Graphics Language Transmission File
A file format developed and maintained by the Khronos Group organization, a consortium of industry leaders that creates open standards for graphics, media, and parallel computing. It is designed to facilitate the efficient storage and exchange of 3D models. It has the following features:
- GLTF Versions: There are two versions of the GLTF file format that are available:
- GLTF 1.0: Supports basic geometry, simple materials with textures, basic skeletal animations with joint hierarchies, scenes with a single root node and a hierarchy of child nodes, etc.
- GLTF 2.0: Supports more features, such as PBR (Physically Based Rendering) materials, Draco compression, advanced skeletal animations, skinning, morph targets, etc.
- ASCII and Binary Modes: By default, a GLTF file is saved in ASCII text mode, which is human-readable and easy to edit. To save a GLTF file with all referenced texture images in binary mode, the GLB file extension should be used. This reduces the file size and the number of files.
- Embedded Textures: GLTF/GLB files allow for a more streamlined and efficient way to manage 3D assets. By storing textures directly within the file, these formats eliminate the need for separate image files, making the 3D model self-contained and easier to distribute.
GLTF File Converters: Autoconverter and Automesher Application allow you to import and export GLTF and GLB files, and convert them into various other 3D file formats. Our products also support the use of Draco compression, which can significantly reduce the size of GLTF and GLB files without compromising visual fidelity.
Universal 3D File
An open-source compressed file format that was initiated by the 3D Industry Forum. U3D is designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. Here are some of the key features and advantages of U3D:
- 3D PDF Integration: U3D enables the generation of PDF documents that contain interactive 3D data. This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document. 3D PDF is a widely used and supported format that can be easily shared and distributed.
- U3D File Converters: Autoconverter and Automesher Application are capable of reading and writing to and from the U3D file format. This allows you to convert your 3D models from various formats, such as STL, OBJ, SKP, DAE, STEP, and others, to U3D and vice versa.
- IFX Conversion Library: Our U3D file converters use the publicly available open-source IFX conversion library provided by Intel. This library is a powerful and reliable tool that enables the conversion of 3D data to and from U3D.
