💅 SHOWMATS 💅

okay so real talk, bestie — this is a BRL-CAD User Commands page, and the command we're stanning today is showmats from the nged girlies. it's not complicated, it's just precise, and precision is literally the vibe.

✨ NAME ✨

showmats — lists the transformation matrices encountered along the specified path, and also lists the accumulated matrix at the end of that path. that's it, that's the whole job, and she does it flawlessly. 🎀

🌸 SYNOPSIS 🌸

showmats [-a] {path}
one command, one optional flag, one path. short and iconic. periodt. 💅

🦋 DESCRIPTION 🦋

so showmats walks along the path you give it and lists every transformation matrix it bumps into along the way, then at the very end of the path it hits you with the accumulated matrix — the sum-of-everything final answer. it's giving "receipts, then the grand total." 🧾✨

now here's the little plot twist you need to know about: if any member shows up more than once in a combination along the path, then a matrix gets listed for each occurrence of that member — yes, every single one, she's thorough — and the accumulated matrix will only use the first occurrence. so like… she notes the duplicates for you, but she doesn't double-count them at the end. fair and balanced. 🙈

and if you're the kind of girl who needs more digits in her life, the -a option is right there: it returns the accumulated matrix as a space delineated list with 6 significant digits — as opposed to the default 3. more numbers, more accuracy, no cap. 🔥

related commands, if you want to keep the party going: putmat, copymat, and listeval. go be great. 🫶

💜 EXAMPLES 💜

the example shows showmats being used to list the transformation matrices along the specified path plus the accumulated matrix for the entire path. a little demonstration, as a treat.

Example 1. List the transformation matrices along a path and the accumulated matrix for the path. ⭐

mged>showmats head/skull/jaw

Lists the transformation matrices along the path head/skull/jaw and the accumulated matrix for the entire path. literally that simple, and honestly? obsessed. 🍓
