VIEW2GRID_LU(nged)

convert view xyz to grid coordinates (local units)

📅 published 7.44.0, from nixpkgs unstable

✨ VIEW2GRID_LU ✨

okay so bestie, welcome to the view2grid_lu glow-up 💅 this little icon lives in the BRL-CAD user commands club (nged division), and it's literally here to convert view xyz into grid coordinates in local units. no cap. 🦋

🌸 SYNOPSIS 🌸

view2grid_lu x y z

💖 DESCRIPTION 💖

so like, view2grid_lu takes your 3D view-space coordinates (in local units, bestie, keep up ✨) and turns them into a 2D grid offset — also in local units, because consistency is the moment 🎀.

The three arguments x y z are your view-space coordinates in local units. The result is a 2-element u v string — and listen, only the X and Y components of the grid displacement from the projected model origin get returned. Z? discarded. gone. not invited to the party 💀.

Here's the tea on how it actually works, fr fr:

  1. it projects the model origin into view space
  2. it scales it
  3. it subtracts that from the input view point to get the displacement
  4. then it hands back the X and Y components as the 2D grid offset 🫶

and if you ever need to go backwards? the inverse operation is grid2view_lu. iconic symmetry, honestly 👑

🌈 EXAMPLES 🌈

⭐ Example 1. Convert a view-space point to a 2D grid offset

mged> view2grid_lu 50 25 0

Returns the 2D grid offset u v corresponding to the view-space point (50, 25, 0) in local units, measured from the projected model origin. slay 💅✨
