Math In Game Development Summit: Getting There in Style: Intro to Interpolation and Control Systems


Procedurally animating an object towards a desired position is ubiquitous in game development. Most developers know lerp, but struggle if lerp doesn't "feel right". When the target point is moving, or when the situation is continuous, instead of transition over a fixed duration, often additional layers of lerp, or other ad-hoc solutions are created. This is unfortunate, because there are many well-studied solutions. This beginner-to-intermediate talk will survey the most important techniques every programmer should have in their toolbox, and give you a framework for thinking about different cases and selecting the best tool for the job.
