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.

Member Function Documentation

◆ createSubMesh() [1/2]

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.

◆ createSubMesh() [2/2]

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

Creates a new SubMesh and gives it a name.

◆ nameSubMesh()

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

Removes a name from a SubMesh.

◆ _getSubMeshIndex()

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

Remarks: Useful if you identify the SubMeshes by name (using nameSubMesh) but wish to have faster repeat access.

◆ getNumSubMeshes()

size_t Ogre::Mesh::getNumSubMeshes ( void ) const

inline

Gets the number of sub meshes which comprise this mesh.

Deprecated:: use getSubMeshes() instead

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

◆ getSubMesh() [1/2]

SubMesh* Ogre::Mesh::getSubMesh ( size_t index ) const

inline

Gets a pointer to the submesh indicated by the index.

Deprecated:: use getSubMeshes() instead

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

◆ getSubMesh() [2/2]

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

Gets a SubMesh by name.

◆ destroySubMesh() [1/2]

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.

◆ destroySubMesh() [2/2]

void Ogre::Mesh::destroySubMesh ( const String & name )

Destroy a SubMesh with the given name.

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.

◆ getSubMeshIterator()

SubMeshIterator Ogre::Mesh::getSubMeshIterator ( void )

inline

Gets an iterator over the available submeshes.

Deprecated:: use getSubMeshes() instead

◆ getSubMeshes()

const SubMeshList& Ogre::Mesh::getSubMeshes ( ) const

inline

Gets the available submeshes.

◆ clone()

MeshPtr Ogre::Mesh::clone	(	const String &	newName,
		const String &	newGroup = `BLANKSTRING`
	)

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.

◆ reload()

void Ogre::Mesh::reload ( LoadingFlags flags = LF_DEFAULT )

overridevirtual

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 from Ogre::Resource.

◆ getBounds()

const AxisAlignedBox& Ogre::Mesh::getBounds ( void ) const

Get the axis-aligned bounding box for this mesh.

◆ getBoundingSphereRadius()

Real Ogre::Mesh::getBoundingSphereRadius ( void ) const

Gets the radius of the bounding sphere surrounding this mesh.

◆ getBoneBoundingRadius()

Real Ogre::Mesh::getBoneBoundingRadius ( ) const

Gets the radius used to inflate the bounding box around the bones.

◆ _setBounds()

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

bounds	The axis-aligned bounding box for this mesh
pad	If true, a certain padding will be added to the bounding box to separate it from the mesh

◆ _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).

◆ _setBoneBoundingRadius()

void Ogre::Mesh::_setBoneBoundingRadius ( Real radius )

Manually set the bone bounding radius.

Remarks: This value is normally computed automatically, however it can be overridden with this method.

◆ _computeBoneBoundingRadius()

void Ogre::Mesh::_computeBoneBoundingRadius ( )

Compute the bone bounding radius by looking at the vertices, vertex-bone-assignments, and skeleton bind pose.

Remarks: This is automatically called by Entity if necessary. Only does something if the boneBoundingRadius is zero to begin with. Only works if vertex data is readable (i.e. not WRITE_ONLY).

◆ _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

◆ _calcBoundsFromVertexBuffer()

void Ogre::Mesh::_calcBoundsFromVertexBuffer	(	VertexData *	vertexData,
		AxisAlignedBox &	outAABB,
		Real &	outRadius,
		bool	updateOnly = `false`
	)

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!

◆ setSkeletonName()

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

◆ hasSkeleton()

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

inline

Returns true if this Mesh has a linked Skeleton.

◆ hasVertexAnimation()

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

Returns whether or not this mesh has some kind of vertex animation.

◆ getSkeleton()

const SkeletonPtr& Ogre::Mesh::getSkeleton ( void ) const

inline

Gets a pointer to any linked Skeleton.

Returns: Weak reference to the skeleton - copy this if you want to hold a strong pointer.

◆ getSkeletonName()

const String& Ogre::Mesh::getSkeletonName ( void ) const

Gets the name of any linked Skeleton.

◆ _initAnimationState()

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.

◆ _refreshAnimationState()

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

Refresh an animation set suitable for use with this mesh.

Remarks: Only recommended for use inside the engine, not by applications.

◆ 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.

◆ 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.

◆ _notifySkeleton()

void Ogre::Mesh::_notifySkeleton ( const SkeletonPtr & pSkel )

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

inline

Sets the manager for the vertex and index buffers to be used when loading this Mesh.

Parameters

bufferManager If set to DefaultHardwareBufferManager, the buffers will be created in system memory only, without hardware counterparts. Such mesh could not be rendered, but LODs could be generated for such mesh, it could be cloned, transformed and serialized.

◆ getHardwareBufferManager()

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

◆ setVertexBufferPolicy()

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

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

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: This only takes effect after the Mesh has been reloaded. Also, you still have the option of manually replacing 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 flag, which by default is HBU_GPU_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

◆ setIndexBufferPolicy()

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

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

By default, when loading the Mesh, static, write-only vertex and index buffers will be used where possible in order to improve rendering performance.

