This manager manages the lifetime of the actual gl texture objects (gl unsigned ints) in the indirect rendering module.

These texture objects are based on (keyed on) DtIndirectTexturePrototype.

See DtIndirectTexturePrototype and DtIndirectTexturePrototypeManager for detailed explanation of the texturing system.

Member Function Documentation

static DtIndirectGlTextureObjectManager& makVrv::DtIndirectGlTextureObjectManager::instance ( DtDe & de )

static

Access the singleton instance.

DtIndirectGlTextureObjectManager& makVrv::DtIndirectGlTextureObjectManager::operator= ( const DtIndirectGlTextureObjectManager & rhs )

delete

not allowed

virtual DtIndirectGlTextureObjectResult makVrv::DtIndirectGlTextureObjectManager::getOrCreate	(	const DtIndirectTexturePrototype *	vrvTexture,
		int	textureLimitStrategy
	)

virtual

Get or create a texture keyed on the given vrv texture If not present, will make a texture object. If present, will return the texture object. Will use the vrv texture's image to fill its mip maps.

Parameters

vrvTexture	The DtIndirectTexturePrototype template to create the texture from
limit	strategy to use (there's only 2 right now, entity and terrain)

virtual DtIndirectGlTextureObject* makVrv::DtIndirectGlTextureObjectManager::get ( const DtIndirectTexturePrototype * vrvTexture )

virtual

same as above, but will not create, if not present. will return 0 in this case

virtual bool makVrv::DtIndirectGlTextureObjectManager::has ( unsigned int textureId ) const

virtual

whether this exists

virtual bool makVrv::DtIndirectGlTextureObjectManager::removeEntry ( DtIndirectGlTextureObject * indirectGlTextureObject )

virtual

This is called via DtIndirectGlTextureObject, when it's user count goes to zero Higher up, it is actually called indirectly called via DtGpuCulling::releaseGlObjects with a call to remove itself as the user of the DtIndirectGlTextureObject.

virtual unsigned int makVrv::DtIndirectGlTextureObjectManager::outOfMemoryTextureId ( void ) const

virtual

texture id of the texture used when we are out of memory

virtual DtVector2<int> makVrv::DtIndirectGlTextureObjectManager::seenImageSize ( const std::string & imageFileAbsolutePath ) const

virtual

get the size of the image that's been seen so far useful to track all images seen, because images can be nulled out after processing and deleted by the ref counting of the caching in DtOsgFileCache

virtual void makVrv::DtIndirectGlTextureObjectManager::run ( unsigned int frameNumber )

virtual

This will actually just run once for each gc, each frame.

virtual std::unordered_set<DtIndirectGlTextureObject*>& makVrv::DtIndirectGlTextureObjectManager::texturesSet ( void )

virtual

accessor

virtual void makVrv::DtIndirectGlTextureObjectManager::printStatsWhenNoWindows ( void )

virtual

Used for debugging This is used for debugging for when we removed all windows There should be no textures with resident handles. Furthermore, textures with no resident handles in any context, should have been deleted.

create compressed 2d image. this is the path used majority of the time

protectedvirtual

create compressed 2d image. (e.g. sfx pods)

virtual unsigned int makVrv::DtIndirectGlTextureObjectManager::createGlTexture2dArray ( const DtIndirectTexturePrototype * vrvTexture ) const

protectedvirtual

create compressed 2d image. (sfx textures are sometimes 2d arrays)

virtual unsigned int makVrv::DtIndirectGlTextureObjectManager::createGlTexture3D ( const DtIndirectTexturePrototype * vrvTexture ) const

protectedvirtual

create uncompressed 3d texture.

virtual void makVrv::DtIndirectGlTextureObjectManager::setupWrapFilteringAndAniso	(	unsigned int	textureId,
		const DtIndirectTexturePrototype *	vrvTexture
	)		const

protectedvirtual

set up texture parameters into texture id from the vrv texture

virtual bool makVrv::DtIndirectGlTextureObjectManager::textureWillPutMemoryAboveCutoff ( int sizeOfTextureInBytes ) const

protectedvirtual

whether making this texture will put the used memory above cutoff
