What file formats are supported in wavefront 3D software?
OBJ files are used by Wavefront’s Advanced Visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format.
What is the maximum size of an OBJ file?
04/03/2020 · The format was created in the 1980s by Wavefront Technologies for its Advanced Visualizer animation software (Autodesk Maya has since replaced Advanced Visualizer). The file extension OBJ comes from the name Wavefront OBJect (the full name is rarely used). Other companies have adopted the OBJ format for use in their applications.
How do I describe a face in an OBJ file?
Object Files (.obj) Object files define the geometry and other properties for objects in Wavefront's Advanced Visualizer. Object files can also be used to transfer geometric data back and forth between the Advanced Visualizer and other applications. Object files can be in ASCII format (.obj) or binary format (.mod).

Overview
File format
Anything following a hash character (#) is a comment.
An OBJ file may contain vertex data, free-form curve/surface attributes, elements, free-form curve/surface body statements, connectivity between free-form surfaces, grouping and display/render attribute information. The most common elements are geometric vertices, texture coordinates, vertex normals and polygonal faces:
Material template library
The Material Template Library format (MTL) or .MTL File Format is a companion file format to .OBJ, also defined by Wavefront Technologies, that describes surface shading (material) properties of objects within one or more .OBJ files. A .OBJ file references one or more .MTL files (called "material libraries"), and from there, references one or more material descriptions by name. .MTL files are ASCII text that define the light reflecting properties of a surface for the purposes of computer …
