Method SetRelativeGeometricTolerance

Common/DataModel/vtkGeometricErrorMetric.cxx:54–94

------------------------------------------------------------------------------ Description : Set the geometric accuracy with a value relative to the bounding box of the dataset. Internally compute the absolute tolerance. For instance 0.01 will give better result than 0.1. \pre valid_range_value: value>0 && value<1 \pre ds_exists: ds!=0

// \pre valid_range_value: value>0 && value<1
// \pre ds_exists: ds!=0
