PTX

The PTX is a 3D file format used for representing 3D Point Clouds. The format contains only positional information (X, Y, and Z coordinates) for the individual points. The format is often used for digital elevation modeling of terrain for later processing in 3D modeling applications.

As the format only contains positional information, a common task is to convert this into a fully surfaced 3D model using methods such as Alpha Shapes or Delaunay Triangulation. The format can also be viewed without further processing in its raw format.
