[cc'ing directly Nathan in case the mail gets stuck in Mailman]
I started working on the proposal for the project idea *Interpolating particle data onto grids*. After, familiarizing myself with the background information that you pointed to, I have few doubts which are as follows:
1. The YTEP-32 and paper by Dan Price mention "scatter" approach for interpolation. I could not find any material on "gather" approach. Do you have anything handy in this regard? Or should I take the path of scatter approach and proceed further?
2. The project idea lists one of the deliverables as the ability to interpolate data onto a uniform resolution mesh. In YTEP-32 you have plotted slice and projection plots using octree and directly using particle data. Is my understanding correct? If we are able to plot the sph data with this particle-centric approach, then what is expected to be delivered with respect to this project idea.
3. The optional deliverables list the ability to interpolate particle data onto an octree mesh. Is this not the current approach (yt version 3.*)?
If most of my understanding is not correct, I would love to clarify all these doubts as soon as possible, so that I work on the proposal. Thank you for your time!
