## Detailed Description

Resource holding data about 3D mesh.

Remarks
  This class holds the data used to represent a discrete 3-dimensional object. Mesh data usually contains more than just vertices and triangle information; it also includes references to materials (and the faces which use them), level-of-detail reduction information, convex hull definition, skeleton/bones information, keyframe animation etc. However, it is important to note the emphasis on the word 'discrete' here. This class does not cover the large-scale sprawling geometry found in level / landscape data.

  Multiple world objects can (indeed should) be created from a single mesh object - see the Entity class for more info. The mesh object will have it's own default material properties, but potentially each world instance may wish to customise the materials from the original. When the object is instantiated into a scene node, the mesh material properties will be taken by default but may be changed. These properties are actually held at the SubMesh level since a single mesh may have parts with different materials.

  As described above, because the mesh may have sections of differing material properties, a mesh is inherently a compound construct, consisting of one or more SubMesh objects. However, it strongly 'owns' it's SubMeshes such that they are loaded / unloaded at the same time. This is contrary to the approach taken to hierarchically related (but loosely owned) scene nodes, where data is loaded / unloaded separately. Note also that mesh sub-sections (when used in an instantiated object) share the same scene node as the parent.

## Constructor & Destructor Documentation

## ◆ Mesh()

Ogre::Mesh::Mesh | ( | ResourceManager * | creator,
|  | const String & | name,
|  | ResourceHandle | handle,
|  | const String & | group,
|  | VaoManager * | vaoManager,
|  | bool | isManual = `false`,
|  | ManualResourceLoader * | loader = `0`
| ) |  |

Default constructor - used by MeshManager.

Warning
  Do not call this method directly.

## ◆ ~Mesh()

Ogre::Mesh::~Mesh | ( |  | ) |

## Member Function Documentation

## ◆ _dirtyState()

virtual void Ogre::Resource::_dirtyState | ( |  | ) |
| virtualinherited

Manually mark the state of this resource as having been changed.

Remarks
  You only need to call this from outside if you explicitly want derived objects to think this object has changed.

See also
  getStateCount.

## ◆ _fireLoadingComplete()

virtual void Ogre::Resource::_fireLoadingComplete | ( | bool | wasBackgroundLoaded | ) |
| virtualinherited

Firing of loading complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

  wasBackgroundLoaded | Whether this was a background loaded event

## ◆ _firePreparingComplete()

virtual void Ogre::Resource::_firePreparingComplete | ( | bool | wasBackgroundLoaded | ) |
| virtualinherited

Firing of preparing complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

  wasBackgroundLoaded | Whether this was a background loaded event

## ◆ _fireUnloadingComplete()

virtual void Ogre::Resource::_fireUnloadingComplete | ( | void |  | ) |
| virtualinherited

Firing of unloading complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

## ◆ _getLodValueArray()

const LodValueArray* Ogre::Mesh::_getLodValueArray | ( | void |  | ) | const
| inline

## ◆ _getVaoManager()

VaoManager* Ogre::Mesh::_getVaoManager | ( |  | ) | const
| inline

will return the vao manager that this mesh will use for creating and destroying array objects

## ◆ _notifyOrigin()

virtual void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) |
| inlinevirtualinherited

Notify this resource of it's origin.

## ◆ _notifySkeleton()

void Ogre::Mesh::_notifySkeleton | ( | v1::SkeletonPtr & | pSkel | ) |

Internal notification, used to tell the Mesh which Skeleton to use without loading it.

Remarks
  This is only here for unusual situation where you want to manually set up a Skeleton. Best to let OGRE deal with this, don't call it yourself unless you really know what you're doing.

## ◆ _setBoundingSphereRadius()

void Ogre::Mesh::_setBoundingSphereRadius | ( | Real | radius | ) |

Manually set the bounding radius.

Remarks
  Calling this method is required when building manual meshes now, because OGRE can no longer update the bounds for you, because it cannot necessarily read vertex data back from the vertex buffers which this mesh uses (they very well might be write-only, and even if they are not, reading data from a hardware buffer is a bottleneck).

