1. Consequently the probabilistic calculations made the pseudo random option with previous versions up to PiR3D v4 1 5 will not produce the same results when they will be re run with RocPro3D The use of this new random number generator now allows to perform true random or pseudo random parallel computations New meshing options Models of 2D type Models created from a 2D profile can be transformed into a DTM type model see button 2D gt 3D in the 2D profile sub tab of the Topo tab e This is then used to perform all editing operations available for DTM type models especially resampling and adding a nois ffect s below DTM type models e Addition of buttons to create topo points or contours Mesh noising of DTM type models s DTM Edition dialog e For DTM type Mesh it is now possible to add a noise to the DTM in the DTM Edition dialog This noising consists to alter the Z coordinate elevation of the mesh points by applying a variation This noise is defined by a random variation dz dz or Gaussian centered standard deviation sig_z around its original value e The noise is applied to all grid points falling within the selection area shown by the red rectangle in the 2D view thus allowing to apply when necessary various noises to different areas The application of a noise can amongst others be useful in the study of theoretical 2D profil2.
