bool  ibUseShadow = true 
)

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

Parameters
nameThe name to give the newly created mesh.
groupNameThe name of the resource group to assign the mesh to
controlPointBufferA 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
declarationVertexDeclaration describing the contents of the buffer. Note this declaration must only draw on buffer source 0!
widthSpecifies the width of the patch in control points. Note this parameter must greater than or equal to 3.
heightSpecifies the height of the patch in control points. Note this parameter must greater than or equal to 3.
uMaxSubdivisionLevel,vMaxSubdivisionLevelIf you want to manually set the top level of subdivision, do it here, otherwise let the system decide.
visibleSideDetermines which side of the patch (or both) triangles are generated for.
vbUsageVertex buffer usage flags. Recommend the default since vertex buffer should be static.
ibUsageIndex buffer usage flags. Recommend the default since index buffer should be dynamic to change levels but not readable.
vbUseShadowFlag to determine if a shadow buffer is generated for the vertex buffer. See HardwareBuffer for full details.
ibUseShadowFlag to determine if a shadow buffer is generated for the index buffer. See HardwareBuffer for full details.

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
nameThe name to give the resulting mesh
groupNameThe name of the resource group to assign the mesh to
planeThe orientation of the plane and distance from the origin
widthThe width of the plane in world coordinates
heightThe height of the plane in world coordinates
curvatureThe 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.
xsegmentsThe number of segments to the plane in the x direction
ysegmentsThe number of segments to the plane in the y direction
normalsIf true, normals are created perpendicular to the plane
numTexCoordSetsThe number of 2D texture coordinate sets created - by default the corners are created to be the corner of the texture.
uTileThe number of times the texture should be repeated in the u direction
vTileThe number of times the texture should be repeated in the v direction
upVectorThe 'Up' direction of the plane.
orientationThe orientation of the overall sphere that's used to create the illusion
vertexBufferUsageThe usage flag with which the vertex buffer for this plane will be created
indexBufferUsageThe usage flag with which the index buffer for this plane will be created
vertexShadowBufferIf 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
indexShadowBufferIf 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
ySegmentsToKeepThe 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.

vertexShadowBufferIf 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
indexShadowBufferIf 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
Resource* Ogre::MeshManager::createImpl ( const String name,
ResourceHandle  handle,
const String group,
bool  isManual,
ManualResourceLoader loader,
const NameValuePairList createParams 
)
protectedvirtual

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
nameThe unique name of the resource
groupThe name of the resource group to attach this new resource to
isManualIs 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.
loaderPointer 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.
createParamsIf 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
nameThe name to give the new mesh
groupNameThe name of the resource group to assign the mesh to
loaderManualResourceLoader 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
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.

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

virtual ResourceCreateOrRetrieveResult Ogre::ResourceManager::createOrRetrieve ( const String name,
const String group,
bool  isManual = false,

const NameValuePairList createParams = 0 
)
virtualinherited

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.

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

virtual ResourcePtr Ogre::ResourceManager::createResource ( const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList createParams = 0 
)
virtualinherited

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
nameThe unique name of the resource
groupThe name of the resource group to attach this new resource to
isManualIs 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.
loaderPointer 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.
createParamsIf any parameters are required to create an instance, they should be supplied here as name / value pairs

Definition at line 464 of file OgreResourceManager.h.

virtual const StringVector& Ogre::ResourceManager::getScriptPatterns ( void  ) const
virtualinherited

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.

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
filenameThe name of the .mesh file
groupNameThe name of the resource group to assign the mesh to
vertexBufferUsageThe usage flags with which the vertex buffer(s) will be created
indexBufferUsageThe usage flags with which the index buffer(s) created for this mesh will be created with.
vertexBufferShadowedIf true, the vertex buffers will be shadowed by system memory copies for faster read access
indexBufferShadowedIf true, the index buffers will be shadowed by system memory copies for faster read access

virtualinherited

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
nameThe name of the Resource
groupThe resource group to which this resource will belong
isManualIs the resource to be manually loaded? If so, you should provide a value for the loader parameter
loaderThe manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
loadParamsOptional pointer to a list of name/value pairs containing loading parameters for this type of resource.

virtual void Ogre::ResourceManager::parseScript ( DataStreamPtr stream,
const String groupName

virtualinherited

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
streamWeak reference to a data stream which is the source of the script
groupNameThe 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.

Implements Ogre::ScriptLoader.

Reimplemented in Ogre::MaterialManager, Ogre::CompositorManager, and Ogre::FontManager.

HardwareBuffer::Usage  indexBufferUsage = HardwareBuffer::HBU_STATIC_WRITE_ONLY,
bool  vertexBufferShadowed = true,
bool  indexBufferShadowed = true 
)

Prepares a mesh for loading from a file.

This does the IO in advance of the call to load().

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
filenameThe name of the .mesh file
groupNameThe name of the resource group to assign the mesh to
vertexBufferUsageThe usage flags with which the vertex buffer(s) will be created
indexBufferUsageThe usage flags with which the index buffer(s) created for this mesh will be created with.

const String group,
bool  isManual = false,

const NameValuePairList loadParams = 0,
bool  backgroundThread = false 
)
virtualinherited

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

Parameters
nameThe name of the Resource
groupThe resource group to which this resource will belong
isManualIs the resource to be manually loaded? If so, you should provide a value for the loader parameter
loaderThe manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
loadParamsOptional pointer to a list of name/value pairs containing loading parameters for this type of resource.
backgroundThreadOptional boolean which lets the load routine know if it is being run on the background resource loading thread
virtual void Ogre::ManualResourceLoader::prepareResource ( Resource resource)
virtualinherited

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
resourceThe resource which wishes to load

virtual void Ogre::ResourceManager::reloadAll ( bool  reloadableOnly = true)
virtualinherited

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
reloadableOnlyIf 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)
virtualinherited

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
reloadableOnlyIf true (the default), only reloads resources which can be subsequently automatically reloaded.
virtual void Ogre::ResourceManager::remove ( ResourcePtr r)
virtualinherited

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::remove ( const String name)
virtualinherited

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

Reimplemented in Ogre::CompositorManager.

virtual void Ogre::ResourceManager::removeImpl ( ResourcePtr res)
protectedvirtualinherited

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

virtual void Ogre::ResourceManager::removeUnreferencedResources ( bool  reloadableOnly = true)
virtualinherited

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
reloadableOnlyIf true (the default), only removes resources which can be subsequently automatically reloaded.
virtual bool Ogre::ResourceManager::resourceExists ( const String name)
virtualinherited

Returns whether the named resource exists in this manager.

Definition at line 357 of file OgreResourceManager.h.

virtual bool Ogre::ResourceManager::resourceExists ( ResourceHandle  handle)

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)
virtualinherited

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)
virtualinherited

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

protected

Utility method for tessellating 2D meshes.

virtual void Ogre::ResourceManager::unload ( const String name)
virtualinherited

Unloads a single resource by name.

Remarks
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

Resource::isReloadable for resource is reloadable.
virtual void Ogre::ResourceManager::unloadUnreferencedResources ( bool  reloadableOnly = true)
virtualinherited

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

Remarks
This method behaves like unloadAll, except that it only unloads 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, unload or reload that resource will cause dangerous pointer access. Use this function instead of unloadAll allows you avoid fail in those situations.
