## Detailed Description

Abstract base class for level of detail strategy based on pixel count approximations from bounding sphere projection.

## Constructor & Destructor Documentation

## PixelCountLodStrategyBase()

Ogre::PixelCountLodStrategyBase::PixelCountLodStrategyBase | ( | const String & | name | ) |

Default constructor.

## Member Function Documentation

## getBaseValue()

Real Ogre::PixelCountLodStrategyBase::getBaseValue | ( |  | ) | const

override virtual

Get the value of the first (highest) level of detail.

Implements Ogre::LodStrategy.

## transformBias()

Real Ogre::PixelCountLodStrategyBase::transformBias | ( | Real | factor | ) | const

override virtual

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

Implements Ogre::LodStrategy.

## getIndex() [1/2]

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

override virtual

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

override virtual

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

override virtual

Sort mesh LOD usage list from greatest to least detail.

Implements Ogre::LodStrategy.

## isSorted()

bool Ogre::PixelCountLodStrategyBase::isSorted | ( | const Mesh::LodValueList & | values | ) | const

override virtual

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

Implements Ogre::LodStrategy.
