Dear ImGui is highly portable and only requires a few things to run and render. |
|
|
|
|
- Providing mouse/keyboard inputs |
|
|
|
|
- Load the font atlas texture into graphics memory |
|
|
|
|
- Providing a render function to render indexed textured triangles |
|
|
|
|
- Optional: clipboard support, mouse cursor supports, Windows IME support, etc. |

So this is essentially what those examples are doing + the obligatory cruft for portability. |

ImGui has zero frame of lag for most behaviors and one frame of lag for some behaviors. |
