graphics - Creating OFF SCREEN surface using Open GL ES 2.0 -

-

i want draw scenario using opengl es 2.0 creating user defined surface during egl initialization. can use drawn surface further processing.

i think have use eglcreatepixmapsurface(), not sure usage. kindly help?

most platforms have no support pixmaps whatsoever. may able create 1 egl, if os not know is, useless.

on android, off-screen surfaces must created explained here.

fbos best solution on platforms, fbos further processing opengl es. reading image typically requires using glreadpixels() slow on platforms.

i have collection of articles here show how use fbos on platforms.
