// .OBJ Loader
// by SAITO <http://users.design.ucla.edu/~tatsuyas>
// Placing a virtual structure represented as mathematically
// three-dimensional object.
// SModel.load() reads structure data of the object stored
// as numerical data.
// SModel.draw() gives a visual form to the structure data.
// processing standard drawing functions can be used to manipulate
// the visual form to create deep visual experiences.
