Alias Wavefront Object File
A text-based file format that is extensively used for 3D geometry objects across a variety of 3D software programs. Some of the benefits and features of OBJ files are:
- Named Group Objects: OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.
- Surface Materials: The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.
- Geometry Primitives: OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our Autoconverter software, any quad primitives will be simplified into two triangles, as only triangular facets are supported.
- OBJ File Size: Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.
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.
