Common OpenGLES Framework For Embedded and Emulated desktop
COFFEE is a common platform to test OpenGLES application on embedded SoC EVK and PC desktop.
For OpenGLES emulation, I use Google ANGLE for supporting Windows/Linux/MacOS.
Currently, EGL backend for embedded SoC hasn't been implemented yet, and only x11 would be supported.
This framework is to use on embedded Linux BSP, such as Yocto so that it won't depend on external libraries, unique build system.
Some useful features for OpenGLES are provided by ANGLE. Also, a fundamental matrix and model related functions are provided by COFFEE utils.
The COFFEE framework uses gcc for Linux and MacOS, and VisualStudio 2017 for Windows.
The framework also uses cmake build system for both embedded and desktop environment. (Not ninja, which is required by ANGLE)
libEGL and libGLESv2 are required to build on embedded EVK. Please check it with the SDK which SoC vendor would provide.
SoC vendor would support different window systems, such as frame buffer, Wayland, and DRM/KMS.
You need to check which backends are supported by SDK.
(E.g. RPi BSP supports x11, but libEGL supports only framebuffer(DISPMANX), it would be overlayed on x11 Window)
Please source setup.sh before running cmake.
COFFEE_ROOT environment variable must be set to build.
$ . ./setup.sh
$ mkdir build && cd build
$ cmake ..
$ make
All assets in each sample programs are copied to build directory.
COFFEE_ROOT environment variables must be set to run cmake and VS2017.
I tested CMAKE-GUI 3.14.0-rc2 with targeting x64/VS2017 to generate COFFEE.sln
VS2017 should build all sample binaries with the solution file.
- Add window backend for embedded EVB
- RPi DISPMANX support
- Linux Wayland support
- Linux DRM/KMS support
- Clean definitions in CMakeLists.txt
- Add material/lighting support to the model viewer
- Add mtl material and texture support
