TL;DR;
- Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- Refer to 'opengl_example' to understand how the library is setup, it is the simplest one.
- Refer to 'opengl2_example' to LEARN how the library is setup, it is the simplest one.
The other examples requires more boilerplate and are harder to read.
- If you are using OpenGL in your application, probably use an opengl3_xxx backend.
Mixing old fixed pipeline OpenGL2 and programmable pipeline OpenGL3+ isn't well supported by drivers.
- If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
to your project and use them unmodified.
- If you have your own engine, you probably want to start from 'opengl_example' and adapt it to
- If you have your own engine, you probably want to start from one of the OpenGL example and adapt it to
your engine, but you can read the other examples as well.

At 60 FPS your experience should be pleasant. Consider that OS mouse cursors are typically drawn through
a specific hardware accelerated route and may feel smoother than other GPU rendered contents. You may
experiment with the io.MouseDrawCursor flag to request ImGui to draw a mouse cursor itself, to visualize
the lag between an hardware cursor and a software cursor. It might be beneficial to the user experience
the lag between a hardware cursor and a software cursor. It might be beneficial to the user experience
to switch to a software rendered cursor when an interactive drag is in progress.
Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering),
leaving you with no option but sadness/anger (Intel GPU drivers were reported as such).
opengl_example/
OpenGL example, using GLFW + fixed pipeline.
This is simple and should work for all OpenGL enabled applications.
Prefer following this example to learn how ImGui works!
(You can use this code in a GL3/GL4 context but make sure you disable the programmable pipeline
by calling "glUseProgram(0)" before ImGui::Render.)

opengl3_example/
OpenGL example, using GLFW/GL3W + programmable pipeline.
GLFW + OpenGL example (programmable pipeline, binding modern functions with GL3W).
This uses more modern OpenGL calls and custom shaders. It's more messy.
