Member Data Documentation

template<class T >

float lti::delaunayTriangulation< T >::parameters::epsilon

This value is used for determining when a point falls on an edge.

Thus the construction of the triangulation can be influenced quite strongly by this value.

Note that the values depends on the given data.

Default: 0.001. Works well for pixel position ranges

Referenced by lti::delaunayTriangulation< T >::parameters::copy(), lti::delaunayTriangulation< T >::parameters::parameters(), lti::delaunayTriangulation< T >::parameters::read(), and lti::delaunayTriangulation< T >::parameters::write().

template<class T >

float lti::delaunayTriangulation< T >::parameters::specialPointsFactor

The algorithm uses a virtual triangle consisting of three special points.

It must at least include all given points. However, the distance of these points from the actual points influences the bahaviour of the algorithm with respect to small dents in the convex hull.

A large value will give you the complete, correct Delaunay triangulation. A small value excludes triangles that share one edge with the convex hull and have a 'large' angle opposite that edge. This behavior can be useful in some applications where 'degenerate' triangles are not useful.

Default: 100. Gives the correct result for most applications
