c3-gl-generator

Python scripts to generate OpenGL ES and EGL bindings for the C3 language. This is especially useful for Android.

Features

• Generates C3 bindings from Khronos XML
• Supports EGL, OpenGL ES, OpenGL and extensions
• Generates:
  • Type aliases
  • Constants
  • Function pointer declarations
  • Runtime symbol loader

Platform Notes

Note: This project has been tested only on Android (AArch64/ARM64). Other platforms and architectures are untested and may require additional adjustments to compile correctly.

Usage

python c3_gl.py --api gles2 --ver 2.0 --out gl.c3l/gl.c3
python c3_egl.py --ext EGL_extension --out egl.c3l/egl.c3

Then copy gl.c3l and/or egl.c3l to YourProject/lib/

Before using any OpenGL/EGL functions in your code, you need to initialize the bindings:

gl::loadSymbols(egl::getProcAddress);
gl::loadSymbols(glfw::getProcAddress);

// Or manually using dynamic library loading
void* eglHandler = libc::dlopen("/system/lib64/libEGL.so", libc::RTLD_LAZY);
egl::getProcAddress = libc::dlsym(eglHandler, "eglGetProcAddress");

Example
