Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).

**Why the odd dual naming, "Dear ImGui" vs "ImGui"?**
The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.

See the FAQ in imgui.cpp for answers.
**How do you use Dear ImGui on a platform that may not have a mouse or keyboard?**
You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).
You can share your computer mouse seamlessly with your console/tablet/phone using [Synergy](http://synergy-project.org). This is the preferred solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC using Synergy 1.x. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui).
For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision.
**Can you create elaborate/serious tools with Dear ImGui?**
Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.

Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com).
I first discovered imgui principles at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple imgui implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it.
