File format information for PTX and STL

ExtensionPTX
Full NamePoint Cloud
Type3D Model/Point Cloud
Mime Typetext/plain

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

When converting 3D Model/Mesh files using our [ey] converter we will attempt to convert color materials into a suitable format for use in the converted file.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

STL Converter Capabilities

When converting your PTX to STL our tool will attempt to accurately convert any color/material information.

Information for converting from PTX to STL

Your PTX file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our PTX 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As both PTX and STL support color material information our tool will also attempt to convert the color information too.

Frequently Asked Questions

How can I convert my PTX file to STL?

First click the "Upload..." button, select your PTX file to upload. Your PTX file will be uploaded to our servers. When the PTX to STL conversion has completed, you can download your STL file straight away.

How long does it take to convert my PTX to STL?

We aim to process all PTX to STL conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files, so please be patient.

How accurate is the conversion from the [x] 3D Point Cloud format?

Our PTX tool will read all the vertex information from your STL file and use only this information when creating the final STL file.
