I’ve been pretty happy with the yt streamlines interface and being able to access fields of a dataset on given streamline would be especially useful for a project I’m currently working on. I would be happy to contribute though I’ll admit I do not have any experience working with cython (which I see yt/geometry/selecttion_routines.pyx is written in). </div><div class=""><br class=""></div><div class="">I’d be happy to drop into the slack channel tomorrow to discuss this further. Clicking on the slack link at <a href="http://yt-project.org/community.html" class="">http://yt-project.org/community.html</a>, it looks like I need an invite to join the chat. </div><div class=""><br class=""></div><div class="">Thanks again!</div><div class=""><br class=""></div><div class="">Will</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Aug 2, 2016, at 1:56 PM, Matthew Turk <<a href="mailto:matthewturk@gmail.com" class="">matthewturk@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hi Will,<div class=""><br class=""></div><div class="">Thanks for your email! I just checked, and indeed, that you can't access them. But, I don't think it would be terribly difficult (although likely a bit baroque) to implement the access protocol, and I think it would be a great addition. I think that it would require implementing a streamline data selector in yt/geometry/selection_routines.pyx. The streamline path object itself has a positions attribute, which gives the position at each point in the streamline. This can be accessed in the selection routine in an implementation of select_cell.</div><div class=""><br class=""></div><div class="">I'd be haappy to work through this with you, if you'd like -- you can join our slack channel (it should currently allow guests, or we can invite you) and we can talk through this if you'd like.</div><div class=""><br class=""></div><div class="">-Matt</div></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On Tue, Aug 2, 2016 at 11:40 AM, Will Barnes <span dir="ltr" class=""><<a href="mailto:wtb2@rice.edu" target="_blank" class="">wtb2@rice.edu</a>></span> wrote:<br class=""><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word" class="">Hi all,<div class=""><br class=""></div><div class="">I was wondering if there is currently an effort to implement data access along streamlines in yt 3.x.
