ImAnim

ImAnim is a lightweight animation engine that brings modern motion capabilities to applications built with the Dear ImGui immediate-mode GUI framework. It lets developers add rich, smooth animations to user interface elements with minimal boilerplate, matching the responsive nature of ImGui without introducing heavy external dependencies. Support for a wide range of easing functions, tweens, and keyframe clips gives fine-grained control over value transitions like position, scale, opacity, and color. Because it is built to complement ImGui’s design, ImAnim integrates naturally into existing render loops and retains the performance and simplicity that make ImGui popular for tools and development UIs. The project includes examples and demos demonstrating hover effects, timeline control, procedural motion, and complex sequences, making it easier for developers to explore its capabilities. ImAnim targets C++ developers looking to elevate the polish of their graphical interfaces.
