Member Function Documentation

void Ogre::Mesh::_compileBoneAssignments (  void   )

Internal method, be called once to compile bone assignments into geometry buffer. Remarks: The OGRE engine calls this method automatically. It compiles the information submitted as bone assignments into a format usable in realtime. It also eliminates excessive bone assignments (max is OGRE_MAX_BLEND_WEIGHTS) and re-normalises the remaining assignments.

void Ogre::Mesh::_determineAnimationTypes (  void   )  const

Internal method which, if animation types have not been determined, scans any vertex animations and determines the type for each set of vertex data (cannot have 2 different types).

virtual Animation* Ogre::Mesh::_getAnimationImpl (  const String &  name  )  const [virtual]

Internal access to the named vertex Animation object - returns null if it does not exist. Parameters: name  The name of the animation

bool Ogre::Mesh::_getAnimationTypesDirty (  void   )  const

Are the derived animation types out of date? Definition at line 763 of file OgreMesh.h.

ushort Ogre::Mesh::_getSubMeshIndex (  const String &  name  )  const

Gets the index of a submesh with a given name. Remarks: Useful if you identify the SubMeshes by name (using nameSubMesh) but wish to have faster repeat access.

void Ogre::Mesh::_initAnimationState (  AnimationStateSet *  animSet  )

Initialise an animation set suitable for use with this mesh. Remarks: Only recommended for use inside the engine, not by applications.

void Ogre::Resource::_notifyOrigin (  const String &  origin  )  [inherited]

Notify this resource of it's origin. Definition at line 223 of file OgreResource.h. References Ogre::String.

void Ogre::Mesh::_notifySkeleton (  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.

unsigned short Ogre::Mesh::_rationaliseBoneAssignments (  size_t  vertexCount, VertexBoneAssignmentList &  assignments )

Rationalises the passed in bone assignment list. Remarks: OGRE supports up to 4 bone assignments per vertex. The reason for this limit is that this is the maximum number of assignments that can be passed into a hardware-assisted blending algorithm. This method identifies where there are more than 4 bone assignments for a given vertex, and eliminates the bone assignments with the lowest weights to reduce to this limit. The remaining weights are then re-balanced to ensure that they sum to 1.0. Parameters: vertexCount  The number of vertices. assignments  The bone assignment list to rationalise. This list will be modified and entries will be removed where the limits are exceeded. Returns: The maximum number of bone assignments per vertex found, clamped to [1-4]

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).

void Ogre::Mesh::_setBounds (  const AxisAlignedBox &  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

void Ogre::Mesh::_setLodInfo (  unsigned short  numLevels, bool  isManual )

Internal methods for loading LOD, do not use.

void Ogre::Mesh::_setLodUsage (  unsigned short  level, MeshLodUsage &  usage )

Internal methods for loading LOD, do not use.

void Ogre::Mesh::_setSubMeshLodFaceList (  unsigned short  subIdx, unsigned short  level, IndexData *  facedata )

Internal methods for loading LOD, do not use.

void Ogre::Mesh::_updateCompiledBoneAssignments (  void   )

Internal method, be called once to update the compiled bone assignments. Remarks: The OGRE engine calls this method automatically. It updates the compiled bone assignments if requested.

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.

void Ogre::Mesh::buildEdgeList (  void   )

Builds an edge list for this mesh, which can be used for generating a shadow volume among other things.

void Ogre::Mesh::buildIndexMap (  const VertexBoneAssignmentList &  boneAssignments, IndexMap &  boneIndexToBlendIndexMap, IndexMap &  blendIndexToBoneIndexMap )  [protected]

Build the index map between bone index and blend index.

void Ogre::Mesh::buildTangentVectors (  unsigned short  sourceTexCoordSet = 0, unsigned short  destTexCoordSet = 1 )

This method builds a set of tangent vectors for a given mesh into a 3D texture coordinate buffer. Remarks: Tangent vectors are vectors representing the local 'X' axis for a given vertex based on the orientation of the 2D texture on the geometry. They are built from a combination of existing normals, and from the 2D texture coordinates already baked into the model. They can be used for a number of things, but most of all they are useful for vertex and fragment programs, when you wish to arrive at a common space for doing per-pixel calculations. The prerequisites for calling this method include that the vertex data used by every SubMesh has both vertex normals and 2D texture coordinates. Parameters: sourceTexCoordSet  The texture coordinate index which should be used as the source of 2D texture coordinates, with which to calculate the tangents. destTexCoordSet  The texture coordinate set which should be used to store the 3D coordinates representing a tangent vector per vertex. If this already exists, it will be overwritten.

size_t Ogre::Mesh::calculateSize (  void   )  const [protected, virtual]

Implements Ogre::Resource.

void Ogre::Resource::changeGroupOwnership (  const String &  newGroup  )  [inherited]

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

void Ogre::StringInterface::cleanupDictionary (   )  [static, inherited]

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.

