yt development - HEALpix and Contour Tree

yt development - HEALpix and Contour Tree

Monday, Feb 21, 2011

@ Matthew Turk

This week there was not very much yt development. However, a few notes may be of interest. SamS has updated the HEALPix camera to support ordered projections; what this means is that you can now make volume renderings using a standard color transfer function, or even the Planck transfer function, that cover 4pi of the sky. I am still working on integrating a method for creating images easily, but for now the scripts from last week should work.
yt development - All-sky column density calculation

yt development - All-sky column density calculation

Monday, Feb 14, 2011

@ Matthew Turk

This week I added the ability to calculate all-sky column densities. This functionality uses HEALpix to calculate equally-area regions on the sky and then shoots out rays from a central source to some fixed radius, accumulating values of a field along the way. Although so far I’ve only used it to calculate column densities of “Density” it could be used for other values as well, including all- sky weighted averages of quantities.

yt development - Documentation

@ Matthew Turk

As a result of progress in my scientific goals, and the application of recent yt developments to them, I did not make many changes or developments in yt this week. When I did work on yt, I primarily spent time re-organizing the documentation and fixing several errors. I have added an “installation” section, consolidated a few sections, and wrote two new sections on how to make plots and on how to generate derived data products.
yt development - Time series, and more

yt development - Time series, and more

Monday, Jan 31, 2011

@ Matthew Turk

Not much yt development went on in the last week; I spent some time working with Enzo and driving forward simulation goals, which resulted in some development that directly benefited those simulation goals. However, this fortuitously coincided with work I have been eager to return to for quite some time: namely, time series analysis! Time Series Analysis The problem with time series analysis in yt has, to this point, been an issue of verbosity and clunkiness.
yt development - 2.0, Cython, and physics module wrapping

yt development - 2.0, Cython, and physics module wrapping

Monday, Jan 24, 2011

@ Matthew Turk

This is the second blog entry in the weekly series, with some updates on what took place last week with respect to yt development. One of the more exciting things is the final one, which is the start of what I want to focus on for the next couple months or years: integration of physics modules with analysis code, and then the ultimate inversion of that relationship. yt-2.0 This week saw the release of yt 2.
yt development - star particle rendering, simple merger trees and documentation

yt development - star particle rendering, simple merger trees and documentation

Monday, Jan 17, 2011

@ Matthew Turk

This is the first of a new series of “what’s up with yt” blog posts I’m going to be writing. By keeping this log, I hope that maybe some things that would otherwise get lost in the version control changesets will get brought to greater light. This covers the time period of the first couple weeks in January. Star Particle Rendering On the mailing list, the question of adding star particles to a volume rendering was raised.

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.
