Questions tagged [.obj]

A text-based file format that stores 3d geometry.

The .obj file format was developed originally by Wavefront Technologies for their flagship 3d graphics software The Advanced Visualizer.

It is a text-based format that is human readable and simple to parse. .obj can only store the position, UV coordinates, and normal of a vertex. Mesh hierarchies and animation of any kind are not supported. Free-form geometry like curves and surfaces are defined in the specification, but are not used that often, and as a result, not commonly implemented in parsers.

Generate header of view .obj file

Is there a way to generate a c++ header file for an .obj file? Or perhaps is there an utility that can view .obj files. I've already found objconv that converts between formats, but I can't find any .h generator/viewer.

.obj file format - alternates between different data types

I'm writing a method to parse the data in wavefront obj files and I understand the format for the most part, however some things are still a bit confusing to me. For instance, I would have expected most files to list all the vertices first, followed…
