Detailed Description

Generate an ordered mesh from an OrderedPointSet.

Create a mesh from an OrderedPointSet, using the ordering information to generate a triangulation of the vertices. Triangulation relies upon the ordering information inherent to the OrderedPointSet and is independent of the actual 3D position of vertices.

Vertices are grouped into "squares" according to their position within the ordering matrix. These squares are then subdivided into two triangles and added to the output mesh.

Vertex normals are computed using CalculateNormals.

add_cell_()

void volcart::meshing::OrderedPointSetMesher::add_cell_ ( std::size_t  a, std::size_t  b, std::size_t  c  )

private

Add a face to the output mesh.

Parameters

a	ID for the first vertex in the face
b	ID for the second vertex in the face
c	ID for the third vertex in the face

getOutputMesh()

ITKMesh::Pointer volcart::meshing::OrderedPointSetMesher::getOutputMesh ( ) const

inline

Get the generated mesh.

setComputeTriangulation()

void volcart::meshing::OrderedPointSetMesher::setComputeTriangulation ( bool  b )

inline

Set whether to compute a triangulation from point ordering.

When enabled, use point ordering to generate a triangulation. Otherwise, the resulting mesh is only filled with vertices.

Default: Enabled

setPointSet()

void volcart::meshing::OrderedPointSetMesher::setPointSet ( const PointSet &  points )

inline

Set the input OrderedPointSet.
