IDPLTR(3NCARG)

💖 IDPLTR — the NCAR Graphics glow-up 💖

okay bestie, so this is a page from the NCAR GRAPHICS manual (the 3NCARG section, if you're keeping track 🎀), and today's main character is IDPLTR. Buckle up.

✨ NAME ✨

IDLPTR — literally plots the triangulation that a prior call to either IDBVIP or IDSFFT already cooked up. no cap, that's the whole job. 🦋

✨ SYNOPSIS ✨

CALL IDPLTR (NDAT,XDAT,YDAT,IWRK)

✨ C-BINDING SYNOPSIS ✨

#include <ncarg/ncargC.h>

void c_idbvip (int ndat, float *xdat, float *ydat, float *iwrk)

✨ DESCRIPTION ✨

okay so here's the tea on every single argument, and yes we're going through all of them 💅

• NDAT — the number of data points. this is the argument NDP from that prior call to IDBVIP or IDSFFT you did earlier. it's giving "you already know her". 👑
• XD — an array of dimension NDP holding the X coordinates of the data points (again, straight from your prior call to IDBVIP or IDSFFT). 📍
• YD — an array of dimension NDP holding the Y coordinates of the data points (from prior call to IDBVIP or IDSFFT, iykyk). 📍
• ZD — an array of dimension NDP holding the Z coordinates of the data points (from prior call to IDBVIP or IDSFFT). 📍
• IWRK — an integer work array of dimension at least 31*NDP + NIP (this is the argument IWK from your prior call to IDBVIP or IDSFFT). 🧺

🌸 heads up bestie: you, the caller, are the one responsible for doing the SET call that maps the triangles to the correct position on the plotter frame. the routine is NOT doing it for you. no free rides. 💀

🙈 also, real talk: some triangle edges get drawn twice. and no attempt is made to prevent that. it just is what it is. iconic behaviour honestly.

✨ C-BINDING DESCRIPTION ✨

the C-binding argument descriptions are the same as the FORTRAN argument descriptions. same vibes, different font. 🫶

✨ ACCESS ✨

to use IDPLTR or c_idpltr, you load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — and preferably in that exact order, okay? order matters, bestie. don't be chaotic. 🌈

and that's the whole page, bestie!! this lil beauty comes to you from the UNIX manual, November 1995 vintage, filed under IDPLTR(3NCARG) — yeah she's an older queen but she still slays 💅✨ mwah, go plot something gorgeous 🎀🦋
