performing a few operations on the GUI. The requirements
for this application are to create 3D “letter string” objects and
to prepare real objects in which markers are pasted. For
example, we prepare a real coffee cup and a marker, and we
create 3D letter string objects from multiple languages such as
“cup” (in English), “koppu”(in Japanese), “tasse” (in French).
Fig. 8 and Fig. 9 show the examples of our 3D letter string
label application.
