A collection of visual effect widgets for Dear ImGui.

This repository contains two independent ImGui libraries, each in its own sub-repository:

you can test is with this Emscripten demo

macOS-style Genie effect and Linux/Gnome-style Wobbly windows.

• Genie appear/disappear animation (Coons patch mesh with cubic Bezier S-curves)
• Wobbly window drag (spring physics on 4 corners)
• 4-side support (Top, Bottom, Left, Right, or Auto)
• Per-window settings, enable/disable each effect independently
• Backend-agnostic capture (you provide FBO callbacks)
• Built-in demo window with save/reset defaults, C API, DLL-ready

See ImGenie/readme.md for full documentation.
