Re: [android-developers] Re: GL10 access from outside of the rendering thread ...

Wait, what? Are you asking the question just to prove a point? I am on the Android team and I'm trying to help you. Could you just please be more explicit about how you tried to achieve what you wanted and how you ended up doing it in the end? (Since apparently you found a way.)

Any context value you get from onDrawFrame is only useful within that call stack.  I knew this before asking the question.  I just wanted to establish the level of support available to those I have financial responsibilities to and thus get a little leeway in my scheduling.  I've already been banned from this site using different email addresses for asking similar questions, and I suspect this will be the end of the discussion (if this is seen at all).  It IS possible to do this on Android by circumventing the tools Gooble/Android provides, just for the record.  Good luck to all in their efforts!

Hello,

I am optimizing an OpenGL-based application ported from that other
major mobile OS and find that I cannot successfully access the GL
context from anything other than the rendering thread of
GLSurfaceView.  What I CAN do on other platforms is upload my single
(and large) texture to GL prior to needing to render the texture
itself.  This is a 640x480 8-bit RGB texture that takes some time to
upload to the chip and needs to be done every time I realize a new
frame of animation from the background system memory buffer.  I'm sure
you can appreciate the savings in execution time if I can perform this
upload from another thread when I have nothing left to do but wait for
GLSurfaceView's rendering thread to call me.  All is synchronized
safely as evidenced by the successful release of this software using
this very same technique on that-other-platform-that-shall-not-be
named.  Things are very smooth and zippy on that platform, but Android
currently suffers by comparison.  Is there any way to do this?


Thanks

Glenn
