Member Function Documentation

assemble()

void AppDemoSceneSuzanne::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.

Reimplemented from SLScene.

registerAssetsToLoad()

void AppDemoSceneSuzanne::registerAssetsToLoad ( SLAssetLoader &  al )

overridevirtual

All scene specific assets have to be registered for async loading in here.

All assets the should be loaded in parallel must be registered in here.

Remarks

All scene sspecific 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.
