Abstract

• This will generate an EGLContext for the thread that draws with the Android Plugin.
• The generated EGLContext shares Unity's EGLContext.
• The Texture target passed by Unity can be TEXTURE_2D or TEXTUER_EXTERNAL_OES.
  • In the verification environment,
    • the target in the emulator is TEXTUER_EXTERNAL_OES
    • the target in the device is TEXTURE_2D
• If the target is TEXTURE_2D, draw it on the offscreen texture and then copy it to the Unity texture.
• If the target is TEXTUER_EXTERNAL_OES, draw directly on the Unity texture.
