Yes, you are correct. The .x3d holds all the naming and transform information
of the Blender types. As long as you stick with Blender primitives (blobs,
spheres, torus, cube, etc. the output file is simple to parse. I use it to
export point arrays for POV lathes, sweeps, prisms, 2D arrays. I wrote a
converter that reads the .x3d and writes POV syntax. Attached shows spheres
renamed as 'pointData in Blender... I convert the points into 'mixed array' to
be used in a construction loop.


Currently working on some sci-fi tower forms

// convert .x3d

#declare pointDataCount = 12 ;
#declare pointArray = array mixed [pointDataCount][2] ;
#declare pointArray[0][0] = <21.561, -4.214, 0.159>  ;
#declare pointArray[0][1] = 2.285 ;
#declare pointArray[1][0] = <24.891, -4.027, 0.112>  ;
#declare pointArray[1][1] = 2.162 ;
#declare pointArray[2][0] = <28.244, -3.671, 0.020>  ;
#declare pointArray[2][1] = 1.930 ;
#declare pointArray[3][0] = <31.605, -3.120, -0.142>  ;
........



#declare node = sphere {<0,0,0> 1.6} ;

#declare arm_right =
intersection {
    union {
        #for (i,0,pointDataCount-1)
            object {node scale pointArray[i][1]*.9 translate pointArray[i][0]}
        #end
        material {M_red_metal}
    }
}
