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
overridevirtual

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

Implements Ogre::LodStrategy.

◆ transformBias()

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

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

Implements Ogre::LodStrategy.

◆ transformUserValue()

Real Ogre::PixelCountLodStrategyBase::transformUserValue ( Real  userValue) const
inlineoverridevirtual

Transform user supplied value to internal value.

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

Reimplemented from Ogre::LodStrategy.
