✨ TRACK(nged) — the track command, explained by your fave Unix bestie 💅

okay so real talk, this is the nged manual page for track, and it's lowkey one of the cutest little builders in BRL-CAD. 🎀 Let's get into it.

🌸 NAME 🌸

track — builds a simple representation of the linked track of a vehicle such as a tank. yes, an actual tank. main character energy fr fr 🔥

✨ SYNOPSIS ✨

track [parameters>]

💖 DESCRIPTION 💖

okay so track builds a simple representation of the linked track of a vehicle such as a tank. iconic behaviour honestly. 🫶

if you run it with no command line arguments, the track command will prompt you for all the required input. it's giving helpful. like it literally asks you what it needs, no cap.

the vehicle is assumed to be axis-aligned with the front in the +x direction. note that down bestie, it matters. 📝

a combination name for the track is built by appending a unique number to the string track. cute little auto-naming moment. ✨

the information about the track may be included on the command line, and — this is the important bit — it is order-dependent. so do not be out here shuffling your numbers around like a playlist, the order is the order. 🙈

the parameters are, in order:

  • x coordinate of center of frontmost roadwheel.
  • x coordinate of center of rearmost roadwheel.
  • z coordinate of center of all roadwheels.
  • radius of all roadwheels.
  • x coordinate of center of drive wheel (rear).
  • z coordinate of center of drive wheel (rear).
  • radius of drive wheel.
  • x coordinate of center of idler wheel (front).
  • z coordinate of center of idler wheel (front).
  • radius of idler wheel.
  • y coordinate of right side of track.
  • y coordinate of left side of track.
  • track thickness.

thirteen whole values. count them. the order is doing so much work here. 💀

🔥 EXAMPLES 🔥

this example shows the use of the track command with arguments to build a simple track. we love a demo. 👑

🦋 Example 1. Build a simple track.

mged>track 500 0 10 10 -50 50 10 550 50 10 -50 -20 2

builds a simple track using the provided arguments. that's it, that's the whole vibe. slay. 🌈

reminder: the command line arguments are order-dependent, so if your track comes out cursed, check that you didn't shuffle the numbers before you blame the software. 😭

and that's the page! 🎀 this one's from the BRL-CAD manpage set, TRACK(nged) — go build a tank track, you absolute icon. ⭐💅
