- - relative : the maximal chordal deviation - epsilon max -is set to 0.001 x the parameter. by default, the parameter is set to 0.1 and the maximum deviation is also 0.1 x 1/1000 * the size of the bounding box, which is equivalent to say that, for a bouding box of 1 meter, the maximal deviation is 0.1 mm.
+ - 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.
