Musical String Vibration
A tube mesh follows a Catmull-Rom curve resampled every frame from the closed-form standing-wave equation
y = A·sin(nπx)·cos(ωt), cycling through harmonics n=1-5 with a quick "pluck" fade-in on
each switch. Thin envelope lines trace the vibration's outer amplitude bounds. Drag to orbit.
String length: 8 units