◆ _rationaliseBoneAssignments()

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]

◆ _compileBoneAssignments()

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.

◆ _updateCompiledBoneAssignments()

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.

◆ mergeAdjacentTexcoords()

void Ogre::Mesh::mergeAdjacentTexcoords	(	unsigned short	finalTexCoordSet,
		unsigned short	texCoordSetToDestroy
	)

This method collapses two texcoords into one for all submeshes where this is possible.

Remarks: Often a submesh can have two tex. coords. (i.e. TEXCOORD0 & TEXCOORD1), being both composed of two floats. There are many practical reasons why it would be more convenient to merge both of them into one TEXCOORD0 of 4 floats. This function does exactly that The finalTexCoordSet must have enough space for the merge, or else the submesh will be skipped. (i.e. you can't merge a tex. coord with 3 floats with one having 2 floats)

finalTexCoordSet & texCoordSetToDestroy must be in the same buffer source, and must be adjacent.

Parameters

finalTexCoordSet	The tex. coord index to merge to. Should have enough space to actually work.
texCoordSetToDestroy	The texture coordinate index that will disappear on successful merges.

◆ buildTangentVectors()

void Ogre::Mesh::buildTangentVectors	(	VertexElementSemantic	targetSemantic = `VES_TANGENT`,
		unsigned short	sourceTexCoordSet = `0`,
		unsigned short	index = `0`,
		bool	splitMirrored = `false`,
		bool	splitRotated = `false`,
		bool	storeParityInW = `false`
	)

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

targetSemantic	The semantic to store the tangents in. Defaults to the explicit tangent binding, but note that this is only usable on more modern hardware (Shader Model 2), so if you need portability with older cards you should change this to a texture coordinate binding instead.
sourceTexCoordSet	The texture coordinate index which should be used as the source of 2D texture coordinates, with which to calculate the tangents.
index	The element index, ie the texture coordinate set which should be used to store the 3D coordinates representing a tangent vector per vertex, if targetSemantic is VES_TEXTURE_COORDINATES. If this already exists, it will be overwritten.
splitMirrored	Sets whether or not to split vertices when a mirrored tangent space transition is detected (matrix parity differs).

See also: TangentSpaceCalc::setSplitMirrored

Parameters

splitRotated Sets whether or not to split vertices when a rotated tangent space is detected.

See also: TangentSpaceCalc::setSplitRotated

Parameters

storeParityInW If true, store tangents as a 4-vector and include parity in w.

◆ suggestTangentVectorBuildParams()

bool Ogre::Mesh::suggestTangentVectorBuildParams	(	VertexElementSemantic	targetSemantic,
		unsigned short &	outSourceCoordSet,
		unsigned short &	outIndex
	)

Ask the mesh to suggest parameters to a future buildTangentVectors call, should you wish to use texture coordinates to store the tangents.

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 already 3D coordinates in the mesh, and therefore tangents may have been prepared already.

Parameters

targetSemantic	The semantic you intend to use to store the tangents if they are not already present; most likely options are VES_TEXTURE_COORDINATES or VES_TANGENT; you should use texture coordinates if you want compatibility with older, pre-SM2 graphics cards, and the tangent binding otherwise.
outSourceCoordSet	Reference to a source texture coordinate set which will be populated.
outIndex	Reference to a destination element index (e.g. texture coord set) which will be populated

◆ buildEdgeList()

void Ogre::Mesh::buildEdgeList ( void )

◆ freeEdgeList()

void Ogre::Mesh::freeEdgeList ( void )

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

◆ prepareForShadowVolume()

void Ogre::Mesh::prepareForShadowVolume ( void )

Modifies the vertex data to be suitable for use for rendering shadow geometry as in [10].

Preparing vertex data to generate a shadow volume involves firstly ensuring that the vertex buffer containing the positions is a standalone vertex buffer, with no other components in it. This method will therefore break apart any existing vertex buffers 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. The vertex count used to render 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.

It's important to appreciate that this method can fundamentally change the structure of your vertex buffers, although in reality they will be new buffers. As it happens, if other objects are using the original buffers then they will be unaffected because the reference counting will keep them intact. However, if you have made any assumptions about the structure of the vertex data in the buffers of this object, you may have to rethink them.

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.

		const Affine3 *	boneMatrices,
		const IndexMap &	indexMap
	)

static

	)

static

Performs a software indexed vertex blend, of the kind used for skeletal animation although it can be used for other purposes.

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

		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.
normalsMap	Potentially sparse map of vertex index -> normal.
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.

Member Data Documentation

◆ sharedVertexData

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.

: The use of shared or non-shared buffers is determined when model data is converted to the OGRE .mesh format.

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

◆ sharedBlendIndexToBoneIndexMap

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.
