How powerful is the real-time rendering UI that makes me excited after reading the introduction?

Today, I want to share with you an instant rendering UI implemented in C/C++ language - ImGUI, which implements almost all UI elements such as buttons, text, input boxes, tables, Radio/Check Boxes and lists, and gives people a refreshing feeling. It is also extremely easy to get started and learn. ImGUI not only provides cross-platform support, but also can cover the support of almost all compilers.

ImGui is designed to support rapid iteration and enable programmers to create content creation tools and visualization/debugging tools (as opposed to UIs for general end users). ImGui is particularly well suited for integration into game engines (for tools), real-time 3D applications, full-screen applications, embedded applications, or any application on a console platform where OS functionality is non-standard.

The core of ImGui is contained in some platform-independent files that you can easily compile in your application/engine. They are all files in the root directory of the repository (imgui*.cpp, imgui*.h). No specific build process is required. You can add the .cpp files to your existing project.

Various graphics APIs and rendering platforms are provided in the backends/ folder, and example applications are in the examples/ folder. Once you have set up Dear ImGui in your application, you can use it _anywhere_ in your program loop:

Currently, ImGui has 31.5K stars and 5.3K branches on github (github address: https://github.com/ocornut/imgui)

Code:

 ImGui::Text( "Hello, world %d" , 123);
 if (ImGui::Button( "Save" ))
 MySaveFunction();
 ImGui::InputText( "string" , buf, IM_ARRAYSIZE(buf));
 ImGui::SliderFloat( "float" , &f, 0.0f, 1.0f);

Running results:

In the issue, there is a collection of screenshots made by various people using imgui collected by ocornut:

There is a question on Zhihu: How do you evaluate imgui? One netizen answered: After reading the Readme, I want to pay money. Many programmers have also expressed their experience on it. Zhihu link address: https://www.zhihu.com/question/267602287
