I would like to render an opengles surface half the size of the actual resolution (for example for the high resolution of the n97)
So i would like to render to a surface of 320x180 and flush it to an eglSurface of 640x360 of the n97.
All examples of opengles i have used so far use the complete window and changing the viewport resizes the output. Which function must i use to blit the result to the Symbian Window? I have used win32 blitting for my games before and this has been accomplished. I cannot find the Symbian equivalent, and i do no know how to make opengles render to a seperate buffer instead of to the bound window.
How can this be accomplished?
