nuke.splinewarp.CubicCurve

class nuke.splinewarp.CubicCurve

Bases: object

A baked out curve for a specific frame and view.

Use the getPoint function to get positions along the curve.

Note that some curves, such as the feather curve for a roto shape, are stored as offsets relative to another curve rather than absolute positions.

Methods

param t:: The parameter value to evaluate the curve with. 0.0 is the start of the curve and 1.0 is the end. A value outside this range will throw a ValueError.

getPoint(t) → CVec4

Parameters:: t – The parameter value to evaluate the curve with. 0.0 is the start of the curve and 1.0 is the end. A value outside this range will throw a ValueError.
Returns:: A CVec4 containing the evalution result. If the curve has less than 4 dimension, the extra dimensions will be filled with default values.
