Let me give an example of what an Inventor file looks like:
As you can see, it is a plain text (ASCII) file, with nice commments in it. The Separator command acts as logical paranthesis. You can view the file here.#Inventor V1.0 ascii Separator { Separator { Material { diffuseColor 0.0 0.0 1.0 # Blue transparency 0.25 # 25% transparent } Sphere { # A sphere radius 1.5 # of radius 1.5 } } Separator { Transform { translation 3.0 0.0 0.0 # We move a bit } Material { diffuseColor 0.0 1.0 0.0 # Green } Cube { # A Cube (of default dimensions) } } }
Now, if we in the above Inventor 3D scene replaces ``Inventor'' with ``VRML'' in the first line, we have a VRML 3D scene! You can view it here.
