VMTKSURFACEARRAYOPERATION(1)

✨ NAME ✨

okay so vmtksurfacearrayoperation — it's a vmtk script, bestie, and its whole name is literally vmtksurfacearrayoperation 💖 that's the manual page we're on, no cap.

🦋 DESCRIPTION 🦋

So here's the tea ☕: vmtksurfacearrayoperation does automatic piping and parsing options — that's the auto-generated blurb it ships with, and yes it says vmtksurfacearrayoperation about itself twice because it's that kind of main character 👑.

What it actually does: it performs an operation between arrays of two surfaces, and then stores the result in the first surface. two surfaces, one array math moment, result goes home with the first one 🏠✨

💅 Input arguments

• -id Id (str,1) — default 0: the script id 🆔
• -handle Self (self,1): handle to self, it's giving self-referential 🫶
• -disabled Disabled (bool,1) — default 0: turn this on and execution and piping get disabled, like a little pause button ⏸️
• -i Surface (vtkPolyData,1): the input surface, your first baddie 🌸
• -ifile SurfaceInputFileName (str,1): filename for the default Surface reader 📂
• -i2 Surface2 (vtkPolyData,1): the second input surface, the duo completes 👯
• -i2file Surface2InputFileName (str,1): filename for the default Surface2 reader 📂
• -operation Operation (str,1) in ['multiplybyc', 'addc', 'add', 'subtract', 'multiply', 'min', 'max'] — default add: the operation to be performed on the array 🧮 and heads up, multiplybyc and addc only require the first input Surface to be specified (the second one can just chill) ✨
• -constant Constant (float,1) — default 0.0: the value of the constant for multiplybyc and addc 🔢
• -iarray InputArrayName (str,1) — default None: the name of the array on the first surface 🏷️
• -i2array Input2ArrayName (str,1) — default None: the name of the array on the second surface; and if you don't specify it, InputArrayName gets used instead, so it's very "same energy" of it 🙈
• -resultarray ResultArrayName (str,1) — default Result: the name of the array where the result of the operation is stored 💾
• -ofile SurfaceOutputFileName (str,1): filename for the default Surface writer ✍️

👑 Output arguments

• -id Id (str,1) — default 0: the script id 🆔 (yes, she's listed again, she contains multitudes)
• -handle Self (self,1): handle to self 🫶 (also back for round two)
• -o Surface (vtkPolyData,1): the output surface — the final look, the glow up, the result of all that array math 💅🔥

lowkey important reminder bestie: multiplybyc and addc are the easy ones — they only need the first input Surface. everything else wants both surfaces present, fr fr 🫡

and that's the whole page, you ate it 🌈💜
