Value parameters
- format
-
the optional file format specification. For csv files, it is such as
delimiter=\t,header=true,comment=#,escape=,quote=". For json files, it is the file mode (single-line or multi-line). For avro files, it is the path to the schema file. - path

Reads a Wavefront OBJ file.
Reads a Wavefront OBJ file.
Attributes
Reads a Wavefront OBJ file. The OBJ file format is a simple format of 3D geometry including 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. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. OBJ coordinates have no units, but OBJ files can contain scale information in a human-readable comment line.
