I need to apply some pixel shaders to a bitmap (using OpenGL) and send result to server. Rendering is supposed to be made in background so I can’t create GLSurfaceView for this purpose. So my question is: is it possible to make OpenGL rendering on Android without using GLSurfaceView? Like rendering directly to bitmap, or canvas or some sort of buffer/array? Or may by it is possible to use some kind of dummy GLSurfaceView?
This SO post contains a link to an anddev post. A bit downwards, somebody created a
PixelBufferclass that reuses theGLSurfaceView.Rendererinterface, but apart from that, only EGL.
