LearnOpenGLES

This project is mainly based on the code of LearnOpenGL and adopted some cross-platform features of Vulkan.
All rendering code is front-end and back-end separated. The gui or window is running on the front-end, and the opengles render is running on the backend. The front-end code is only for presentation, and the back-end OpenGLES is only for rendering computation regardless of the GUI. You can choose the display surface you like, such as GLFW3, xcb(X11), WIN32UI, and Qt. You just need to create a native window Handle (such as HWND and xcb_window_t), and give the window handle to the EGL to create a rendering surface. It is easily integrated into any front-end framework, and this project shows the examples of Qt (not using QOpengGLWidget).

Requirements

Supported System:

Now: Linux(Mainly) Android(Mainly) Windows(Partly) Planned supported: Mac IOS

Libraries and Tools

CMake: 3.14+ is recommended OpenGLES: 3.0+ Glm: 0.9.9+ Xcb & Xlib (Linux needs) GLFW3
OpenCV: 4.0+ (Some projects need) CUDA: 10.0+ (Some projects need) Qt: 5.12+ (Some projects need)

Compile & BUILD

For Linux/UNIX

If you don't have GLM, GLI, IMGUI, you need "git submodule update --init" first.

   git submodule update --init

Compile

    cmake ..
    make
    make install

The programs will be installed in the {PROJECT_DIR}/bin .

For Android

Use Android Studio to open the directory (./Android) Default ndk version 21.1.6352462 Android Sdk version 30

For Qt

    cmake .. -DBUILD_QtExamples=ON

For Windows

Compile

    cmake -G "Visual Studio 15 2017 Win64" -T host=x64 ..
    cmake --build . --config Release
    cmake --build . --config Release --target INSTALL

The programs will be installed in the {PROJECT_DIR}/Release .

PLANS

  1. Simple Examples (10%) (Only need OpenGLES)
