Member Function Documentation

addFace()

size_t agxUtil::RawMesh::addFace

(

const IndexVector &

vertices

)

Add a face to the object stored with the specified vertices.

The vertices is assumed to be stored clockwise from the 'up' side.

Parameters

vertices

the IDs of the vertices of the face

Returns

the ID of the added face

addVertex()

size_t agxUtil::RawMesh::addVertex

(

const agx::Vec3 &

position

)

Add a vertex to the object on the specified position.

Parameters

position

the position of the added vertex

Returns

the ID of the added vertex

getFaceArea()

agx::Real agxUtil::RawMesh::getFaceArea

(

size_t

face

)

const

Get the area of a face.

This is calculated by taking the mid point of all the vertices, and then calculating the area of each triangle defined by two neighbours and the mid point. Unfortunately, this only gives the correct answer if the polygon is convex.

Parameters

face	the ID of the face

Returns

the area of the face

getFacesFromVertex()

const IndexVector & agxUtil::RawMesh::getFacesFromVertex

(

size_t

vertex

)

const

Get the faces which contain a specified vertex.

Parameters

vertex

the ID of the vertex

Returns

a list of the IDs of all the faces

getFaceVertices()

const IndexVector & agxUtil::RawMesh::getFaceVertices

(

size_t

face

)

const

Get the index each vertex in the specified face.

They are ordered clockwise, with the last index being connected to the first.

getName()

const agx::String & agxUtil::RawMesh::getName

(

)

const

Get the name of the mesh.

Returns

the name which the mesh is initialized with

getNumFaces()

size_t agxUtil::RawMesh::getNumFaces

(

)

const

Get the number of faces stored in the mesh.

Returns

the number of faces stored in the object

getNumVertices()

size_t agxUtil::RawMesh::getNumVertices

(

)

const

Get the number of vertices stored in the mesh.

Observe, that depending on initialization, not all vertices need to be part of a face.

Returns

the number of vertices stored in the object

getTotalArea()

agx::Real agxUtil::RawMesh::getTotalArea

(

)

const

Get the area of all the triangles calculated as described for getFaceArea.

Returns

the total area of the mesh

getVertexArea()

agx::Real agxUtil::RawMesh::getVertexArea

(

size_t

vertex

)

const

Get the area represented by a single vertex.

This is calculated as an equal part of each face the vertex is part of.

getVertexPosition()

agx::Vec3 agxUtil::RawMesh::getVertexPosition

(

size_t

vertex

)

const

Get the position of a vertex.

Parameters

vertex

the ID of the vertex

Returns

the position of the vertex
