classmethod createChainFromBezierAndUpVectors(numJoints, bezier, upVectors, downAxis=<undefined>, upAxis=<undefined>, opposite=False, resolution=9, parallelTransport=False, parent=None)#

Creates a chain from a guide Bezier curve and matched per-anchor up vectors.

Parameters

  • numJoints (int) – the number of joints to generate

  • bezier (str, BezierCurve, Transform) – the guide bezier curve

  • upVectors (list [list [float] | Vector]) – one up vector per anchor on the Bezier curve

  • downAxis (str) – the ‘bone’ axis; defaults to paya.config.downAxis

  • upAxis (str) – the axis to map to the up vectors; defaults to paya.config.upAxis

  • opposite (bool) – flips the (resolved) down axis; defaults to False

  • parallelTransport – resolve up vector blending using parallel transport; defaults to False

  • resolution/res (int) – the number of parallel-transport solutions to generate along the curve; higher numbers improve accuracy at the expense of performance; defaults to 9

  • interpolation/i: –

    defines how to interpolate values from param: vector pairs:

    • 0 ('None') (you wouldn’t normally want this)

    • 1 ('Linear') (the default)

    • 2 ('Smooth')

    • 3 ('Spline')

  • parent (None, str, Transform) – an optional destination parent for the chain; defaults to None

Returns

The generated chain.
