Visitor that locates effect textures and installs them into the scene graph. Run this prior to running the Shader Generator to pick up normal maps, reflectivity maps, specular maps, ambient occlusion maps, and emissivity maps.

virtual void makVrv::DtOsgEffectTextureVisitor::setDbOptions ( const osgDB::Options * options )

virtual

Set the database options.

virtual void makVrv::DtOsgEffectTextureVisitor::reset ( )

virtual

Resets the visitor to its initial state. If you plan to use the same instance more than once, call reset() before each use.

virtual unsigned makVrv::DtOsgEffectTextureVisitor::numEffectTexturesInstalled ( ) const

virtual

After visiting, call this to see how many effect textures the visitor installed. Calling reset() will reset this to zero.

protected

Non-virtual, called in the CTOR.

void makVrv::DtOsgEffectTextureVisitor::apply ( osg::StateSet * stateSet )

protected

scan a stateset and apply effect textures as necessary.

virtual bool makVrv::DtOsgEffectTextureVisitor::isEffectTexture	(	osg::Texture *	tex,

protectedvirtual

Checks whether a texture is an effect texture.

	)

protectedvirtual

Install the effect texture from the postfix way, it will try find the suffix texture in the texture layers in the stateSet itself.

Parameters

controller	The controller we are trying to apply.
baseTex	The pointer to the base texture.
baseTexUnit	The texture unit of the base texture.
stateSet	The osg::StateSet that the base texture resides in.

virtual bool makVrv::DtOsgEffectTextureVisitor::installPostfixEffectTexturesFromFileSystem	(	const DtOsgEffectTextureController *	controller,
		osg::Texture *	baseTex,
		int	baseTexUnit,
		osg::StateSet *	stateSet
	)

protectedvirtual

Install the effect texture from the postfix way, it will try find the suffix texture in the file system.

Parameters

controller	The controller we are trying to apply.
baseTex	The pointer to the base texture.
baseTexUnit	The texture unit of the base texture.
stateSet	The osg::StateSet that the base texture resides in.

virtual bool makVrv::DtOsgEffectTextureVisitor::checkForGlassMaterial ( osg::StateSet * stateSet )

protectedvirtual

Checks if the stateSet has any texture contains "GlassMat", if so, we treate this object as glass.

Returns: Return whether this we treate this object as glass.
