hou.linear function

This animation function for an animated parameter linearly interpolates between the left keyframe’s outgoing value and the right keyframe’s incoming value.

linear() → 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.
