hou.spline function

This animation function for an animated parameter fits a spline through consecutive keyframe values that also use the hou.spline() function. The resulting spline interpolates the channel values at the keyframes, and slope values are not used.

spline() → float

This function is one of the special animation functions that use the current playbar time and information in the parameter’s keyframes, such as in and out values, tangents, acceleration, etc., to evaluate themselves. Because the information needed to evaluate these functions comes from the keyframes, these functions take few or no parameters.

Calling this function from outside a parameter’s expression will raise a hou.NotAvailable exception.
