Detailed Description

Strategy for determining level of detail.

Remarks

Generally, to create a new LOD strategy, all of the following will need to be implemented: getValueImpl, getBaseValue, transformBias, getIndex, sort, and isSorted. In addition, transformUserValue may be overridden.

sort()

static void Ogre::LodStrategy::sort ( v1::Mesh::MeshLodUsageList &  meshLodUsageList )

static

Sort mesh LOD usage list from greatest to least detail.

transformBias()

virtual Real Ogre::LodStrategy::transformBias ( Real  factor ) const

pure virtual

Transform LOD bias so it only needs to be multiplied by the LOD value.

Implemented in Ogre::DistanceLodStrategyBase, and Ogre::PixelCountLodStrategyBase.

transformUserValue()

virtual Real Ogre::LodStrategy::transformUserValue ( Real  userValue ) const

virtual

Transform user supplied value to internal value.

Remarks

By default, performs no transformation.

Do not throw exceptions for invalid values here, as the LOD strategy may be changed such that the values become valid.

Reimplemented in Ogre::DistanceLodStrategyBase, and Ogre::PixelCountLodStrategyBase.
