I am not too familiar with how GL works. Is the performance gain happen in writing to the screen or doing the image manipulation or BOTH. I mean I know I can convert a bitmap to a texture and put it on the GL surface. Most of my code is done using canvas to draw to off screen bitmaps before i finally draw the composite image to the screen.
Do I have to convert all that to GL textures or can I keep all the bitmap work and convert the final image to a texture to be drawn to the GL surface. If I have to convert it all to the textures and draw to the textures, will there be any performance gain by just drawing the final image to the GL surface but to the rest using Canvas?
