[yt-dev] SPH Smoothing Formulation?

Hey everyone, Britton, Devin, and I are writing up the Trident method paper, and we wanted to be explicit about how exactly yt deposits SPH field quantities on to an octree for particle-based fields. Are there any formal equations for this written down anywhere? I realize SPH support was added since the first yt method paper, so it isn't in there, and I cannot seem to find anything in the docs. I wonder if anyone has anything written down for this or if I'm missing it somewhere? Thanks!
