Detailed Description

generate points from vtkPolyData

vtkPolyDataPointSampler generates points from input vtkPolyData. The filter has two modes of operation: random point generation, or regular point generation. In random generation mode, points are generated in each polygonal entity using a random approach. In regular generation mode, the points are placed approximately a specified distance apart. Optionally, the points attributes can be interpolated from the generating vertices, edges, and polygons.

In regular point generation mode, this filter functions as follows. First, it regurgitates all input points, then it samples all lines, plus edges associated with the input polygons and triangle strips to produce edge points. Finally, the interiors of polygons and triangle strips are subsampled to produce points. All of these operations can be enabled or disabled separately. Note that this algorithm only approximately generates points the specified distance apart. Generally the point density is finer than requested.

In random point generation mode, this filter functions as follows. First, it randomly regurgitates all input points (if enabled), then it randomly samples all lines, plus edges associated with the input polygons and triangle strips to produce edge points (if enabled). Finally, the interiors of polygons and triangle strips are randomly subsampled to produce points. All of these operations can be enabled or disabled separately. Note that this algorithm only approximately generates points the specified distance apart. Generally the point density is finer than requested. Also note that the result is not truly random due to the constraints of the mesh construction.

Warning
Although this algorithm processes general polygons. it does so by performing a fan triangulation. This may produce poor results, especially for concave polygons. For better results, use a triangle filter to pre-tesselate polygons.
In random point generation mode, producing random edges and vertex points from polygons and triangle strips is less random than is typically desirable. You may wish to disable vertex and edge point generation for a result that is closer to random.
Point generation can be useful in a variety of applications. For example, generating seed points for glyphing or streamline generation. Another useful application is generating points for implicit modeling. In many cases implicit models can be more efficiently generated from points than from polygons or other primitives.
When sampling polygons of five sides or more, the polygon is triangulated. This can result in variations in point density near tessellation boundaries.
