In X3DOM, a shape such as Box, Cone, and Sphere is always created at the center of the coordinate system. The
size of the shape can be modified,
but the location is always centered at (0,0,0). To move a shape to another location, a transformation needs to
be applied. See slides for
the different kinds of affine transformations: translation, rotation, and scaling.
