Erich Ess on Imaging Vector Fields Using Line Integral Convolution

Mar 1, 2017 · New York, United States of America

We're back in 2017 with Erich Ess, lead engineer on's Core Platform team, presenting on foundational work to visualize fluid motion: Imaging Vector Fields Using Line Integral Convolution by Brian Cabral and Leith Leedom. 


Line Integral Convolution is one of the most intuitive data visualization techniques around.  It's dropping paint in a river to see how the current is flowing:  to visualize a vector field simply take an image and have the vector field smear the colors.  The result is a powerful alternative to using arrows or stream lines.  And while the intuition is very straightforward, the actual mathematics that power the technique are very complex.


Erich Ess (@egerhardess) is a lead engineer on the Core Platform team at His current work focuses on semantics for programmatic represention of distributed processes and advanced monitoring and insight platform for high distributed high volume systems.  Before that he was a CTO in Chicago and an engineer in San Diego.  He studied Computer Science and Pure Mathematics in college and did research in scientific visualization before escaping academia.

Doors open at 7 pm; the presentation will begin at 7:30 pm; and, yes, there will be refreshments of all kinds and pizza.

A little different than previous PWLs, you'll have to check-in with security with your Name/ID. Definitely sign-up if you’re going to attend–unfortunately people whose names aren’t entered into the security system in advance won’t be allowed in. 

After Erich presents the paper, we will open up the floor to discussion and questions.  

We hope that you'll read the paper before the meetup, but don't stress if you can't. If you have any questions, thoughts, or related information, please visit #pwlnyc on slack, our GitHub repository, where you can also find the paper, or add to the discussion on this event's thread.

Additionally, if you have any papers you want to add to the repository above (papers that you love!), please send us a pull request. Also, if you have any ideas/questions about this meetup or the Papers-We-Love org, just open up an issue.

  • Papers We Love

    What was the last paper within the realm of computing you read and loved? What did it inspire you to build or tinker with? Come share the ideas in an awesome academic/research paper with fellow engineers, programmers, and paper-readers. Lead a session and show off code that you wrote that implements these ideas or just give us the lowdown about the paper (because of HARD MATH!). Otherwise, jus...
