void operator= ( const triSurface2DCheck &  )

private

Disallow default bitwise assignment.

is2DSurface()

bool is2DSurface

(

)

const

checks if the surface is a 2D triangulation

the smallest eigenvalue must be zero in case all face normals lie in a plane

calculate the plane normal as a cross prduct of the two eigenVectors spanning the plane

check if the plane is in the x-y plane of the coordinate system

this could be a 2D surface, but it is not in the x-y plane

check if the points in the 2D surface have uniform z coordinates
