Convert Your 3D Mesh/Model OFF Files to VTK

Our free and fast tool will convert most 3D mesh or OFF (Object File Format) model files to a standard VTK (Visualization Toolkit) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple OFF files; up to 25 files at a time can be converted.

100 MB
Uploads

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

Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable the storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shapes, and edge information, and it also has support for including color information. As the format is text-based, the files can become rather large, with no built-in compression options available.

OFF Notes

If your VTK file contains face colors, these will be imported and mapped where possible.

Description

The VTK file format is a 3D modeling and graphics format supported by the Visualization Toolkit. Created in the '90s, the Visualization Toolkit provides a series of data and visual tools for advanced 3D modeling applications. Some example functions of the toolkit include polygon simplification, mesh repair and smoothing, and more.

The format has evolved over the years. It started out as a simple text-based format that could be edited within a simple text editor. Additional features have been added over the years, with the most recent version of the format supporting an XML-based format.

VTK Notes

Any model converted to the VTK format will be stored in a triangulated mesh format.

Supported Features

  • Polygon mesh
  • Triangle strip-base mesh

How does it work?

Converting from the OFF file format to VTK can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your OFF file to a valid VTK 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source OFF File

In its simplest form, an OFF file is a plain text file containing human-readable 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

For more information regarding the OFF file format, please see this great article that goes into a lot of detail explaining the OFF format.

⇪

Step 2: Process File Data

With the OFF file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the VTK format.

⇪

Step 3: Saving to the VTK Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the VTK format.

Frequently Asked Questions

How does ImageToStl.com differ from other OFF file conversion websites?

Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full OFF file compatibility. Our bespoke file conversion tools offer full OFF file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your OFF file quickly and accurately with maximum compatibility.

I have several OFF files; can I batch convert my OFF to VTK?

Yes! Our OFF tool supports full batch conversions. You can upload up to 25 and OFF files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the VTK files individually or download them all in a single ZIP file.

How can I convert my OFF file to VTK?

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

How long does it take to convert my OFF to VTK?

We aim to process all OFF to VTK 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 OFF to VTK conversion?

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

Is it safe to convert my OFF to VTK on ImageToStl.com?

Yes, of course! We do not store the OFF file you submit to us. The resulting VTK file, once created is deleted 20 minutes after upload and the download link will expire after this time.

Do I need a high-spec. computer to use the OFF to VTK converter?

No. All our conversion tools process your OFF file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted VTK file quickly.

Can I convert my OFF to VTK on Windows, Linux, Android, iOS or Mac OS?

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

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our OFF conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

Can I get support with converting my OFF to VTK?

Yes. When you have converted your OFF to VTK, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
