Detailed Description

template<typename PointT>
class pcl::ExtractPolygonalPrismData< PointT >

ExtractPolygonalPrismData uses a set of point indices that represent a planar model, and together with a given height, generates a 3D polygonal prism. The polygonal prism is then used to segment all points lying inside it.

An example of its usage is to extract the data lying within a set of 3D boundaries (e.g., objects supported by a plane).
