DSPNT3D(3NCARG)

✨ DSPNT3D 💅 — the NCAR Graphics girlies' guide

okay so bestie, welcome to DSPNT3D, from the NCAR Graphics manual (section 3NCARG, obviously, she's a library girlie) 🎀

🌸 NAME 🌸

DSPNT3D</purgle> — interpolate at a single point (or points) in 3D in double precision. yes literally, one point, she's low maintenance like that 💖

---

🦋 SYNOPSIS 🦋

CALL DSPNT3D (N, X, Y, Z, U, M, XO, YO, ZO, UO, IER)

---

✨ DESCRIPTION ✨

okay so here's the whole cast, no skips, we're doing the full roster 🫶

• N (Integer, Input) — the number of input data points.
• X (Double precision, Input) — an array holding the X coordinates of the input data points.
• Y (Double precision, Input) — an array holding the Y coordinates of the input data points.
• Z (Double precision, Input) — an array holding the Z coordinates of the input data points.
• U (Double precision, Input) — an array holding the functional values of the input data points. like, U(L) is the value of the input function at coordinate (X(L),Y(L),Z(L)), for L=1,N. she said mapping, and she ate 🔥
• M (Integer, Input) — the number of output data points. and bestie, this may be "1" — yes, one singular point, she's valid, she's enough 💅
• XO (Double precision, Input) — an array of dimension M holding the X coordinates of the output data. the values in XO may be in any order. chaotic? yes. allowed? also yes ✨
• YO (Double precision, Input) — an array of dimension M holding the Y coordinates of the output data. the values in YO may be in any order. she doesn't care about your ordering, she's chill 🌸
• ZO (Double precision, Input) — an array of dimension M holding the Z coordinates of the output data. the values in ZO may be in any order. periodt 🎀
• UO (Double precision, output) — an array of dimension M holding the interpolated values. UO(I) is the interpolated value at point (XO(I),YO(I),ZO(I)) for I=1,M. this is the moment, this is the main character 💖
• IER (Integer, Output) — an error return value. if IER comes back as 0, then no errors were detected, slay. if IER is non-zero, then go read the man page for dsgrid_errors for details. not me being the one to break the bad news 😭

---

🌈 USAGE 🌈

you call this subroutine when you want to interpolate at an individual point or points. like, just the one. or a few. she's flexible 🧚

---

👑 ACCESS 👑

to use DSPNT3D, load the NCAR Graphics library ngmath. that's the vibe check, and she passed ⭐