## ◆ _setBounds()

void Ogre::Mesh::_setBounds | ( | const Aabb & | bounds,
|  | bool | pad = `true`
| ) |  |

Manually set the bounding box for this Mesh.

Remarks
  Calling this method is required when building manual meshes now, because OGRE can no longer update the bounds for you, because it cannot necessarily read vertex data back from the vertex buffers which this mesh uses (they very well might be write-only, and even if they are not, reading data from a hardware buffer is a bottleneck).

Parameters

  pad | If true, a certain padding will be added to the bounding box to separate it from the mesh

## ◆ _setLodInfo()

void Ogre::Mesh::_setLodInfo | ( | unsigned short | numLevels | ) |

Internal methods for loading LOD, do not use.

Referenced by Ogre::Lod0Stripifier::StripLod0Vertices().

## ◆ _setVaoManager()

void Ogre::Mesh::_setVaoManager | ( | VaoManager * | vaoManager | ) |
| inline

will manually set the vao manager the mesh will use when it loads.

setting this when the mesh is already loaded will cause a crash on unload, use with caution!

## ◆ _updateBoundsFromVertexBuffers()

void Ogre::Mesh::_updateBoundsFromVertexBuffers | ( | bool | pad = `false` | ) |

Automatically update the bounding radius and bounding box for this Mesh.

Remarks
  Calling this method is required when building manual meshes. However it is recommended to use _setBounds and _setBoundingSphereRadius instead, because the vertex buffer may not have a shadow copy in the memory. Reading back the buffer from video memory is very slow!

Parameters

  pad | If true, a certain padding will be added to the bounding box to separate it from the mesh

## ◆ addBoneAssignment()

void Ogre::Mesh::addBoneAssignment | ( | const VertexBoneAssignment & | vertBoneAssign | ) |

Assigns a vertex to a bone with a given weight, for skeletal animation.

Remarks
  This method is only valid after calling setSkeletonName. Since this is a one-off process there exists only 'addBoneAssignment' and 'clearBoneAssignments' methods, no 'editBoneAssignment'. You should not need to modify bone assignments during rendering (only the positions of bones) and OGRE reserves the right to do some internal data reformatting of this information, depending on render system requirements.

  This method is for assigning weights to the shared geometry of the Mesh. To assign weights to the per-SubMesh geometry, see the equivalent methods on SubMesh.

## ◆ addListener()

virtual void Ogre::Resource::addListener | ( | Listener * | lis | ) |
| virtualinherited

Register a listener on this resource.

See also
  Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ arrangeEfficient()

void Ogre::Mesh::arrangeEfficient | ( | bool | halfPos,
|  | bool | halfTexCoords,
|  | bool | qTangents
| ) |  |

Converts this SubMesh to an efficient arrangement.

@See Mesh::importV1 for an explanation on the parameters.

See also
  dearrangeEfficientToInefficient to perform the opposite operation.

## ◆ changeGroupOwnership()

virtual void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) |
| virtualinherited

Change the resource group ownership of a Resource.

Remarks
  This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters

  newGroup | Name of the new group

## ◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) |
| staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

## ◆ clearBoneAssignments()

void Ogre::Mesh::clearBoneAssignments | ( | void |  | ) |

Removes all bone assignments for this mesh.

Remarks
  This method is for modifying weights to the shared geometry of the Mesh. To assign weights to the per-SubMesh geometry, see the equivalent methods on SubMesh.

## ◆ clone()

MeshPtr Ogre::Mesh::clone | ( | const String & | newName,
|  | const String & | newGroup = `BLANKSTRING`,
|  | int | vertexBufferType = `-1`,
|  | int | indexBufferType = `-1`
| ) |  |

Makes a copy of this mesh object and gives it a new name.

Remarks
  This is useful if you want to tweak an existing mesh without affecting the original one. The newly cloned mesh is registered with the MeshManager under the new name.

Parameters

  newName | The name to give the clone.
  newGroup | Optional name of the new group to assign the clone to; if you leave this blank, the clone will be assigned to the same group as this Mesh.
  vertexBufferType | See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.
  indexBufferType | See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.

