Object Hierarchy | Related C++ Class: FCurveKey
FCurveKey
v1.0
The FCurveKey represents a key on an FCurve and is used to access and modify
information about that key.
Note: For more information about interpolation and extrapolation
for fcurves. For more information, see "FCurve Interpolation and
Extrapolation" in the Softimage user guide.
