Convert Your 3D Mesh/Model PTX Files to OBJ

to

Our free and fast tool will convert most 3D mesh or PTX (Point Cloud) model files to a standard OBJ (Wavefront) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your PTX file click the Upload button above and select the file to convert. Once selected, the file will be converted to a OBJ file and will ready for download shortly afterwards. For more information about the PTX to OBJ conversion process see the conversion information section below for more information.

FAQ

How can I convert my PTX file to OBJ?

First click the "Upload..." button, select your PTX file to upload. Select any configuration options. When the PTX to OBJ conversion has completed, you can download your OBJ file straight away.

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

We aim to process all PTX to OBJ conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the PTX to OBJ conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features being added every week.

Is it safe to convert my PTX to OBJ on ImageToStl.com?

Yes, of course! We do not store the PTX file you submit to us. The resulting OBJ file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert PTX to OBJ on Windows, Linux, Android, iOS or Mac OS?

Yes! Our PTX to OBJ tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

Description

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.

Description

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.

As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.

PTX Notes

The PTX file format was designed to store vertex information only to allow the construction of simple Point Cloud models.
