It is relevant, the thread started talking about how async render impacts EvasGL usage. My concerns will be the concerns of anyone trying to use some random 3D rendering library package with EFL. EFL really only does 2D, it has no good support for 3D apps, it needs a decent 3D render engine. That's why I'm trying to get EFL and Irrlicht to work well together. I think Irrlicht is a good match for EFL. But my concern is not Irrlicht specific, it's a general concern for other people using 3D libraries as well. Or even heavy GL users. I'll try that when I next get time to play with it. I think that still leaves the problem of the non render calls now likely to be in the wrong thread. Setup stuff is likely to be done in the main thread. General tweakage of 3D engine stuff is likely done outside of the render callback. For example, your game decides it's time to add some new 3D object, that decision is likely not done in the render callback. This sort of thing should be well documented, and good examples of how to deal with async EvasGL rendering, third party GL libraries, and heavy GL usage. Hmm, this might be why the ELM GL examples are now broken, which means "told you so". :-P -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
