Making Visualization 1
Import of SOSI Data The original data for the
terrain are stored on SOSI format and must be
imported.
Triangulization The next Step in the process is
to make triangulization from those data to be
able to make the elevationgrid.

Making Visualization 2
Elevation Grid From the triangulization the
elevation grid is approximated.
Texture from Orthographic Photo The elevation
grid allow the use of orthographic photo as
texture.

Making Visualization 3
Apply LOD to Terrain The final step for the
terrain is to split the grid into smaller bits,
to make the model lighter.
Add Buildings From SOSI When the terrain is done,
the data for the buildings are imported into the
model.

Final Result
Model of Fredriksten Fortress with buildings,
texture and LOD.
