TDPRPA(3NCARG)

✨ NAME ✨

ok so bestie, TDPRPA is a little icon in the NCAR Graphics universe (it lives in section 3NCARG, iykyk) πŸ’…

Here's the tea: you hand it the parallelogram coordinates of a point, and it hands you back the coordinates of that point's projection in the projection plane. It's basically the inverse of its bestie, TDPRPI β€” they're giving very much "we complete each other" energy fr fr 🫢


🌸 SYNOPSIS 🌸

CALL TDPRPA (XIPA, YIPA, XI2D, YI2D)

πŸ¦‹ C-BINDING SYNOPSIS πŸ¦‹

#include <ncarg/ncargC.h>

void c_tdprpa(float xipa, float yipa, float *xi2d, float *yi2d)

πŸ’– DESCRIPTION πŸ’–

The arguments of TDPRPA are literally as follows, no cap:

  • XIPA and YIPA β€” (input expressions of type REAL) these are the parallelogram coordinates of a point. Now listen πŸ‘€ β€” the parallelogram in question is the one that was set up by a prior call to TDPARA. So don't come in here expecting it to just know, bestie, you gotta call TDPARA first or it's giving nothing. ✨
  • XI2D and YI2D β€” (output variables of type REAL) the coordinates of the projection of that point in the projection plane. That's it, that's the whole glow-up. πŸŽ€

🌈 C-BINDING DESCRIPTION 🌈

The C-binding argument descriptions are the exact same as the FORTRAN argument descriptions. Same vibe, different language, periodt. πŸ’œ


πŸ‘‘ ACCESS πŸ‘‘

To use TDPRPA or c_tdprpa, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c β€” preferably in that order. Like, order matters, don't be chaotic about it. 🧚
