name: name of the object type: type of objects. Valid types are "planar" or "3D" faces: number of faces the model is composed of (usually 1-6 for planar objects -actually planar or cube-shaped-, or any number for 3D) dimensions: dimensions of the object. Fields under this node only appear depending on the type of the object + scale (3D): scale factor applied to the 3D points obtained when Bundler and PMVS are run on the face images. This value is useful to reconstruct the model + width, height, depth (planar): real dimensions in metres of a planar/cuboid object. For actually planar objects, depth is 0 (or may not appear). What dimension is associated with each concept depends on the application that created the model face (planar): contains information about the dimensions of each face. This information is used to reconstruct the model + index: index of the face [0..N) + width, height: real dimensions in metres of the planar face + oTf: 4x4 transformation in row-major order from the object frame to the face frame. oTf is the identity matrix when the object is actually planar (only one face)