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.

MeshPtr Ogre::Mesh::clone (  const String &  newName, const String &  newGroup = StringUtil::BLANK )

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.

void Ogre::Mesh::compileBoneAssignments (  const VertexBoneAssignmentList &  boneAssignments, unsigned short  numBlendWeightsPerVertex, IndexMap &  blendIndexToBoneIndexMap, VertexData *  targetVertexData )  [protected]

Compile bone assignments into blend index and weight buffers.

virtual void Ogre::StringInterface::copyParametersTo (  StringInterface *  dest  )  const [virtual, inherited]

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. Definition at line 296 of file OgreStringInterface.h. References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

virtual Animation* Ogre::Mesh::createAnimation (  const String &  name, Real  length )  [virtual]

Creates a new Animation object for vertex animating this mesh. Parameters: name  The name of this animation length  The length of the animation in seconds

void Ogre::Mesh::createManualLodLevel (  Real  fromDepth, const String &  meshName )

Adds a new manual level-of-detail entry to this Mesh. Remarks: As an alternative to generating lower level of detail versions of a mesh, you can use your own manually modelled meshes as lower level versions. This lets you have complete control over the LOD, and in addition lets you scale down other aspects of the model which cannot be done using the generated method; for example, you could use less detailed materials and / or use less bones in the skeleton if this is an animated mesh. Therefore for complex models you are likely to be better off modelling your LODs yourself and using this method, whilst for models with fairly simple materials and no animation you can just use the generateLodLevels method. Parameters: fromDepth  The z value from which this Lod will apply. meshName  The name of the mesh which will be the lower level detail version.

bool Ogre::StringInterface::createParamDictionary (  const String &  className  )  [protected, inherited]

Internal method for creating a parameter dictionary for the class, if it does not already exist. Remarks: This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance). Parameters: className  the name of the class using the dictionary Returns: true if a new dictionary was created, false if it was already there Definition at line 172 of file OgreStringInterface.h. References Ogre::String.

Pose* Ogre::Mesh::createPose (  ushort  target, const String &  name = StringUtil::BLANK )

Create a new Pose for this mesh or one of its submeshes. Parameters: target  The target geometry index; 0 is the shared Mesh geometry, 1+ is the dedicated SubMesh geometry belonging to submesh index + 1. name  Name to give the pose, which is optional Returns: A new Pose ready for population

SubMesh* Ogre::Mesh::createSubMesh (  const String &  name  )

Creates a new SubMesh and gives it a name.

SubMesh* Ogre::Mesh::createSubMesh (  void   )

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.

void Ogre::Mesh::freeEdgeList (  void   )

Destroys and frees the edge lists this mesh has built.

void Ogre::Mesh::generateLodLevels (  const LodDistanceList &  lodDistances, ProgressiveMesh::VertexReductionQuota  reductionMethod, Real  reductionValue )

Automatically generates lower level of detail versions of this mesh for use when a simpler version of the model is acceptable for rendering. Remarks: There are 2 ways that you can create level-of-detail (LOD) versions of a mesh; the first is to call this method, which does fairly extensive calculations to work out how to simplify the mesh whilst having the minimum affect on the model. The alternative is to actually create simpler versions of the mesh yourself in a modelling tool, and having exported them, tell the 'master' mesh to use these alternative meshes for lower detail versions; this is done by calling the createManualLodLevel method. As well as creating the lower detail versions of the mesh, this method will also associate them with depth values. As soon as an object is at least as far away from the camera as the depth value associated with it's LOD, it will drop to that level of detail. I recommend calling this method before mesh export, not at runtime. Parameters: lodDistances  A list of depth values indicating the distances at which new lods should be generated. reductionMethod  The way to determine the number of vertices collapsed per LOD reductionValue  Meaning depends on reductionMethod, typically either the proportion of remaining vertices to collapse or a fixed number of vertices.

virtual Animation* Ogre::Mesh::getAnimation (  unsigned short  index  )  const [virtual]

Gets a single morph animation by index.

