◆ assemble()

void AppDemoSceneJansUniverse::assemble	(	SLAssetManager *	am,
		SLSceneView *	sv
	)

overridevirtual

After parallel loading of the assets the scene gets assembled in here.

Remarks: All scene-specific assets have to be loaded async by overriding SLScene::registerAssetsToLoad and SLScene::assemble. Async loading and assembling means that it happens in a parallel thread and that in there are no OpenGL calls allowed. OpenGL calls are only allowed in the main thread. It is important that all object instantiations within SLScene::assemble do NOT call any OpenGL functions (gl*) because they happen in a parallel thread. All objects that get rendered have to do their initialization when they are used the first time during rendering in the main thread.
