Natgrid(3NCARG)

💖 Natgrid — the NCAR GRAPHICS era 💖

okay bestie, sit down, hydrate, and let me tell you about Natgrid, a whole package from the NCAR GRAPHICS manual (3NCARG, if we're being precise, and we ARE). it does one thing and it does it gorgeously: gridding 2D randomly-spaced data using a natural neighbor algorithm. ✨

and the way it's built?? single precision AND double precision interfaces exist in BOTH Fortran and C. equal opportunity icon behavior. no cap. 👑

🌸 NAME 🌸

Natgrid is a package for gridding 2D randomly-spaced data using a natural neighbor algorithm. Single precison and double precision interfaces exist in both Fortran and C.

(yes, "precison" — that's exactly how it's spelled in the original and I am NOT touching it, it's part of the lore now 🫶)

🦋 SYNOPSIS 🦋

🌈 FORTRAN single precision

NATGRIDS     -  primary function for gridding.
NNSETI       -  set INTEGER parameter values.
NNGETI       -  retrieve values for INTEGER parameters.
NNSETR       -  set REAL parameter values.
NNGETR       -  retrieve values for REAL parameters.
NNSETC       -  set CHARACTER valued parameters.
NNGETC       -  retrieve values for CHARACTER parameters.
NNGETSLOPES  -  get slope values, if calculated.
NNGETASPECTS -  get aspect values, if calculated.
NNPNTINITS   -  initiate single point mode.
NNPNTS       -  interpolate at a single point.
NNPNTEND     -  terminate single point mode.

🌈 Fortran double precision (not supported on UNICOS)

heads up bestie: double precision Fortran is not supported on UNICOS. if you're on UNICOS, that door is locked, fr fr. 🚫

✨ ACCESS ✨

wanna use the Natgrid entries? then load the NCAR Graphics library ngmath. that's the vibe check, that's the entry fee, that's it. 💅

oh and also?? there's an NCL (NCAR Command Language) interface for Natgrid procedures too. she contains multitudes. 🌸

and that's the whole page, babe. Natgrid, from the UNIX manual, March 1997-1998, NCAR GRAPHICS, Natgrid(3NCARG). she's been iconic since the 90s and she's still serving. go grid some randomly-spaced data, you absolute main character. 💖✨🦋🎀
