// .NAME vtkSurfaceReconstructionFilter - reconstructs a surface from unorganized points
|
|
// .SECTION Description
|
|
// vtkSurfaceReconstructionFilter takes a list of points assumed to lie on
|
|
// the surface of a solid 3D object. 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

// 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.
