OBJ to U3D: Resources
Enclosed is a comprehensive list of resources related to the interoperability and exchange between OBJ and U3D files. These resources will prove invaluable in facilitating the conversion from OBJ to U3D files.
- Revolutionizing 3D File Conversion Beyond Online Tools
- Automesher Desktop Application for Windows to Convert 3D File Formats
- Convert 3D Mesh Files in the Batch Mode
- Autoconverter Uses Vertex Normals to Display Smooth Meshes
- Convert Smooth Edges in SketchUp SKP Files
- Enhancing 3D Models with Vertex Normal Smoothing in Autoconverter
OBJ File
The OBJ (Alias Wavefront Object) is a text-based file format that is widely used for 3D geometry objects across various 3D software programs. The OBJ file format can store named group objects, surface materials with transparent colors and texture images, and geometry primitives in the form of quads or triangles. However, it’s important to note that during the OBJ file conversion using our Autoconverter software, any quad primitives will be simplified into two triangles, as only triangular facets are supported. Additionally, due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp).
U3D File
The U3D (Universal 3D) file format is an open-source compressed format, initiated by the 3D Industry Forum. It’s designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. This format plays a significant role in the general 3D graphics industry, particularly in conjunction with 3D PDF technology. It enables the generation of PDF documents containing interactive 3D data from U3D files. Both of our U3D file converters, Autoconverter and Automesher Application, are capable of reading and writing to and from the U3D file format. This is made possible thanks to the publicly available open-source IFX conversion library provided by Intel. To streamline the process of generating 3D PDF documents, our converters create a standard TEX script that can be easily utilized with free LaTeX software.
