Member Function Documentation

std::vector< Eigen::Vector3d > Normal_Grid::flat ( const std::vector< std::vector< Eigen::Vector3d > > &  _grid )

virtual

Calculate flat normals.

Parameters

_grid

the grid mesh

Returns

the normals for the grid

Exceptions

mondschein::exception

if a known exception is thrown during execution

This function calculates flat normals for _grid. That means one normal is calculated for every triangle of the grid. These normals are stored and returned in order of their calculation.

Definition at line 105 of file normgrid.cpp.

std::vector< Eigen::Vector3d > Normal_Grid::flat_inv ( const std::vector< std::vector< Eigen::Vector3d > > &  _grid )

virtual

Calculate inverse flat normals.

Parameters

_grid

the grid mesh

Returns

the normals for the grid

Exceptions

mondschein::exception

if a known exception is thrown during execution

Behaves like the above function but inverts the normals.

Definition at line 119 of file normgrid.cpp.

std::vector< Eigen::Vector3d > Normal_Grid::intermediate ( std::vector< std::vector< Eigen::Vector3d > >  _grid )

virtual

Calculate fintermediate normals.

Parameters

_grid

the grid mesh

Returns

the normals for the grid

Exceptions

mondschein::exception

if a known exception is thrown during execution

This function calculates intermediate normals for _grid. That means one normal is calculated for every vertex of the grid. These normals are stored and returned in order of their calculation.

Definition at line 133 of file normgrid.cpp.

std::vector< Eigen::Vector3d > Normal_Grid::intermediate_inv ( std::vector< std::vector< Eigen::Vector3d > >  _grid )

virtual

Calculate inverse fintermediate normals.

Parameters

_grid

the grid mesh

Returns

the normals for the grid

Exceptions

mondschein::exception

if a known exception is thrown during execution

TBehaves essentiallc like the above function but inverts the normals.
