Member Function Documentation

void Ogre::MeshManager::_initialise ( void )

Initialises the manager, only to be called by OGRE internally.

virtual void Ogre::ResourceManager::_notifyResourceLoaded ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been loaded.

virtual void Ogre::ResourceManager::_notifyResourceTouched ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been 'touched', i.e.

used.

virtual void Ogre::ResourceManager::_notifyResourceUnloaded ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been unloaded.

virtual void Ogre::ResourceManager::addImpl ( ResourcePtr & res ) [protected, virtual, inherited]

Add a newly created resource to the manager (note weak reference).

virtual void Ogre::ResourceManager::checkUsage ( void ) [protected, virtual, inherited]

Checks memory usage and pages out if required.

virtual ResourcePtr Ogre::ResourceManager::create	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	createParams = `0`
	)			`[virtual, inherited]`

Creates a new blank resource, but does not immediately load it.

Remarks:: Resource managers handle disparate types of resources, so if you want to get at the detailed interface of this resource, you'll have to cast the result to the subclass you know you're creating.

Parameters:

	name	The unique name of the resource
	group	The name of the resource group to attach this new resource to
	isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
	loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
	createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs

PatchMeshPtr Ogre::MeshManager::createBezierPatch	(	const String &	name,
		const String &	groupName,
		void *	controlPointBuffer,
		VertexDeclaration *	declaration,
		size_t	width,
		size_t	height,
		size_t	uMaxSubdivisionLevel = `PatchSurface::AUTO_LEVEL`,
		size_t	vMaxSubdivisionLevel = `PatchSurface::AUTO_LEVEL`,
		PatchSurface::VisibleSide	visibleSide = `PatchSurface::VS_FRONT`,
		HardwareBuffer::Usage	vbUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		HardwareBuffer::Usage	ibUsage = `HardwareBuffer::HBU_DYNAMIC_WRITE_ONLY`,
		bool	vbUseShadow = `true`,
		bool	ibUseShadow = `true`
	)

Creates a Bezier patch based on an array of control vertices.

Parameters:

	name	The name to give the newly created mesh.
	groupName	The name of the resource group to assign the mesh to
	controlPointBuffer	A pointer to a buffer containing the vertex data which defines control points of the curves rather than actual vertices. Note that you are expected to provide not just position information, but potentially normals and texture coordinates too. The format of the buffer is defined in the VertexDeclaration parameter
	declaration	VertexDeclaration describing the contents of the buffer. Note this declaration must _only_ draw on buffer source 0!
	width	Specifies the width of the patch in control points. Note this parameter must greater than or equal to 3.
	height	Specifies the height of the patch in control points. Note this parameter must greater than or equal to 3.
	uMaxSubdivisionLevel,vMaxSubdivisionLevel	If you want to manually set the top level of subdivision, do it here, otherwise let the system decide.
	visibleSide	Determines which side of the patch (or both) triangles are generated for.
	vbUsage	Vertex buffer usage flags. Recommend the default since vertex buffer should be static.
	ibUsage	Index buffer usage flags. Recommend the default since index buffer should be dynamic to change levels but not readable.
	vbUseShadow	Flag to determine if a shadow buffer is generated for the vertex buffer. See HardwareBuffer for full details.
	ibUseShadow	Flag to determine if a shadow buffer is generated for the index buffer. See HardwareBuffer for full details.

		const String &	groupName,
		const Plane &	plane,
		Real	width,
		Real	height,
		Real	curvature,

		bool	vertexShadowBuffer = `true`,
		bool	indexShadowBuffer = `true`,
		int	ySegmentsToKeep = `-1`
	)

Creates a plane, which because of it's texture coordinates looks like a curved surface, useful for skies in a skybox.

Parameters:

