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.
