Regarding mentioned issues, there can be derived steps or rules useful for
creation of 3D models. Those steps are taken over from Bandrova (
2001
), which
operates with the term of symbol for the 3D cartographic representation of real
objects.
1. The symbols, which are represented in 3D map, should be similar to the real
objects (according to photorealistic approach).
2. Minimum polygons should be used when a new symbol is built (for fast and
effective visualization).
3. The symbols should be created in their real dimensions (also for a reason of
photorealistic approach and also in spite of 2D maps, where symbols are often
exaggerated).
4. The symbols are designed for different purposes depending on user
s needs.
'
Not every time these rules can be abided, especially the rule number 3. Usually
for the purposes of quick visualization, the generalization of the object or the
replacement of the object with an object of lower dimension, need to be done.
For more detailed information how these rules are applied within this project see

Modeling of 3D Objects of Terez´n
The Terez
´
n Memorial is a very important place of historical events of our culture,
thus it is very important to commemorate these events even at present. Therefore
the main aim of the project is to geographically relate important events occurred in
Terez
´
n ghetto or important personages who lived in the ghetto during the Second
World War (2nd WW). Technically the paper further focuses on issues connected
with a creation of virtual 3D model of the Main Fortress and the Small Fortress of
Terez´n reflecting the state of the area in the period of the 2nd WW.
According to Blodig (
2003
), the first chapters in the history of Terez´n began to
be written at the end of the 18th century when Emperor Joseph II decided about the
construction of a fortress. Its purpose was to prevent enemy troops from penetrating
into the Bohemian hinterland and also protect the waterway along the river Elbe.
The fortress consisted of the Main and Small Fortress, as well as a fortified area
between the Old and New Eger. In June 1940 the Small Fortress in Terez´n was
turned into the Prague Gestapo Police Prison. The town itself—former Main
Fortress—was turned in November 1941 into a ghetto, an internment and transit
camp for the Jews. Deported to the ghetto were Jews from the then Protectorate of
Bohemia and Moravia, later also from Germany, Austria and other countries. At the
initiative of the government of the restored Czechoslovak Republic the Memorial of
National Suffering, later renamed to Terez´n Memorial, was established in the
places of wartime suffering of dozens of thousands of people in 1947. More
