The file format is ".obj" Example The program ~cs307/pub/tw/bin/show-object will read in an .obj file, define the twBoundingBox based on the bounding box of the object, and display it. There are some .obj files in ~cs307/pub/tw/objects and ~cs307/pub/tw/tutors/data, so try viewing some of those. You give the filename on the command line, thus:

How are OBJ files formatted?
The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.

What is the difference between STL and OBJ?
STL files store objects as sets of vertices joined by edges to make triangular faces. OBJ files store 3D information as a list of vertices joined by edges, and unlike STLs, they support polygonal faces that allow for a closer representation of the original geometry.

What is an OBJ File?
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.
History
Wavefront Technologies created OBJ file format for its Advanced Visualizer application to store geometric objects and 3D data. Its version 2.11 is superseded by a newly documented version 3. The file format is open and has been implemented by other vendors for their 3D graphics application.
OBJ File Format
In 3D objects, encoding the surface geometry is a challenging job that OBJ file format accomplished very well. This format is quite versatile as it offers a number of choices to encode surface geometry. Following are three allowed formats having their own benefits and shortcomings:
What is a vertex command?
The vertex command, this specifies a vertex by its three coordinates. The vertex is implicitly named by the order it is found in the file. For example, the first vertex in the file is referenced as '1', the second as '2' and so on. None of the vertex commands actually specify any geometry, they are just points in space.
What command specifies a normal vector?
They really don't tell you anything by themselves, they must be grouped with a vertex in a 'f' face command. The vertex normal command specifies a normal vector. A lot of times these aren't used, because the 'f' face command will use the order the 'v' commands are given to determine the normal instead.
What is a G name?
g name. The group name command specifies a sub-object grouping. All 'f' face commands that follow are considered to be in the same group. usemtl name. The use material command lets you name a material to use. All 'f' face commands that follow will use the same material, until another usemtl command is encountered.
What direction do you flip a normal in 3D?
They are assumed to be in counter-clockwise direction. If you aren't using vn's to specify the normal and you wanted to 'flip the normal' you would reverse the order of the verticies. In most 3D programs, if the normal points the wrong way, there will appear to be a hole in the object.
