OGRE_AUTO_MUTEX | |
Class representing a Compositor object.
Compositors provide the means to flexibly "composite" the final rendering result from multiple scene renders and intermediate operations like rendering fullscreen quads. This makes it possible to apply postfilter effects, HDRI postprocessing, and shadow effects to a Viewport.

virtualinherited |
Prepares the resource for load, if it is not already.
One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.
backgroundThread | Whether this is occurring in a background thread |
|

Loads the resource, if it is not already.

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.
Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.
