reduce the number of triangles in a vtkPolyData mesh
vtkBinnedDecimation is a filter to reduce the number of triangles in a triangle mesh represented by vtkPolyData. It is similar to vtkQuadricClustering in concept, although it is performance accelerated: it does not use quadric error metrics to position points in the bins, plus it is threaded. (See vtkQuadricClustering for more information.) It also takes some short cuts in the interest of speed: it limits the binning resolution to no more than 2^31 bins; and it can (optionally) reuse the input points in the output (to save memory and computational costs).
A high-level overview of the algorithm is as follows. Points are binned into a regular grid subdivided in the x-y-z directions. The idea is to combine all the points within each bin into a single point which is then used by the output triangles. Four options are available to generate the output points. If the input points are to be reused as the output points, then all points in the same bin simply adopt the coordinates of one of the selected points in the bin (and thus all points in the bin take on the same output point id). Alternatively, if new output points are to be generated, then either one point is selected; the centers of occupied bins can be used as the output point coordinates; or an average position of all points falling into the bin can be used to generate the bin point. Finally, triangles are inserted into the output: triangles whose three, binned points lie in separate bins are sent to the output, while all others are discarded (i.e., triangles with two or more points in the same bin are not sent to the output).
To use this filter, specify the divisions defining the spatial subdivision in the x, y, and z directions. Of course you must also specify an input vtkPolyData / filter connection. Higher division levels generally produce results closer to the original mesh. Note that for performance reasons (i.e., related to memory), the maximum divisions in the x-y-z directions is limited in such a way (i.e., proportional scaling of divisions is used) so as to ensure that no more than 2^31 bins are used. Higher divisions have modest impact on the overall performance of the algorithm, although the resolution of the output vtkPolyData is affected significantly (i.e., many more triangles may be generated).

Four options exist for generating output points.
1) Pass the input points through to the output; 2) select one of the input points in the bin and use that; 3) generate new points at the center of bins (only center bin points used by the output triangles are generated); and 4) generate new points from the average of all points falling into a bin and used by output triangles. Note that 1) can result in many, unused output points, but tends to be fastest for small numbers of bins. This can impact rendering memory usage as all points are typically pushed into the graphics hardware. Options 2-4 produce only points used by the output triangles but generally take longer (for small numbers of bins), with speeds slowing in order from options 2 through 4. In terms of quality, option 4 (BIN_AVERAGES) produces the best output; options 1) and 2) produce decent output, with option 3) (BIN_CENTERS) producing a voxelized-like result (which is quite useful for illustrative purposes). Note that for very large numbers of bins (say number of divisions > 500^3), then algorithm 4) BIN_AVERAGES scales better, i.e., is likely faster and produces better results.

void vtkBinnedDecimation::SetNumberOfXDivisions | ( | int | num | ) |
Set/Get the number of divisions along each axis for the spatial bins.
The number of spatial bins is NumberOfXDivisions*NumberOfYDivisions* NumberOfZDivisions. The filter may choose to ignore large numbers of divisions if the input has few points and AutoAdjustNumberOfDivisions is enabled. Also, the maximum number of divisions is controlled so that no more than 2^31 bins are created. (If bin adjustment due to the limit on the number of bins is necessary, then a proportional scaling of the divisions in the x-y-z directions is used.) This API has been adopted to be consistent with vtkQuadricClustering.
