Convert Your 3D Mesh/Model X Files to GLTF

Our free and fast tool will convert most 3D mesh or X (Direct X File) model files to a standard GLTF (Graphics Language Transmission Format) 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 X files; up to 25 files at a time can be converted.

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

How to Convert your X to GLTF Online?

Here are two simple steps to convert your X to GLTF.

Upload a X

Click the "Upload a X File" button and select a X to upload. The maximum file size is 100MB.

Download your GLTF

Click the download link once completed to receive your GLTF file.

File Format Information for X to GLTF

ExtensionX
Full NameDirect X File
Type3D Model
Mime Typetext/plain
FormatText
ToolsX Converters, 3D Model Voxelizer, Create X Animation, Text to X, X Viewer

Description

The X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API, Direct X, back in 2002. The format has evolved over the years; however, in 2014, the X file format was deprecated in favor of newer, more capable formats such as FBX.

The format is a simple text-based file capable of storing 3D mesh information such as vertices, faces, normals, and material information. In addition to basic 3D information, the format can also store animations with the X file format, which is primarily used in the development of games.

X Notes

If your GLTF file contains textures, these will be ignored. If a material contains color information, this will be translated where possible.

Description

The GLTF file format, which can also have the GLB file extension depending on whether the content is binary or text, JSON is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLTF format is an open standard that is maintained by the Khronos Group.

How does it work?

Converting from the X file format to GLTF 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 X file to a valid GLTF 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source X File

In its simplest form, an X 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.

When our tool reads this 3D data, all we are interested in are the vertices, faces, normals, materials, and textures, as this is the only data that can be accurately converted into the final GLTF file.

The X file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an GLTF file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the X file.

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

Step 2: Process File Data

With the X 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 GLTF format.

Step 3: Saving to the GLTF 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 GLTF format.

Along with the completed GLTF file, any textures that were present in the original X file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.

Frequently Asked Questions

How can I convert my X file to GLTF?

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

How long does it take to convert my X to GLTF?

We aim to process all X to GLTF 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 X to GLTF 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 X to GLTF on ImageToStl.com?

Yes, of course! We do not store the X file you submit to us. The resulting GLTF file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Do I need a high-spec. computer to use the X to GLTF converter?

No. All our conversion tools process your X 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 GLTF file quickly.

Can I convert my X to GLTF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our X to GLTF 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 X 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 X to GLTF?

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