	name	The name to give the resulting mesh
	groupName	The name of the resource group to assign the mesh to
	plane	The orientation of the plane and distance from the origin
	width	The width of the plane in world coordinates
	height	The height of the plane in world coordinates
	curvature	The curvature of the plane. Good values are between 2 and 65. Higher values are more curved leading to a smoother effect, lower values are less curved meaning more distortion at the horizons but a better distance effect.
	xsegments	The number of segments to the plane in the x direction
	ysegments	The number of segments to the plane in the y direction
	normals	If true, normals are created perpendicular to the plane
	numTexCoordSets	The number of 2D texture coordinate sets created - by default the corners are created to be the corner of the texture.
	uTile	The number of times the texture should be repeated in the u direction
	vTile	The number of times the texture should be repeated in the v direction
	upVector	The 'Up' direction of the plane.
	orientation	The orientation of the overall sphere that's used to create the illusion
	vertexBufferUsage	The usage flag with which the vertex buffer for this plane will be created
	indexBufferUsage	The usage flag with which the index buffer for this plane will be created
	vertexShadowBuffer	If this flag is set to true, the vertex buffer will be created with a system memory shadow buffer, allowing you to read it back more efficiently than if it is in hardware
	indexShadowBuffer	If this flag is set to true, the index buffer will be created with a system memory shadow buffer, allowing you to read it back more efficiently than if it is in hardware
	ySegmentsToKeep	The number of segments from the top of the dome downwards to keep. -1 keeps all of them. This can save fillrate if you cannot see much of the sky lower down.

Resource* Ogre::MeshManager::createImpl	(	const String &	name,
		ResourceHandle	handle,
		const String &	group,
		bool	isManual,
		ManualResourceLoader *	loader,
		const NameValuePairList *	createParams
	)			`[protected, virtual]`

Create a new resource instance compatible with this manager (no custom parameters are populated at this point).

Remarks:: Subclasses must override this method and create a subclass of Resource.

Parameters:

	name	The unique name of the resource
	group	The name of the resource group to attach this new resource to
	isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
	loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
	createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs. These do not need to be set on the instance (handled elsewhere), just used if required to differentiate which concrete class is created.

Implements Ogre::ResourceManager.

MeshPtr Ogre::MeshManager::createManual	(	const String &	name,
		const String &	groupName,
		ManualResourceLoader *	loader = `0`
	)

Creates a new Mesh specifically for manual definition rather than loading from an object file.

Remarks:: Note that once you've defined your mesh, you must call Mesh::_setBounds and Mesh::_setBoundingRadius in order to define the bounds of your mesh. In previous versions of OGRE you could call Mesh::_updateBounds, but OGRE's support of write-only vertex buffers makes this no longer appropriate.

Parameters:

	name	The name to give the new mesh
	groupName	The name of the resource group to assign the mesh to
	loader	ManualResourceLoader which will be called to load this mesh when the time comes. It is recommended that you populate this field in order that the mesh can be rebuilt should the need arise

virtual ResourceCreateOrRetrieveResult Ogre::ResourceManager::createOrRetrieve	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	createParams = `0`
	)			`[virtual, inherited]`

Create a new resource, or retrieve an existing one with the same name if it already exists.

Remarks:: This method performs the same task as calling getByName() followed by create() if that returns null. The advantage is that it does it in one call so there are no race conditions if using multiple threads that could cause getByName() to return null, but create() to fail because another thread created a resource in between.

See also:: ResourceManager::create; ResourceManager::getByName

Returns:: A pair, the first element being the pointer, and the second being an indicator specifying whether the resource was newly created.

ResourceCreateOrRetrieveResult Ogre::MeshManager::createOrRetrieve	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	params = `0`,
		HardwareBuffer::Usage	vertexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		HardwareBuffer::Usage	indexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		bool	vertexBufferShadowed = `true`,
		bool	indexBufferShadowed = `true`
	)

Create a new mesh, or retrieve an existing one with the same name if it already exists.

Parameters:

	vertexBufferUsage	The usage flags with which the vertex buffer(s) will be created
	indexBufferUsage	The usage flags with which the index buffer(s) created for this mesh will be created with.
	vertexBufferShadowed	If true, the vertex buffers will be shadowed by system memory copies for faster read access

Gets the file patterns which should be used to find scripts for this ResourceManager.

Remarks:: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

: This method lets you determine the file pattern which will be used to identify scripts intended for this manager.

Returns:: A list of file patterns, in the order they should be searched in.

static MeshManager& Ogre::MeshManager::getSingleton ( void ) [static]

Override standard Singleton retrieval.

Remarks:: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from Ogre::Singleton< MeshManager >.

		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	loadParams = `0`,
		bool	backgroundThread = `false`
	)			`[virtual, inherited]`

Generic load method, used to create a Resource specific to this ResourceManager without using one of the specialised 'load' methods (containing per-Resource-type parameters).

