yt 2.4 released!
@ Matthew Turk | Friday, Aug 3, 2012 | 2 minute read | Update at Friday, Aug 3, 2012

We’re proud to announce the release of version 2.4 of the yt Project, http://yt-project.org/ . The new version includes many new features, refinements of existing features and numerous bugfixes. We encourage all users to upgrade to take advantage of the changes.

yt is a community-developed analysis and visualization toolkit, primarily directed at astrophysical hydrodynamics simulations. It provides full support for output from the Enzo, FLASH, Orion, and Nyx codes, with preliminary support for several others. It provides access to simulation data using an intuitive python interface, can perform many common visualization tasks and offers a framework for conducting data reductions and analysis of simulation data.

The most visible changes with the 2.4 release include:

  • A threaded volume renderer, which has been completely rewritten for speed, clarity and extensibility
  • A new plotting mechanism, the “Plot Window,” for easier and more efficient visualization
  • Many improvements to time series analysis, including auto-parallelization
  • A complete rewrite of the Web GUI for yt including a WebGL 3D scene and substantial user interface improvements
  • Integration with the new yt Hub (http://hub.yt-project.org/ ) for sharing of data, scripts and images
  • Extensive additions and improvements to the cookbook

For a complete list of changes in this release, please visit the Changelog ( http://yt-project.org/docs/2.4/changelog.html ). Information about the yt project, including installation instructions, can be found on the homepage: http://yt-project.org/

yt extension modules

yt has many extension packages to help you in your scientific workflow! Check these out, or create your own.

ytini

ytini is set of tools and tutorials for using yt as a tool inside the 3D visual effects software Houdini or a data pre-processor externally to Houdini.

Trident

Trident is a full-featured tool that projects arbitrary sightlines through astrophysical hydrodynamics simulations for generating mock spectral observations of the IGM and CGM.

pyXSIM

pyXSIM is a Python package for simulating X-ray observations from astrophysical sources.

ytree

Analyze merger tree data from multiple sources. It’s yt for merger trees!

yt_idv

yt_idv is a package for interactive volume rendering with yt! It provides interactive visualization using OpenGL for datasets loaded in yt. It is written to provide both scripting and interactive access.

widgyts

widgyts is a jupyter widgets extension for yt, backed by rust/webassembly to allow for browser-based, interactive exploration of data from yt.

yt_astro_analysis

yt_astro_analysis is the yt extension package for astrophysical analysis.

Make your own!!

Finally, check out our development docs on writing your own yt extensions!

We welcome contributions from all members of the yt community. Feel free to reach out if you need any help.

the yt data hub

The yt hub at https://girder.hub.yt/ has a ton of resources to check out, whether you have yt installed or not.

The collections host all sorts of data that can be loaded with yt. Some have been used in publications, and others are used as sample frontend data for yt. Maybe there’s data from your simulation software?

The rafts host the yt quickstart notebooks, where you can interact with yt in the browser, without needing to install it locally. Check out some of the other rafts too, like the widgyts release notebooks – a demo of the widgyts yt extension pacakge; or the notebooks from the CCA workshop – a user’s workshop on using yt.
