The ObjectFile class implements the Loader interface for the Wavefront
.obj file format, a standard 3D object file format created for use with
Wavefront's Advanced Visualizer (tm) and available for purchase from
Viewpoint DataLabs, as well as other 3D model companies.
Constructs an OrientedShape3D node with the specified geometry
component, appearance component, mode, axis, constant scale
enable flag, and scale
The specified axis must not be parallel to the Z
axis--(0,0,z) for any value of z.
The four row vectors that make up an orthogonal matrix form a basis,
meaning that they are mutually orthogonal; an orthogonal matrix with
positive determinant is a pure rotation matrix; a negative
determinant indicates a rotation and a reflection.
