emulating getQueryObjectuiv

For an port of a opengl software i need to reach the functionallity of getQueryObjectuiv.

is there a chance, to do such an occlution check with opengl es?

No, query objects are not part of OpenGL ES or any released extension for it.

Ok. I know, because i found nothing about such an extension.Â

So do you see a chance to reimplement the same in an other way?

No, at least not without being extremely slow. What is the occlusion query used for?

It is used for identifying not visible octrees. Application is doing heavy geometry calculations. Identifying these trees will cause, that they are not updated some frames.
