selectively filter points
vtkMaskPoints is a filter that passes through points and point attributes from input dataset. (Other geometry is not passed through.) It is possible to mask every nth point, and to specify an initial offset to begin masking from. It is possible to also generate different random selections (jittered strides, real random samples, and spatially stratified random samples) from the input data. The filter can also generate vertices (topological primitives) as well as points. This is useful because vertices are rendered while points are not.

Special mode selector that switches between random mode types. 0 - randomized strides: randomly strides through the data (default); fairly certain that this is not a statistically random sample because the output depends on the order of the input and the input points do not have an equal chance to appear in the output (plus Vitter's incremental random algorithms are more complex than this, while not a proof it is good indication this isn't a statistically random sample

THIS ONLY WORKS WITH THE PARALLEL IMPLEMENTATION vtkPMaskPoints RUNNING IN PARALLEL. NOTHING WILL CHANGE IF THIS IS NOT THE PARALLEL vtkPMaskPoints. Determines whether maximum number of points is taken per processor (default) or if the maximum number of points is proportionally taken across processors (i.e., number of points per processor = points on a processor * maximum number of points / total points across all processors). In the first case, the total number of points = maximum number of points * number of processors. In the second case, the total number of points = maximum number of points.