Parameters:

	name	The name of the Resource
	group	The resource group to which this resource will belong
	isManual	Is the resource to be manually loaded? If so, you should provide a value for the loader parameter
	loader	The manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
	loadParams	Optional pointer to a list of name/value pairs containing loading parameters for this type of resource.
	backgroundThread	Optional boolean which lets the load routine know if it is being run on the background resource loading thread

MeshPtr Ogre::MeshManager::load	(	const String &	filename,
		const String &	groupName,
		HardwareBuffer::Usage	vertexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		HardwareBuffer::Usage	indexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		bool	vertexBufferShadowed = `true`,
		bool	indexBufferShadowed = `true`
	)

Loads a mesh from a file, making it immediately available for use.

Note:: If the model has already been created (prepared or loaded), the existing instance will be returned.

Remarks:: Ogre loads model files from it's own proprietary format called .mesh. This is because having a single file format is better for runtime performance, and we also have control over pre-processed data (such as collision boxes, LOD reductions etc).

Parameters:

	filename	The name of the .mesh file
	groupName	The name of the resource group to assign the mesh to
	vertexBufferUsage	The usage flags with which the vertex buffer(s) will be created

virtual void Ogre::ResourceManager::parseScript	(	DataStreamPtr &	stream,
		const String &	groupName
	)			`[virtual, inherited]`

Parse the definition of a set of resources from a script file.

Remarks:: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

Parameters:

	stream	Weak reference to a data stream which is the source of the script
	groupName	The name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it.

virtual void Ogre::ManualResourceLoader::prepareResource ( Resource * resource ) [virtual, inherited]

Called when a resource wishes to load.

Note that this could get called in a background thread even in just a semithreaded ogre (OGRE_THREAD_SUPPORT==2). Thus, you must not access the rendersystem from this callback. Do that stuff in loadResource.

Parameters:

resource

The resource which wishes to load

Definition at line 524 of file OgreResource.h.

virtual void Ogre::ResourceManager::reloadAll ( bool reloadableOnly = true ) [virtual, inherited]

Caused all currently loaded resources to be reloaded.

Remarks:: All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.

Parameters:

reloadableOnly

If true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.

See also:: Resource::isReloadable for resource is reloadable.

virtual void Ogre::ResourceManager::reloadUnreferencedResources ( bool reloadableOnly = true ) [virtual, inherited]

Caused all currently loaded but not referenced by any other object resources to be reloaded.

Remarks:: This method behaves like reloadAll, except that it only reloads resources which are not in use, i.e. not referenced by other objects.

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of reloadAll allows you avoid fail in those situations.

Parameters:

reloadableOnly

If true (the default), only reloads resources which can be subsequently automatically reloaded.

virtual void Ogre::ResourceManager::remove ( ResourceHandle handle ) [virtual, inherited]

Remove a single resource by handle.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::remove ( const String & name ) [virtual, inherited]

Remove a single resource by name.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::remove ( ResourcePtr & r ) [virtual, inherited]

Remove a single resource.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::removeAll ( void ) [virtual, inherited]

Removes all resources.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to these resources, they will persist until they have been finished with; however to all intents and purposes the resources no longer exist and will get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

Reimplemented in Ogre::CompositorManager.

virtual void Ogre::ResourceManager::removeImpl ( ResourcePtr & res ) [protected, virtual, inherited]

Remove a resource from this manager; remove it from the lists.

virtual void Ogre::ResourceManager::removeUnreferencedResources ( bool reloadableOnly = true ) [virtual, inherited]

Remove all resources which are not referenced by any other object.

Remarks:: This method behaves like removeAll, except that it only removes resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, remove or reload that resource will cause dangerous pointer access. Use this function instead of removeAll allows you avoid fail in those situations.

Parameters:

reloadableOnly

If true (the default), only removes resources which can be subsequently automatically reloaded.

void Ogre::MeshManager::setListener ( MeshSerializerListener * listener )

Sets the listener used to control mesh loading through the serializer.

virtual void Ogre::ResourceManager::setMemoryBudget ( size_t bytes ) [virtual, inherited]

Set a limit on the amount of memory this resource handler may use.

Remarks:: If, when asked to load a new resource, the manager believes it will exceed this memory budget, it will temporarily unload a resource to make room for the new one. This unloading is not permanent and the Resource is not destroyed; it simply needs to be reloaded when next used.

void Ogre::MeshManager::setPrepareAllMeshesForShadowVolumes ( bool enable )

Tells the mesh manager that all future meshes should prepare themselves for shadow volumes on loading.

virtual void Ogre::ResourceManager::setVerbose ( bool v ) [virtual, inherited]

Sets whether this manager and its resources habitually produce log output.
