Detailed Description

template<typename TOutputMesh>
class itk::AutomaticTopologyMeshSource< TOutputMesh >

Convenience class for generating meshes.

This generates an N-dimensional mesh consisting of some combination of vertices, line segments, triangles, quadrilaterals, tetrahedra, and hexahedra. Identifiers for the cells are automatically added, and topological connectivity is automatically computed. When a cell is added, all of its boundary features are determined and added as well.

The main methods are of the form AddThing, where Thing can be Point, Vertex, Triangle, Quadrilateral, Tetrahedron, or Hexahedron. Each of these methods has several overloaded forms, permitting multiple ways to specify the object being added. When called, each of these methods first checks to see if the object has already been added. If it has not, then a new identifier is generated (the smallest one so far unused), the object is added with that identifier, and the ID is returned. If the object has already been added, then the ID it already has is returned and nothing else is done.

When a cell is added, all of its boundary elements are also added, and boundary assignments are set. A cell can be specified using IDs of points already added, or using Point objects that may or may not already be in the mesh. If a cell is specified using Point objects, then the points are added to the mesh if necessary.

The different ways of specifying a cell are

An IdentifierArrayType (= itk::Array<IdentifierType>) of point identifiers. These point identifiers are the ones returned by calls to AddPoint().
A parameter list of point identifiers (for instance, this->AddLine(0, 1), if 0 and 1 are point identifiers).
A parameter list of itk::Point objects (the function then generates the identifiers).
A parameter list of C-style arrays, with each such array giving the coordinates of one point. This form is useful for copying in geometry from foreign data structures.

For meshes generated using this filter, only one cell can be added for any given set of vertices. If a, b, c, and d are identifiers for four points in R^3, then (a, b, c, d) and (a, c, d, b) determine two different quadrilaterals (at least one of which is either degenerate or nonplanar). If you call

AddQuadrilateral(a, b, c, d);

AddQuadrilateral(a, c, d, b);

itk::AutomaticTopologyMeshSource::AddQuadrilateral

IdentifierType AddQuadrilateral(const IdentifierArrayType &pointIDs)

then only the first quadrilateral will actually be added.

To add the topological information to an already constructed mesh (for efficiency of traversal), use this class to generate a copy of the original mesh.

Example: The following code generates a mesh consisting of two triangles sharing an edge.

using MeshSourceType = itk::AutomaticTopologyMeshSource< MeshType >;
auto meshSource = MeshSourceType::New();
meshSource->AddTriangle(
  meshSource->AddPoint(0, 0, 0),
  meshSource->AddPoint(1, 0, 0),
  meshSource->AddPoint(0, 1, 0) );
meshSource->AddTriangle(
  meshSource->AddPoint(0, 0, 0),
  meshSource->AddPoint(1, 0, 0),
  meshSource->AddPoint(0, 0, 1) );

This class inherits from itk::MeshSource so it fits conveniently into a pipeline, but GetOutput() is always valid after every Add[Something]() call, and Update() is a no-op. It is not thread safe.

◆ AddHexahedron() [2/4]

template<typename TOutputMesh >

IdentifierType itk::AutomaticTopologyMeshSource< TOutputMesh >::AddHexahedron ( const IdentifierArrayType & pointIDs )

Add the hexahedron specified by the four points, and return its ID. If the points are p0, p1, p2, and p3, then the following additional cells (represented here as ordered tuples) are created (if they don't already exist) and associated as boundaries, in the order given:

Vertices: (p0), (p1), (p2), (p3), (p4), (p5), (p6), (p7).

Lines: (p0, p1), (p2, p3), (p4, p5), (p6, p7), (p0, p2), (p1, p3), (p4, p6), (p5, p7), (p0, p4), (p1, p5), (p2, p6), (p3, p7).

Quadrilaterals: (0, 1, 2, 3), (4, 5, 6, 7), (0, 1, 4, 5), (2, 3, 6, 7), (0, 2, 4, 6), (1, 3, 5, 7),

In particular, if the points are connected topologically as follows

  p4------------p5
  | \          / |
  |  p0------p1  |
  |  |       |   |
  |  |       |   |
  |  p2------p3  |
  | /          \ |
  p6------------p7

then you would call, for instance, meshSource->AddQuadrilateral(p0, p1, p2, p3, p4, p5, p6, p7).

◆ AddPoint() [2/3]

		CoordinateType	x5 = `0`
	)

Add the point with coordinates (x0, ..., xN) where N = PointDimension - 1. If N < 5, then any parameters after xN are ignored. If PointDimension > 6, then a point is generated with the first six coordinates equal to x0, ..., x5, and the rest set to 0.

◆ AddQuadrilateral() [2/4]

template<typename TOutputMesh >

IdentifierType itk::AutomaticTopologyMeshSource< TOutputMesh >::AddQuadrilateral ( const IdentifierArrayType & pointIDs )

Add the quadrilateral specified by the four points, and return its ID. If the points are p0, p1, p2, and p3, then the following additional cells (represented here as ordered tuples) are created (if they don't already exist) and associated as boundaries, in the order given:

Vertices: (p0), (p1), (p2), (p3).

Lines: (p0, p1), (p2, p3), (p0, p2), (p1, p3).

In particular, if the points are arranged geometrically as follows

  p0  p1

  p2  p3

then you would call, for instance, meshSource->AddQuadrilateral(p0, p1, p2, p3).
