  With the development of 3D modelling techniques and AR techniques, the
traditional methods of establishing 2D to 3D relation is no longer sufficient
to meet the demand for complex models and rapid relation building. This
dissertation presents a prototype development implemented that creating many-
to-many correspondences by marking image and 3D model regions that can be used
to colouring 3D model by colouring image for the end user. After comparing the
three methods in the conceptual design, I chose the creating render textures
relation to further development by changing to Zeus bust model and connecting
the AR environment. The results of testing each part of the prototype shows the
viability of the creating render textures relation method. The advantages of it
are easy to build many-to-many relations and adaptable for any model with
properly UV mapping. But there are still three main limitations and future work
will focus on solving them, building a database to store relation information
data and printing 3D coloured models in real world.
