DSPNT3S(3NCARG)

💖 DSPNT3S 💖

okay bestie, so this is a page from the NCAR GRAPHICS manual (that's the manual name, we're folding it in up top, you're welcome) and it's literally all about interpolating at a single point (or, like, points) in 3D, in single precision. it's giving "math but make it sparkly." ✨

✨ NAME ✨

DSPNT3S — interpolate at a single point (or points) in 3D in single precision 🎀

🌸 SYNOPSIS 🌸

CALL DSPNT3S (N, X, Y, Z, U, M, XO, YO, ZO, UO, IER)

💅 DESCRIPTION 💅

okay so here's the whole cast of characters, no cap, every single one matters:

• N (Integer, Input) — the number of input data points. that's it, that's the count 💜
• X (Real, Input) — an array holding the X coordinates of the input data points.
• Y (Real, Input) — an array holding the Y coordinates of the input data points.
• Z (Real, Input) — an array holding the Z coordinates of the input data points.
• U (Real, Input) — an array holding the functional values of the input data points. so, like, U(L) is the value of the input function at coordinate (X(L),Y(L),Z(L)), for L=1,N. iykyk 🦋
• M (Integer, Input) — the number of output data points. and yes bestie, this may be "1" — one singular point is a totally valid vibe 👑
• XO (Real, Input) — an array of dimension M containing the X coordinates of the output data. the values in XO may be in any order. any order!! chaos is allowed 💀
• YO (Real, Input) — an array of dimension M containing the Y coordinates of the output data. the values in YO may be in any order.
• ZO (Real, Input) — an array of dimension M containing the Z coordinates of the output data. the values in ZO may be in any order.
• UO (Real, output) — an array of dimension M containing 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. 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 refer to the man page for dsgrid_errors for the details, because that's where the tea is ☕

🌈 USAGE 🌈

this subroutine is what you call when you want to interpolate at an individual point, or points. like, specifically. one at a time energy. 🎀

🧚 ACCESS 🧚

to use DSPNT3S, load the NCAR Graphics library ngmath. that's the whole move. 💖

and that's the whole page, bestie!! this one lived in the UNIX manual, dated September 1997-1998, and honestly? iconic for its time. interpolate responsibly. mwah 🍓💜✨
