WIDTH - specifies the width of the point cloud dataset in the number of Byĭefault, if COUNT is not present, all dimensions’ count is set to 1. Basically this is a way to introduce n-D histogram descriptorsĪt each point, and treating them as a single contiguous block of memory.

STL - a file format native to the stereolithography CAD software created by 3D Systems.PLY - a polygon file format, developed at Stanford University by Turk et al.Numerous formats to describe arbitrary polygons and point clouds acquired using Graphics and computational geometry communities in particular, have created PCD is not the first file type to support 3D point cloud data. Support some of the extensions that PCL brings to n-D point cloud processing. The PCD file format is not meant to reinvent the wheel, but rather toĬomplement existing file formats that for one reason or another did not/do not
