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()

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

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

Implements Ogre::LodStrategy.

◆ transformBias()

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

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

Implements Ogre::LodStrategy.

◆ getIndex() [1/2]

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

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

Implements Ogre::LodStrategy.

◆ getIndex() [2/2]

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

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

Implements Ogre::LodStrategy.

◆ sort()

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

Sort mesh LOD usage list from greatest to least detail.

Implements Ogre::LodStrategy.

◆ isSorted()

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

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

Implements Ogre::LodStrategy.

◆ transformUserValue()

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

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.

◆ getValue()

Real Ogre::LodStrategy::getValue ( const MovableObject movableObject,
const Camera camera 
) const
inherited

Compute the LOD value for a given movable object relative to a given camera.

◆ assertSorted()

void Ogre::LodStrategy::assertSorted ( const Mesh::LodValueList values) const
inherited

Assert that the LOD values are sorted from greatest detail to least detail.

◆ getName()

const String& Ogre::LodStrategy::getName ( void  ) const
inlineinherited

Get the name of this strategy.
