Thomas, I just tested this using the glGetIntegerv method that takes an int array instead of a Buffer. It also returned 0 for me. So I dug into the source and found that the implementation of glGetIntegerv doesn't have a case for GL_MATRIX_MODE. And it sets the GL error to GL_INVALID_ENUM (1280). And sure enough, 1280 is returned by a call to glGetError right after the call to glGetIntegerv. So it looks like you can't get the GL_MATRIX_MODE that way on Android.
And upon further looking through the code I don't see anywhere that the matrixMode state variable is accessed. So I doubt that you'll have any luck getting it from the java API. If you control all of your OpenGL code you can work around this by using a wrapper to change GL state. It's not ideal, but it should work. That wrapper class could then be queried for the current matrix mode. -Anton On Mar 23, 7:39 am, tcassany <tcass...@betomorrow.com> wrote: > Hello, > > I just would to know how can I get the currentmatrixmode.
