💅 ISIZE (nged) 💅

okay bestie, welcome to the <pink>nged</pink> corner of the BRL-CAD user commands manual. this one's short, sweet, and does exactly one (1) thing. let's get into it 🎀

✨ NAME ✨

isize — returns the inverse of the current view size, that's it, that's the whole gig 🫶

🌸 SYNOPSIS 🌸

isize

🦋 DESCRIPTION 🦋

so the isize command returns the reciprocal of the current view size, in your current working units. it's a read-only getter, meaning it just hands you a number and vibes — no arguments are accepted, so don't even try it 🙈

the inverse view size is related to your current zoom level, lowkey math-coded. it equals 1 / view_size, where view_size is whatever the size command gave you. so:

  • a larger isize value = a more zoomed-in view (smaller view size)
  • a smaller isize value = a more zoomed-out view

this value is primarily useful in scripts that compute view-space to model-space scaling factors. so if you're out here scripting, this is your girl 💅

🔥 EXAMPLES 🔥

Example 1. Get the inverse view size

mged> isize

returns the reciprocal of the current view size in working units — for example: 0.001 when the view size is 1000 mm. slay ✨

Example 2. Use isize in a calculation

mged> set inv [isize]
mged> set sz [size]
mged> expr {$inv * $sz}

this retrieves both isize and size and verifies their product equals 1.0. math checks out, periodt 👑
