Detailed Description

Installs and control emissivity mapping effects.

Constructor & Destructor Documentation

makVrv::DtOsgEmissivityMapController::DtOsgEmissivityMapController ( const DtOsgFileCache & fileCache )

CTOR.

virtual makVrv::DtOsgEmissivityMapController::~DtOsgEmissivityMapController ( )

virtual

DTOR.

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

virtual

Install the effect texture from a list of possible effect texture names.

Parameters

baseTexture	The pointer of the base texture.
baseTexUnit	The texture unit of the base texture.
stateSet	The osg::StateSet that the base texture resides in.
dbOptions	The options passed from osg.
possibleFilenames	A list of of possible effect texture names.

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

virtual

install shaders for a stateset if required by this effect.
