Let me give an example of what an Inventor file looks like:
#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)
}
}
}
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.
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.
