nuke.curvelib.CorrespondencePoints

class nuke.curvelib.CorrespondencePoints

Bases: object

Correspondence points add a relation to the interpolation of two curves. These points are made up of two values; a t-value on the source curve and a corresponding t-value on the destination curve T-values should be in the range [0-1], where 0 is the start of the curve, and 1 is the end of the curve

Methods

addPoint

Adds a correspondence point :param time: Time at which to t_src and t_dest will be set :param t_src: Position on the source curve (where 0=start and 1=end) :param t_dest: Position on the destination curve Note that the correspondence point is not animated.

getAnimCurve

param index

Index to the point to get the associated AnimCurve

getNumPoints

return

Returns the number of correspondence points in the object

getPointValues

param time

Time at which to evaluate point's values

modifyPoint

param time

Time at which to t_in and t_out will be set

removePoint

param index

Index to the point to remove

reset

cps->reset() Resets the correspondence points object to empty
addPoint(time, t_src, t_dest)

Adds a correspondence point :param time: Time at which to t_src and t_dest will be set :param t_src: Position on the source curve (where 0=start and 1=end) :param t_dest: Position on the destination curve Note that the correspondence point is not animated. Animation must be set manually to avoid conflicting with existing points.

getAnimCurve(index, which) → AnimCurve
Parameters

index – Index to the point to get the associated AnimCurve

object for :param which: Whether the source (0) or destination (1) t-value is being modified :return: An AnimCurve object for the timeline of the specified point and src/dest value

getNumPoints()
Returns

Returns the number of correspondence points in the object

getPointValues(time, index)
Parameters

  • time – Time at which to evaluate point’s values

  • index – Index to the point to evaluate

Returns

A tuple containing source and destionation t-values

modifyPoint(time, index, which, t)
Parameters

  • time – Time at which to t_in and t_out will be set

  • index – Index to the point to modify

  • which – Whether the source (0) or destination (1) t-value is

being modified :param t: Position on the curve specified in by ‘which’

removePoint(index)
Parameters

index – Index to the point to remove

reset()

cps->reset() Resets the correspondence points object to empty
