- relative : the maximal chordal deviation - epsilon max - is set to *s x the parameter* where *s* is the size
of the bounding box longest diagonal.
By default, the parameter is set to 0.001 and the maximum deviation is then set to 0.001 x s,
- which is equivalent to say that, for a bouding box of 1 meter, the maximal deviation is 1 mm.
+ which is equivalent to say that, for a bounding box of 1 meter, the maximal deviation is 1 mm.
- absolute : the maximal chordal deviation is the parameter itself. eg if the parameter equals 2, the maximal chordal deviation will be 2 (mm if the point coordonates are given in mm).
Following that criterion:
