Explore the intricacies of lerp smoothing in this comprehensive 57-minute conference talk recorded at Guadalindie 2024. Delve into the challenges of framerate dependence, linear motion, and the non-linear behavior of lerp smoothing. Discover techniques for achieving continuity, unraveling recursion, and implementing framerate-independent solutions. Learn about half-life concepts and gain practical insights summarized in a convenient "tldr" section. The talk concludes with a Q&A on the importance of mathematical experimentation and bonus slides covering differential calculus and spring physics, providing a thorough understanding of this complex topic in game development and animation.
