Hi All,
I have searched for this info, but as yet no luck. hopefully some knowledgeable
Nuker can help...
Bezier node:
------------------------------------------------------------
I can't seem to find what the different curve interpolation types refer to
exactly in the Bezier node curve shape field.
As in:
shape {{curve [Z] x1 0 [s0] ...}}
where 'Z' is zero or more of the following:
['i', 'k', 'l', 'C', 'L', 'R', 'K']
I have got as far as:
C = Cubic
L = Linear (or Horizontal if the keyframe pairs are followed by 's0')
R = Catmull-Rom
K = Constant
Smooth interpolation leaves the field blank
but what do the 'i', 'l', 'k' refer to?
Also, what exactly does the 's0' in a curve with Horizontal interpolation refer
to?
Roto node:
------------------------------------
I have found that the curve interpolation types are controlled by an integer
which relates more or less to the Bezier curve interpolation flags above.
Specifically:
516 = Cubic
258 = Linear
515 = Catmull-Rom
275 = Horizontal
256 = Smooth
Does anyone have access to a full description of all the parameters and
permutations for curve interpolation type for Bezier and Roto nodes?
Thanks in advance.