## ◆ copy()

void Ogre::Mesh::copy | ( | const MeshPtr & | destination,
|  | int | vertexBufferType = `-1`,
|  | int | indexBufferType = `-1`
| ) |  |

Will copy this mesh into the destination mesh.

Remarks
  similar to clone however will copy into a mesh you define rather than creating one for you.

Parameters

  destination | The mesh that will be the destination for the copy of *this
  vertexBufferType | See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.
  indexBufferType | See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.

## ◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const
| inlinevirtualinherited

Method for copying this object's parameters to another object.

Remarks
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters

  dest | Pointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

## ◆ createSubMesh()

SubMesh* Ogre::Mesh::createSubMesh | ( | size_t | index = `~0u` | ) |

Creates a new SubMesh.

Remarks
  Method for manually creating geometry for the mesh. Note - use with extreme caution - you must be sure that you have set up the geometry properly.

Parameters

  index | Optional param that will insert the submesh at the specified index. This should be less than getNumSubMeshes(), otherwise it indicates the new submesh will simply be appended to the submesh list.

## ◆ dearrangeToInefficient()

void Ogre::Mesh::dearrangeToInefficient | ( | void |  | ) |

Reverts the effects from arrangeEfficient by converting all 16-bit half float back to 32-bit float; and QTangents to Normal, Tangent + Reflection representation, which are more compatible for doing certain operations vertex operations in the CPU.

## ◆ destroySubMesh()

void Ogre::Mesh::destroySubMesh | ( | unsigned short | index | ) |

Destroy a SubMesh with the given index.

Note
  This will invalidate the contents of any existing Entity, or any other object that is referring to the SubMesh list. Entity will detect this and reinitialise, but it is still a disruptive action.

## ◆ escalateLoading()

virtual void Ogre::Resource::escalateLoading | ( |  | ) |
| virtualinherited

Escalates the loading of a background loaded resource.

Remarks
  If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ getAabb()

References Ogre::AtomicScalar< T >::get().

## ◆ getLodIndex()

uint16 Ogre::Mesh::getLodIndex | ( | Real | value | ) | const

Retrieves the level of detail index for the given LOD value.

Note
  The value passed in is the 'transformed' value. If you are dealing with an original source value (e.g. distance), use LodStrategy::transformUserValue to turn this into a lookup value.

## ◆ getStateCount()

virtual size_t Ogre::Resource::getStateCount | ( |  | ) | const
| inlinevirtualinherited

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

## ◆ getSubMesh()

SubMesh* Ogre::Mesh::getSubMesh | ( | unsigned short | index | ) | const

Gets a pointer to the submesh indicated by the index.

Referenced by Ogre::Lod0Stripifier::StripLod0Vertices().

## ◆ getSubMeshes()

const SubMeshVec& Ogre::Mesh::getSubMeshes | ( | void |  | ) | const
| inline

Gets an iterator over the available submeshes.

## ◆ getSubMeshNameMap()

const SubMeshNameMap& Ogre::Mesh::getSubMeshNameMap | ( | void |  | ) | const
| inline

Gets a reference to the optional name assignments of the SubMeshes.

## ◆ getVertexBufferDefaultType()

BufferType Ogre::Mesh::getVertexBufferDefaultType | ( | void |  | ) | const
| inline

Gets the usage setting for this meshes vertex buffers.

## ◆ hasIndependentShadowMappingVaos()

bool Ogre::Mesh::hasIndependentShadowMappingVaos | ( | void |  | ) | const

Returns true if the shadow mapping buffers do not just reference the real buffers, but are rather their own separate set of optimized geometry.

## ◆ hasSkeleton()

bool Ogre::Mesh::hasSkeleton | ( | void |  | ) | const
| inline

Returns true if this Mesh has a linked Skeleton.

## ◆ hasValidShadowMappingVaos()

bool Ogre::Mesh::hasValidShadowMappingVaos | ( | void |  | ) | const

Returns true if the mesh is ready for rendering with valid shadow mapping Vaos Otherwise prepareForShadowMapping must be called on this mesh.

