive Mesh Refinement (AMR) was added in 2017.

Ytini is an open-source project, with files and tutorials distributed through www.ytini.com.
