Constructor & Destructor Documentation

CalculateNormals()

volcart::meshing::CalculateNormals::CalculateNormals ( const ITKMesh::Pointer &  mesh )

explicit

Parameters

mesh	Input Mesh whose normals you want computed

Member Function Documentation

assign_to_mesh_()

void volcart::meshing::CalculateNormals::assign_to_mesh_ ( )

private

Assign the summed normals to the output mesh.

Takes the summed normals for each vertex and assigns them to the corresponding vertex in the output mesh.

compute_normals_()

void volcart::meshing::CalculateNormals::compute_normals_ ( )

private

Compute normals for each vertex.

For each face, computes the normal to that face and adds the resulting vector to a sum vector for each vertex in that face.

getMesh()

ITKMesh::Pointer volcart::meshing::CalculateNormals::getMesh ( ) const

inline

Get the output mesh with computed normals.

Definition at line 49 of file CalculateNormals.hpp.

setMesh()

void volcart::meshing::CalculateNormals::setMesh

(

const ITKMesh::Pointer &

mesh

)

Set the input mesh.

Parameters

mesh	The mesh for which normals will be calculated

Member Data Documentation

output_

ITKMesh::Pointer volcart::meshing::CalculateNormals::output_

private

Mesh with calculated normals.
