If the terrain is based on a real world location then reference material such as texture maps and height data are obtained and used for reference.
A base model is created and a texture map is applied, similar to what you see above.
From there, additional 3D models such as trees, plants, grass, clouds and atmospheres can be added at extra time and cost to improve the appearance of the final output.
Re-create real world terrains.
Create imaginary terrains.
Create a hybrid of the two.
Utilise satellite height data.
Add additional 3D models.
Control camera fly throughs.
Raise oceans and much more.
Fractal based terrains can also be created which offer unlimited detail, but have "other" limitations.
Documentaries, news channels, military, aviation personal, geologists, weather channels, security firms, site surveys, defence sectors, geologists, and anyone with an existing or emerging need to visualise and control large and accurate, 3D terrains.
Underwater and Planets included.
Dynamic 3D is especially keen to implement this type of solution into security, police and defence sectors.