## ◆ importV1()

void Ogre::Mesh::importV1 | ( | v1::Mesh * | mesh,
|  | bool | halfPos,
|  | bool | halfTexCoords,
|  | bool | qTangents,
|  | bool | halfPose = `true`
| ) |  |

Imports a v1 mesh to this mesh, with optional optimization conversions.

This mesh must be in unloaded state.

Remarks
  The vertex stream will be converted to a single interleaved buffer; i.e. if the original mesh had 3 vertex buffers: [1] = POSITION, POSITION, POSITION, POSITION, ... [2] = NORMALS, NORMALS, NORMALS, NORMALS, ... [3] = UV, UV, UV, UV, ... then the v2 mesh will have only 1 vertex buffer: [1] = POSITION NORMALS UV, POS NORM UV, POS NORM UV, POS NORM UV, ...

Parameters

  mesh | The source v1 mesh to convert from. You can unload or delete this pointer afterwards.
  halfPos | True if you want to convert the position data to VET_HALF4 format. Recommended on desktop to reduce memory and bandwidth requirements. Rarely the extra precision is needed. Unfortuntately on mobile, not all ES2 devices support VET_HALF4.
  halfTexCoords | True if you want to convert the position data to VET_HALF2 or VET_HALF4 format. Same recommendations as halfPos.
  qTangents | True if you want to generate tangent and reflection information (modifying the original v1 mesh) and convert this data to a QTangent, requiring VET_SHORT4_SNORM (8 bytes vs 28 bytes to store normals, tangents and reflection). Needs much less space, trading for more ALU ops in the vertex shader for decoding the QTangent. Highly recommended on both desktop and mobile if you need tangents (i.e. normal mapping).
  halfPose | True if you want the pose buffer to have pixel format PF_FLOAT16_RGBA which uses significantly less memory. Otherwise it is created with pixel format PF_FLOAT32_RGBA. Rarely the extra precision is needed.

## ◆ isBackgroundLoaded()

virtual bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const
| inlinevirtualinherited

Returns whether this Resource has been earmarked for background loading.

Remarks
  This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

| inline

Gets whether or not this meshes index buffers are shadowed.

## ◆ isLoaded()

virtual bool Ogre::Resource::isLoaded | ( | void |  | ) | const
| inlinevirtualinherited

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::get().

## ◆ isLoading()

| inlinevirtualinherited

Is this resource manually loaded?

## ◆ isPrepared()

virtual bool Ogre::Resource::isPrepared | ( | void |  | ) | const
| inlinevirtualinherited

Returns true if the Resource has been prepared, false otherwise.

References Ogre::AtomicScalar< T >::get().

## ◆ isReloadable()

virtual bool Ogre::Resource::isReloadable | ( | void |  | ) | const
| inlinevirtualinherited

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ isVertexBufferShadowed()

bool Ogre::Mesh::isVertexBufferShadowed | ( | void |  | ) | const
| inline

Gets whether or not this meshes vertex buffers are shadowed.

## ◆ load()

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) |
| virtualinherited

Loads the resource, if it is not already.

Remarks
  If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters

  backgroundThread | Indicates whether the caller of this method is the background resource loading thread.

## ◆ prepare()

virtual void Ogre::Resource::prepare | ( | bool | backgroundThread = `false` | ) |
| virtualinherited

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters

  backgroundThread | Whether this is occurring in a background thread

## ◆ prepareForShadowMapping()

void Ogre::Mesh::prepareForShadowMapping | ( | bool | forceSameBuffers | ) |

## ◆ reload()

virtual void Ogre::Resource::reload | ( | LoadingFlags | flags = `LF_DEFAULT` | ) |
| virtualinherited

Reloads the resource, if it is already loaded.

Remarks
  Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram, and Ogre::v1::Mesh.

## ◆ removeListener()

virtual void Ogre::Resource::removeListener | ( | Listener * | lis | ) |
| virtualinherited

Remove a listener on this resource.

See also
  Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ removeLodLevels()

void Ogre::Mesh::removeLodLevels | ( | void |  | ) |

Internal methods for loading LOD, do not use.

Removes all LOD data from this Mesh.

## ◆ setBackgroundLoaded()

virtual void Ogre::Resource::setBackgroundLoaded | ( | bool | bl | ) |
| inlinevirtualinherited

Tells the resource whether it is background loaded or not.

