ushort Ogre::PixelCountLodStrategyBase::getIndex ( Real  value,
const Mesh::MeshLodUsageList meshLodUsageList 
) const
overridevirtual

Get the index of the LOD usage which applies to a given value.

Implements Ogre::LodStrategy.

◆ getIndex() [2/2]

ushort Ogre::PixelCountLodStrategyBase::getIndex ( Real  value,
const Material::LodValueList materialLodValueList 
) const
overridevirtual

Get the index of the LOD usage which applies to a given value.

Implements Ogre::LodStrategy.

◆ sort()

void Ogre::PixelCountLodStrategyBase::sort ( Mesh::MeshLodUsageList meshLodUsageList) const
overridevirtual

Sort mesh LOD usage list from greatest to least detail.

Implements Ogre::LodStrategy.

◆ isSorted()

bool Ogre::PixelCountLodStrategyBase::isSorted ( const Mesh::LodValueList values) const
overridevirtual

Determine if the LOD values are sorted from greatest detail to least detail.

Implements Ogre::LodStrategy.
