Member Function Documentation

static osg::Uniform* makVrv::DtOsgEmissivityMapController::createLightRampUniform ( )

static

Creates a new light ramp uniform you can apply to a higher-up state set in OVERRIDE mode.

float[0..1]. The value specifies the amount of light currently in the scene - so smaller values turn on more lights.

static osg::Uniform* makVrv::DtOsgEmissivityMapController::getLightRampUniform ( osg::StateSet *  stateSet )

static

Access the uniform that controls how many emissive surfaces are active.

float[0..1]

virtual std::string makVrv::DtOsgEmissivityMapController::getEffectTypeCode ( ) const

inlinevirtual

The type code string for this effect.

Implements makVrv::DtOsgEffectTextureController.

virtual osg::Texture* makVrv::DtOsgEmissivityMapController::installEffectTexture ( osg::Texture *  baseTexture, int  texUnit, osg::StateSet *  stateSet, const osgDB::Options *  dbOptions, const FilenameMap &  possibleFilenames  )

virtual

Install the normal map texture + shaders on a state set.

Reimplemented from makVrv::DtOsgEffectTextureController.

virtual bool makVrv::DtOsgEmissivityMapController::generateShaders ( int  baseUnit, int  effectUnit, osg::Texture *  tex, osg::StateSet *  stateSet, const std::string &  baseTextureName  )

virtual

Generates shaders for a stateset if required by this effect.

Reimplemented from makVrv::DtOsgEffectTextureController.
