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
