Those are standalone ready-to-build applications to demonstrate ImGui.
|
||||
Binaries of some of those demos: http://www.miracleworld.net/imgui/binaries
|
||||
|
||||
Third party languages and frameworks bindings: https://github.com/ocornut/imgui/wiki/Links
|
||||
(languages: C, .net, rust, D, Python, Lua..)
|
||||
(frameworks: DX12, Vulkan, Cinder, OpenGLES, openFrameworks, Cocos2d-x, SFML, Flexium, NanoRT, Irrlicht..)
|
||||
(extras: RemoteImGui, ImWindow, imgui_wm..)
|
||||
|
||||
TL;DR;
|
||||
- Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
|
||||
- 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 one of the OpenGL example and adapt it to
|
||||
your engine, but you can read the other examples as well.
|
||||
|
||||
ImGui is highly portable and only requires a few things to run:
|
||||
- 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.
|
||||
|
||||
Unfortunately in 2016 it is still tedious to create and maintain portable build files using external
|
||||
libraries (the kind we're using here to create a window and render 3D triangles) without relying on
|
||||
third party software. For most examples here I choose to provide:
|
||||
- Makefiles for Linux/OSX
|
||||
- Batch files for Visual Studio 2008+
|
||||
- A .sln project file for Visual Studio 2010+
|
||||
Please let me know if they don't work with your setup!
|
||||
You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
|
||||
directly with a command-line compiler.
|
||||
|
||||
ImGui has zero frame of lag for most behaviors and one frame of lag for some behaviors.
|
||||
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 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).
|
||||
|
||||
opengl2_example/
|
||||
GLFW + OpenGL example (old fixed pipeline).
|
||||
This is simple to read. Prefer following this example to learn how ImGui works!
|
||||
(You might be able to 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/
|
||||
GLFW + OpenGL example (programmable pipeline, binding modern functions with GL3W).
|
||||
This uses more modern OpenGL calls and custom shaders. It's more messy.

# iOS / OSX example
|
||||
|
||||
## Introduction
|
||||
|
||||
This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/) to share mouse/keyboard on an iOS device.
|
||||
|
||||
It is a rather complex and messy example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui. **The opengl3_example/ should also work on OS X and is much simpler.** This is an integration for iOS with Synergy.
|
||||
|
||||
Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
|
||||
|
||||
## How to Use on iOS
|
||||
|
||||
* In Synergy, go to Preferences, and uncheck "Use SSL encryption"
|
||||
* Run the example app.
|
||||
* Tap the "servername" button in the corner
|
||||
* Enter the name or the IP of your synergy host
|
||||
* If you had previously connected to a server, you may need to kill and re-start the app.
|
||||
|
||||
## How to Build on OSX
|
||||
|
||||
* Make sure you have install `brew`, if not, please refer to [Homebrew Website](http://brew.sh)
|
||||
* Run the command: `brew install glfw3`
|
||||
* Double click `imguiex.xcodeproj` and select `imguiex-osx` scheme
|
||||
* Click `Run` button
|
||||
|
||||
## Notes and TODOs
|
||||
|
||||
Things that would be nice but I didn't get around to doing:
|
||||
|
||||
* iOS software keyboard not supported for text inputs
|
||||
* iOS hardware (bluetooth) keyboards not supported
|
||||
* Graceful disconnect/reconnect from uSynergy.
|
||||
* Copy/Paste not well-supported
|
||||
|
||||
## C++ on iOS / OSX
|
||||
|
||||
ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
|
||||
|
||||
Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
|
||||
|
||||
In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.

// ImGui SDL2 binding with OpenGL3

// In this binding, ImTextureID is used to store an OpenGL 'GLuint' texture identifier. Read the FAQ about ImTextureID in imgui.cpp.

// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
|

// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
|
||||
// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
