OBJSONModel
bounds is an array of doubles containing 6 values used to determine the bounding box of the model.
boxes is a 2D array containing collision boxes for the model, each entry is formatted the same way as bounds.
faces gets more complicated, each entry in the faces array contains data to create triangles on a given face.
Face
texture specifies the texture to use for the face, just says whether or not it uses cladding.
vertices specifies a list of vertices available to draw for the face, this includes the normals and uvs.
triangles specifies a list of indexes in vertices to use to create a triangle.
