I'm just introducing myself as one of the successful Google Summer of Code students that will be working with yt this summer.
I will be working with Nathan and Matt on aspects of the demeshening project. This will have a particular focus on developing an interface to calculate the value of an interpolated particle field at an arbitrary location using a couple of approaches.
You can learn more about my project and follow my progress here. https://ashkelly.github.io/gsoc-blog/
I will attempt to update the blog at least every couple of weeks.
Feel free to ask any questions!
