The scene files for Machine Problem 3 are similar to the scenefiles for the last machine problem. However, the vertex normals were added to the end of the file. Each line of this new section is a direction vector for the vertex at the same index of vertex array.

You are responsible for placing a light in your scene. Make sure it shows off the specular highlights of the object. Do not place the light directly behind the object, or you will just have a black scene.
