Custom F-Curves in Houdini

One seemingly hidden feature in Houdini is the power to attach expressions to time segments between keyframes. In this tutorial, Adam will show you how to harness this feature to create your own custom interpolation model. We are going to make our own full-featured overshoot f-curve, which will read the incoming channel velocity and create an oscillating motion that exponentially decreases until it arrives at the exiting keyframe value.

This tutorial is intermediate to advanced level, with most of it being done in python. Later, Adam shows how convert the code to HScript.
