/**
* @class vtkOBJWriter
* @brief write wavefront obj file
*
* vtkOBJWriter writes wavefront obj (.obj) files in ASCII form.
* OBJ files contain the geometry including lines, triangles and polygons.
* Normals and texture coordinates on points are also written if they exist.
* One can specify a texture passing a vtkImageData on port 1.
* If a texture is set, additional .mtl and .png files are generated. Those files have the same
* name without obj extension.
* Alternatively, one can specify a TextureFileName pointing to an existing texture.
* In this case a .mtl file is generated pointing to the specified file.
*
