LerpAaa

LerpAaa is a minimalist, open-source web application designed for creating and sharing animated linear interpolations (lerps) between two or more data points. The tool is particularly useful for visualizing smooth transitions, such as those in graphics programming, game development, or data-driven animations. LerpAaa operates entirely in the browser, requiring no installation or backend infrastructure, making it accessible to anyone with a web browser.

The application allows users to input keyframes—sets of values at specific times—such as coordinates, colors, or numerical parameters. LerpAaa then generates an interpolation curve between these points, which can be previewed in real-time. Users can adjust the interpolation method (e.g., linear, quadratic, or cubic) and tweak easing functions to control the pacing of the animation. The results can be exported as JSON or embedded in web projects via a simple iframe or JavaScript API.

LerpAaa was created to simplify the process of experimenting with lerps, which are fundamental in computer graphics for creating fluid motion. It is particularly popular among developers, artists, and educators who need a quick way to prototype animations without dealing with complex code. The project is hosted on GitHub under an open-source license, encouraging contributions and modifications.

While LerpAaa is not a full-fledged animation tool like Adobe After Effects or Blender, its simplicity and focus on lerps make it a valuable resource for specific use cases. The tool’s design emphasizes clarity and efficiency, ensuring that users can iterate on their animations quickly. It is frequently used in tutorials for teaching interpolation concepts and as a reference for implementing lerps in custom applications.
