API Changes

  • the use of vtkMath::Random(), vtkMath::RandomSeed(), vtkMath::GetSeed(), vtkMath::Gaussian() is deprecated (there are error-prone and not deterministic (which is important for reproducibility of regression testing) as they use global static information. Instead, you should create an object of class vtkMinimalStandardRandomSequence to get a sequence of pseudo-random number following a uniform distribution. You should create an object of class vtkBoxMuellerRandomSequence to get a sequence of pseudo-random number following a Gaussian distribution.
