imgui

Dear ImGui is a portable, renderer-agnostic GUI library for C++ that focuses on simplicity and productivity. It is specifically designed for programmers to create visualization, debug, and content creation tools rather than end-user interfaces. The library outputs optimized vertex buffers that can be rendered within any 3D pipeline, making it highly suitable for game engines, real-time 3D applications, and embedded systems. Key characteristics include: - Minimal state synchronization and low memory consumption. - No external dependencies; the core is self-contained in a few platform-agnostic files. - Renderer agnostic: it does not touch the GPU directly but provides draw call batches. - Extensive backend support for graphics APIs (DirectX, OpenGL, Vulkan, Metal, WebGPU) and platforms (Win32, SDL, GLFW, Android, OSX). - Broad ecosystem of third-party language bindings and extensions for features like plotting (ImPlot) and node editors.
