Another important possibility it is to guide the user and to link, for example to a text, some particular views to
visualize the object in a certain way to emphasize some property of it. We created special named view such
as top, front, left right in perspective or in orthogonal mode, to improve the public enjoyment of 3D model by
interactivity. We decided to show the model not only in a render mode, where the hidden lines are invisible,
but we chose to visualize the model showing its structure.
We carefully planed the named views that we considered more useful for visualization and interaction.
We are testing the best way to link to 3D PDF file some other information to compare the original look of
Cuma's monumental buildings and landscape with they look today.
We have done this by using action options, they let us to create a conceptual link between 3D model and
some other information. We think this is an useful alternative to classic animation. However, this kind of
representation is a dynamic one, in fact, when we change from one named view to another, the 3D PDF
visualization mode automatically creates an animation[7].
There are a lots of benefits to use actions, first of all we can update and expanded the database linked to 3D
model in an easy way and we improve the access to 3D exploration of the model for people who no
experience of 3D.
So, one of the most important target of our research is to test a new strategy to improve public enjoyment
using 3D PDF files.
Another problem to solve is to simplify the 3D model to create 3D PDF file. We have to reduce the
complexity of the 3D model choosing details, texture in an adequate way.. The target is to have a 3D model
file not too large without losing its communication characteristic. In this case it means that less could be
more.
6. Conclusions
The videos represent one of the most powerful tools to communicate the story of an archaeological site.
Animation are always an alternative for visualization of 3D model but lack interactivity.
The availability of platform such as the iPad and iPhone has improved the way we deal with digital data.