virtual Animation* Ogre::Mesh::getAnimation (  const String &  name  )  const [virtual]

void Ogre::Mesh::loadImpl (  void   )  [protected, virtual]

Implements Ogre::Resource. Reimplemented in Ogre::PatchMesh.

void Ogre::Mesh::nameSubMesh (  const String &  name, ushort  index )

Gives a name to a SubMesh.

void Ogre::Mesh::organiseTangentsBuffer (  VertexData *  vertexData, unsigned short  destCoordSet )  [protected]

Internal method for making the space for a 3D texture coord buffer to hold tangents.

void Ogre::Mesh::prepareForShadowVolume (  void   )

This method prepares the mesh for generating a renderable shadow volume. Remarks: Preparing a mesh to generate a shadow volume involves firstly ensuring that the vertex buffer containing the positions for the mesh is a standalone vertex buffer, with no other components in it. This method will therefore break apart any existing vertex buffers this mesh holds if position is sharing a vertex buffer. Secondly, it will double the size of this vertex buffer so that there are 2 copies of the position data for the mesh. The first half is used for the original, and the second half is used for the 'extruded' version of the mesh. The vertex count of the main VertexData used to render the mesh will remain the same though, so as not to add any overhead to regular rendering of the object. Both copies of the position are required in one buffer because shadow volumes stretch from the original mesh to the extruded version. Because shadow volumes are rendered in turn, no additional index buffer space is allocated by this method, a shared index buffer allocated by the shadow rendering algorithm is used for addressing this extended vertex buffer.

virtual void Ogre::Resource::reload (  void   )  [virtual, inherited]

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.

Removes all morph Animations from this mesh.

void Ogre::Mesh::removeAllPoses (  void   )

Destroy all poses.

virtual void Ogre::Mesh::removeAnimation (  const String &  name  )  [virtual]

Removes vertex Animation from this mesh.

void Ogre::Mesh::removeLodLevels (  void   )

void Ogre::Mesh::removePose (  ushort  index  )

Destroy a pose by index. Note: This will invalidate any animation tracks referring to this pose or those after it.

void Ogre::Mesh::setAutoBuildEdgeLists (  bool  autobuild  )

Sets whether or not this Mesh should automatically build edge lists when asked for them, or whether it should never build them if they are not already provided. Remarks: This allows you to create meshes which do not have edge lists calculated, because you never want to use them. This value defaults to 'true' for mesh formats which did not include edge data, and 'false' for newer formats, where edge lists are expected to have been generated in advance. Definition at line 695 of file OgreMesh.h.

void Ogre::Mesh::setIndexBufferPolicy (  HardwareBuffer::Usage  usage, bool  shadowBuffer = false )

Sets the policy for the index buffers to be used when loading this Mesh. Remarks: By default, when loading the Mesh, static, write-only vertex and index 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: usage  The usage flags, which by default are HardwareBuffer::HBU_STATIC_WRITE_ONLY shadowBuffer  If set to true, the index 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.

virtual bool Ogre::StringInterface::setParameter (  const String &  name, const String &  value )  [virtual, inherited]

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().

virtual void Ogre::StringInterface::setParameterList (  const NameValuePairList &  paramList  )  [virtual, inherited]

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

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

Sets the name of the skeleton this Mesh uses for animation. Remarks: 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

void Ogre::Mesh::setVertexBufferPolicy (  HardwareBuffer::Usage  usage, bool  shadowBuffer = false )

Sets the policy for the vertex buffers to be used when loading this Mesh. Remarks: By default, when loading the Mesh, static, write-only vertex and index 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: usage  The usage flags, which by default are HardwareBuffer::HBU_STATIC_WRITE_ONLY 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.

void Ogre::Mesh::softwareVertexBlend (  const VertexData *  sourceVertexData, const VertexData *  targetVertexData, const Matrix4 *  pMatrices, const unsigned short *  pIndexMap, bool  blendNormals )  [static]

Performs a software indexed vertex blend, of the kind used for skeletal animation although it can be used for other purposes. Remarks: This function is supplied to update vertex data with blends done in software, either because no hardware support is available, or that you need the results of the blend for some other CPU operations. Parameters: sourceVertexData  VertexData class containing positions, normals, blend indices and blend weights. targetVertexData  VertexData class containing target position and normal buffers which will be updated with the blended versions. Note that the layout of the source and target position / normal buffers must be identical, ie they must use the same buffer indexes pMatrices  Pointer to an array of matrices to be used to blend pIndexMap  Pointer to an array of indices to translate blend indices in the sourceVertexData to the index of pMatrices blendNormals  If true, normals are blended as well as positions

void Ogre::Mesh::softwareVertexMorph (  Real  t, const HardwareVertexBufferSharedPtr &  b1, const HardwareVertexBufferSharedPtr &  b2, VertexData *  targetVertexData )  [static]

