Detailed Description

The AbsolutePixelCountLodStrategy class LOD strategy that works like ScreenRatioPixelCountLodStrategy, but in range [-width * height;0] instead of [-1.0;0.0].

Because this strategy heavily depends on target resolution, it is strongly recommended that you use ScreenRatioPixelCountLodStrategy instead.

Constructor & Destructor Documentation

Ogre::AbsolutePixelCountLodStrategy::AbsolutePixelCountLodStrategy ( )

Default constructor.

static AbsolutePixelCountLodStrategy& Ogre::AbsolutePixelCountLodStrategy::getSingleton ( )

static

Override standard Singleton retrieval.

Remarks: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

static AbsolutePixelCountLodStrategy* Ogre::AbsolutePixelCountLodStrategy::getSingletonPtr ( )
