    31  The dots shown in Blender around the surface are a Blender issue -- those  dots should not be shown.  For example, using a VRML web viewer does not  show the dots
    32 
    33      https://imagetostl.com/view-vrml-online#convert
    34 
    35  Maybe Blender is showing them just to indicate that the file does contain  extra vertices although the file does not render them.  The reason there  are extra vertices is because the volume radial preset did a hide dust  which hid part of the surface.  But that does not delete the dust part of  the surface and that is why the vertices (but not the triangles) for the  dust appear in the VRML file.
    36 
    37  Saving a .glb file by default centers the output at 0,0,0 while saving  VRML does not do that centering.  That is one reason they will not align.
    38  But it appears the rotation is different in your image.  But in the web  vrml viewer I mention above the orientation exactly matches the .glb and  the original map file.  Maybe you rotated the scene before you saved the  .wrl file and that is why it is showing a different orientation.
    39 
    40  If you want the VRML output to center I can probably add an option for  that.  If you need the unshown dust vertices to actually be deleted from  the file, I could probably add some option to do that too.