Performs a software vertex morph, of the kind used for morph animation although it can be used for other purposes. Remarks: This function will linearly interpolate positions between two source buffers, into a third buffer. Parameters: t  Parametric distance between the start and end buffer positions b1  Vertex buffer containing VET_FLOAT3 entries for the start positions b2  Vertex buffer containing VET_FLOAT3 entries for the end positions targetVertexData  VertexData destination; assumed to have a separate position buffer already bound, and the number of vertices must agree with the number in start and end

void Ogre::Mesh::softwareVertexPoseBlend (  Real  weight, const std::map< size_t, Vector3 > &  vertexOffsetMap, VertexData *  targetVertexData )  [static]

Performs a software vertex pose blend, of the kind used for morph animation although it can be used for other purposes. Remarks: This function will apply a weighted offset to the positions in the incoming vertex data (therefore this is a read/write operation, and if you expect to call it more than once with the same data, then you would be best to suppress hardware uploads of the position buffer for the duration) Parameters: weight  Parametric weight to scale the offsets by vertexOffsetMap  Potentially sparse map of vertex index -> offset targetVertexData  VertexData destination; assumed to have a separate position buffer already bound, and the number of vertices must agree with the number in start and end

bool Ogre::Mesh::suggestTangentVectorBuildParams (  unsigned short &  outSourceCoordSet, unsigned short &  outDestCoordSet )

Ask the mesh to suggest parameters to a future buildTangentVectors call. Remarks: This helper method will suggest source and destination texture coordinate sets for a call to buildTangentVectors. It will detect when there are inappropriate conditions (such as multiple geometry sets which don't agree). Moreover, it will return 'true' if it detects that there are aleady 3D coordinates in the mesh, and therefore tangents may have been prepared already. Parameters: outSourceCoordSet  Reference to a source texture coordinate set which will be populated outDestCoordSet  Reference to a destination texture coordinate set which will be populated

virtual void Ogre::Resource::touch (  void   )  [virtual, inherited]

'Touches' the resource to indicate it has been used. Reimplemented in Ogre::Material.

virtual void Ogre::Resource::unload (  void   )  [virtual, inherited]

void Ogre::Mesh::unloadImpl (  void   )  [protected, virtual]

Implements Ogre::Resource.

void Ogre::Mesh::updateManualLodLevel (  ushort  index, const String &  meshName )

Changes the alternate mesh to use as a manual LOD at the given index. Remarks: Note that the index of a LOD may change if you insert other LODs. If in doubt, use getLodIndex(). Parameters: index  The index of the level to be changed meshName  The name of the mesh which will be the lower level detail version.

void Ogre::Mesh::updateMaterialForAllSubMeshes (  void   )

Iterates through all submeshes and requests them to apply their texture aliases to the material they use. Remarks: The submesh will only apply texture aliases to the material if matching texture alias names are found in the material. If a match is found, the submesh will automatically clone the original material and then apply its texture to the new material. This method is normally called by the protected method loadImpl when a mesh if first loaded.

IndexMap Ogre::Mesh::sharedBlendIndexToBoneIndexMap

Shared index map for translating blend index to bone index. Remarks: This index map can be shared among multiple submeshes. SubMeshes might not have their own IndexMap, they might share this one. We collect actually used bones of all bone assignments, and build the blend index in 'packed' form, then the range of the blend index in vertex data VES_BLEND_INDICES element is continuous, with no gaps. Thus, by minimising the world matrix array constants passing to GPU, we can support more bones for a mesh when hardware skinning is used. The hardware skinning support limit is applied to each set of vertex data in the mesh, in other words, the hardware skinning support limit is applied only to the actually used bones of each SubMeshes, not all bones across the entire Mesh. Because the blend index is different to the bone index, therefore, we use the index map to translate the blend index to bone index. The use of shared or non-shared index map is determined when model data is converted to the OGRE .mesh format. Definition at line 263 of file OgreMesh.h.

VertexData* Ogre::Mesh::sharedVertexData

Shared vertex data. Remarks: This vertex data can be shared among multiple submeshes. SubMeshes may not have their own VertexData, they may share this one.