Remarks

See also
  Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ setIndexBufferPolicy()

void Ogre::Mesh::setIndexBufferPolicy | ( | BufferType | bufferType,
|  | bool | shadowBuffer = `false`
| ) |  |

Sets the policy for the index buffers to be used when loading this Mesh.

See also
  setVertexBufferPolicy

## ◆ setLodStrategyName()

| inline

## ◆ setManuallyLoaded()

virtual void Ogre::Resource::setManuallyLoaded | ( | bool | isManual | ) |
| inlinevirtualinherited

Set "Is this resource manually loaded?".

## ◆ setParameter()

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value
| ) |  |
| virtualinherited

Generic parameter setting method.

Remarks
  Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

  name | The name of the parameter to set
  value | String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns
  true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

## ◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) |
| virtualinherited

Generic multiple parameter setting method.

Remarks
  Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

  paramList | Name/value pair list

## ◆ setSkeletonName()

void Ogre::Mesh::setSkeletonName | ( | const String & | skelName | ) |

Calculates.

Remarks
  Calling this method is required when building manual meshes. However it is recommended to use _setBounds and _setBoundingSphereRadius instead, because the vertex buffer may not have a shadow copy in the memory. Reading back the buffer from video memory is very slow! Sets the name of the skeleton this Mesh uses for animation.
  Meshes can optionally be assigned a skeleton which can be used to animate the mesh through bone assignments. The default is for the Mesh to use no skeleton. Calling this method with a valid skeleton filename will cause the skeleton to be loaded if it is not already (a single skeleton can be shared by many Mesh objects).

Parameters

  skelName | The name of the .skeleton file to use, or an empty string to use no skeleton

## ◆ setToLoaded()

virtual void Ogre::Resource::setToLoaded | ( | void |  | ) |
| inlinevirtualinherited

Change the Resource loading state to loaded.

References Ogre::AtomicScalar< T >::set().

## ◆ setVertexBufferPolicy()

void Ogre::Mesh::setVertexBufferPolicy | ( | BufferType | bufferType,
|  | bool | shadowBuffer = `false`
| ) |  |

Sets the policy for the vertex buffers to be used when loading this Mesh.

Remarks
  By default, when loading the Mesh, immutable buffers will be used where possible in order to improve rendering performance. However, such buffers cannot be manipulated on the fly by CPU code (although shader code can). If you wish to use the CPU to modify these buffers, you should call this method. Note, however, that it only takes effect after the Mesh has been reloaded. Note that you still have the option of manually repacing the buffers in this mesh with your own if you see fit too, in which case you don't need to call this method since it only affects buffers created by the mesh itself.

  You can define the approach to a Mesh by changing the default parameters to MeshManager::load if you wish; this means the Mesh is loaded with those options the first time instead of you having to reload the mesh after changing these options.

Parameters

  bufferType | The buffer type flags, which by default is BT_IMMUTABLE
  shadowBuffer | If set to `true`, the vertex buffers will be created with a system memory shadow buffer. You should set this if you want to be able to read from the buffer, because reading from a hardware buffer is a no-no.

## ◆ touch()

virtual void Ogre::Resource::touch | ( | void |  | ) |
| virtualinherited

'Touches' the resource to indicate it has been used.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram, and Ogre::Material.

Referenced by Ogre::Material::touch().

## ◆ unload()

virtual void Ogre::Resource::unload | ( | void |  | ) |
| virtualinherited

Unloads the resource; this is not permanent, the resource can be reloaded later if required.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ unnameSubMesh()

void Ogre::Mesh::unnameSubMesh | ( | const String & | name | ) |

Removes a name from a SubMesh.

## ◆ msOptimizeForShadowMapping

bool Ogre::Mesh::msOptimizeForShadowMapping
| static

When this bool is false, prepareForShadowMapping will use the same Vaos for both regular and shadow mapping rendering.

When it's true, it will calculate an optimized version to speed up shadow map rendering (uses a bit more GPU VRAM). Large meshes can take long to optimize thus it is recommended to perform this offline and save it into the mesh file. It's off by default.
