A signed measure of the distance to the // surface is computed and sampled on a regular grid. The grid can then be // contoured at zero to extract the surface. The default values for // neighborhood size and sample spacing should give reasonable results for // most uses but can be set if desired. This procedure is based on the PhD // work of Hugues Hoppe: http://www.research.microsoft.com/~hoppe

// Description: // Specify the number of neighbors each point has, used for estimating the // local surface orientation. The default value of 20 should be OK for // most applications, higher values can be specified if the spread of // points is uneven. Values as low as 10 may yield adequate results for // some surfaces. Higher values cause the algorithm to take longer. Higher // values will cause errors on sharp boundaries. vtkGetMacro(NeighborhoodSize,int); vtkSetMacro(NeighborhoodSize,int);
