Convert OBJ file

OBJ OBJ File

OBJ (Alias Wavefront Object) is a text based file format for 3D geometry objects which is very popular and widely supported by many 3D software programs. OBJ file format is capable of storing named group objects, surface materials with transparent colors or texture images, and quads or triangles as geometry primitives. However our Autoconverter software will simplify every OBJ quad primitive with two triangles as only triangular facets are supported during the file conversion. It's important to mention that due to a textual format OBJ files will always be significantly bigger than the binary files e.g. 3DS (3D Studio) or SKP (SketchUp).


U3D U3D File

U3D (Universal 3D) is an open source compressed file format initiated by the 3D Industry Forum to store three dimensional triangular meshes with the additional properties e.g. color, transparency or texture coordinates for the general 3D graphics industry. The U3D file format is mostly used in combination with the 3D PDF technology which allows you to generate PDF documents containing interactive 3D data from the U3D files. Autoconverter and Automesher Application, our U3D file converters can read and write to and from U3D file format thanks to the publicly available open source IFX converter library provided by the Intel company. To simplify generation of 3D PDF documents our converters create a common TEX script which can be easily used to generate a PDF document with the standard and free LaTeX software.
