Free Online PLY to CTM Converter

You can use our PLY to CTM conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch PLY to CTM converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your PLY file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted PLY file before this time.

Our 3D model PLY to CTM tool will load your PLY file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

Frequently Asked Questions

How can I convert my PLY file to CTM?

First, click the "Upload..." button and select your PLY file to upload. Your PLY file will be uploaded to our servers. When the PLY to CTM conversion has completed, you can download your CTM file right away.

How long does it take to convert my PLY to CTM?

We aim to process all PLY to CTM 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 CTM 3D point cloud format?

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

How does converting PLY to CTM work?

In order to successfully convert an PLY formatted file to the CTM format, our converter tools will perform several initial checks to ensure the file provided is indeed an PLY file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create PLY files to the exact specification.

Take your PLY file

The PLY file format can be either a text-based or binary format, meaning if its content is plain text, it is human-readable; otherwise, if it is binary, then it can only be edited with specialist PLY editing software. The data within the file, regardless of whether it is text or binary, contains the core elements that make up the 3D model, including vertices, faces and more. To guarantee efficient conversions, our tool will check all data that is contained within the PLY file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also that the generated CTM is smaller.

Convert the data from PLY to CTM

Now that the data from the PLY file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final CTM file format. Part of this process ensures checking the capabilities of the CTM format and removing any data that cannot be represented.

Save to the CTM format

At this point, the PLY to CTM conversion tool will have the 3D model in a state that is ready to be transferred to the CTM format. Our tool creates the CTM file, ensuring all the model data is present and is formatted to match the CTM file specification to ensure the file opens in compatible CTM file editors.

File format information for PLY and CTM

Extension	PLY
Full Name	Stanford Triangle Format
Type	3D Model/Point Cloud
Mime Type	application/octet-stream
Format	Text
Opens With	Blender, MeshLab

The PLY format, also known as the Standard Triangle Format, is a popular 3D model file format originally created by Stanford University in the 1990s as a means to store 3D model data in a flexible and expandable format. There can be both binary and ASCII text formats in PLY files.

Both binary and text formats share a common header section that defines what geometric attributes (such as vertices, normals, faces, and colors) are present in the data. It is also possible to specify custom data to be associated with a vertex or object face.

PLY files can be opened with a wide range of 3D editing software; for example, Blender can both import and export to the PLY format with no additional software required.

PLY Converter Capabilities

When converting 3D model or mesh files using our PLY converter, we will attempt to convert color materials into a suitable format for use in the converted file.

CTM Converter Capabilities

When converting your PLY to CTM, our tool will attempt to accurately convert any color or material information.

Information for converting from PLY to CTM

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