Hi is always me :)
regard my MRampAttribute
I would use this class just for find the inbetween value of some keys!
but I don't wanna create any ramp attribute on the node, cause I'm not
interested on give to the user the
oppurtunity of edit this key from maya, but only by my own interface!
for that I want to know if is there a way for use this class in the
node, just for calculating and get the value,
without create the node, like this I can avoid the error that I got
everytime I open the attribute editor!
my idea is to call this class also in my interface for edit the keys!
otherwise if you know a function for get the inbetween value, between
each keys in the list,
should be the same!
a small example of what I need :
if I have a list of keys like this
[{pos: 0.0, value: [-9.0, 4.0, 6.0]},
{pos: 0.5, value: [9.0, 40.0, -16.0]},
{pos: 1.0, value: [9.50, -14.0, 60.0]}...and so on]
the function should do something like GetColorAtPosition of the
MRampAttribute,
means that at a specific Position (es. 0.75) the function must return
the value, maybe with linear interpolation, for keep simple!
for still using the MRampAttribute, or a custom function is the same!
any idea?
