| Abstract: | The modeling and real-time rendering technology of teal large area terrain database is one of the difficulties for visual system of military simulation. The key technologies were studied including Level of Detail, Virtual Texture, Texture Mapping, Dynamic Paging Strategy, Large Area Database Management. Then a solution was proposed that utilized the above technologies, and generated the large area terrain by Creator Terrain Studio and rendered the terrain using Vega Prime and LADBM. The experiment result shows perfect visual effect in the real-time environment. |
