PLY to OBJ
Please find below the list of our other useful resources related to PLY and OBJ interoperability and exchange that could help you with the PLY to OBJ conversion.
PLY File
PLY (Polygon File Format or Stanford Triangle Format) is a file format developed to store three dimensional triangles with additional properties e.g. color, normals, transparency or texture coordinates. However, Autoconverter our PLY file converter can only read and write mesh geometry without the material properties, as in the PLY file they can vary between triangle vertices. You can save PLY files in a binary or ASCII text file format, with the preference for the binary version due to a significant PLY file size saving.
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. The OBJ file format is capable of storing named group objects, surface materials with transparent colors and 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 OBJ file conversion. It's important to mention that due to a textual format OBJ files will always be much bigger than the binary files, e.g. 3DS (3D Studio) or SKP (SketchUp).
