		unsigned int	textureObject
	)		const

virtual

Check if we have already added a texture object to our list of textures object by graphics context if we have already added then return true.

virtual bool makVrv::DtIndirectTextureResidencyManager::addTextureToGCMapIfNecessary	(	const osg::GraphicsContext *	graphicsContext,
		unsigned int	textureObject
	)		const

virtual

Add a texture object to our list of texture objects by graphics context, only if needed.

virtual void makVrv::DtIndirectTextureResidencyManager::makeTexturesResidentIfNeeded ( const osg::GraphicsContext * graphicsContext ) const

virtual

makes textures ready for bindless.

virtual void makVrv::DtIndirectTextureResidencyManager::releaseGLObjects ( osg::State * state ) const

virtual

release internal gl data.

virtual void makVrv::DtIndirectTextureResidencyManager::releaseGLObjects ( const std::set< unsigned int > & textureObjectSetToUnload ) const

virtual

unload given textures (e.g. that the models refer to) (called only for a texture processor for the gt models (for the layer/entity grid) for gs the textures get deleted via the deletion of the texture processor using the releaseGLObjects(osg::State* state) variant above

virtual void makVrv::DtIndirectTextureResidencyManager::slot_windowToBeDestroyed ( DtWindow * window )

virtual

handle window closing (context destroyed)

		const osg::GraphicsContext *	graphicsContext
	)		const

virtual

Checks to see if the given texture id is used in any other context besides the given one.

		unsigned int	textureObject
	)		const

protectedvirtual

internal. Add a texture object to our list of texture objects by graphics context

	)		const

protectedvirtual

internal. collect any (new) textures we haven't seen yet for this graphics context (for non shared context ids)

protectedvirtual

internal. collect any (new) textures we haven't seen yet for this graphics context (for non shared context ids), and make them resident
