Hi I have a layout with two fullscreen views on top of each other. The bottom view just shows a .png picture. The top view shows some OpenGL rendered graphics. When some translucent objects on the top view moves over a non-black area of the bottom view, blending is real bad - example1: blue in bottom view and translucent yellow/red (fire) in top view, turns out to be shiny green!?!) - example2: gray in bottom view and translucent yellow/red (fire) in top view, also turns out to be shiny green!?!) How can I improve??? Blending internally in the top view (OpenGL) works fine.
Selected code: Bottom view: Fields private Bitmap mBackgroundImage; private SurfaceHolder mSurfaceHolder; In view constructor: mSurfaceHolder = getHolder(); mBackgroundImage = BitmapFactory.decodeResource(res, R.drawable.mypic); In doDraw Canvas c = mSurfaceHolder.lockCanvas(null); c.drawBitmap(mBackgroundImage, 0, 0, null); Top view: Fields EGL10 mEgl; EGLDisplay mEglDisplay; EGLSurface mEglSurface; EGLConfig mEglConfig; EGLContext mEglContext; Initializing: int[] configSpec = { EGL10.EGL_RED_SIZE, 8, EGL10.EGL_GREEN_SIZE, 8, EGL10.EGL_BLUE_SIZE, 8, EGL10.EGL_ALPHA_SIZE, 8, EGL10.EGL_DEPTH_SIZE, 16, EGL10.EGL_NONE }; mEgl = (EGL10) EGLContext.getEGL(); mEglDisplay = mEgl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY); int[] version = new int[2]; mEgl.eglInitialize(mEglDisplay, version); EGLConfig[] configs = new EGLConfig[1]; int[] num_config = new int[1]; mEgl.eglChooseConfig(mEglDisplay, configSpec, configs, 1, num_config); mEglConfig = configs[0]; mEglContext = mEgl.eglCreateContext(mEglDisplay, mEglConfig, EGL10.EGL_NO_CONTEXT, null); mEglSurface = mEgl.eglCreateWindowSurface(mEglDisplay, mEglConfig, holder, null); mEgl.eglMakeCurrent(mEglDisplay, mEglSurface, mEglSurface, mEglContext); In doDraw: < do the OpenGL drawing > mEgl.eglSwapBuffers(mEglDisplay, mEglSurface); --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
