Unlike WS2.0 which has a fixed terrain mesh, VPB uses different terrain meshes with different level of detail (LoD) depending on the distance of the viewer from the particular piece of terrain. | Unlike WS2.0 which has a fixed terrain mesh, VPB uses different terrain meshes with different level of detail (LoD) depending on the distance of the viewer from the particular piece of terrain. | ||

Virtual Planet Builder provides a variety of settings that have a big impact on the eventual terrain mesh. The two main settings (the number of LoD levels, and the ratio of the LoD radius and maximum visible range), have a huge impact on the number of vertices, how the terrain looks, LoD "popping", and framerate. | Virtual Planet Builder provides a variety of settings that have a big impact on the eventual terrain mesh.

These results suggest that using 7 LoD Levels and a radius of "3" will provide a good balance, with high terrain quality and good frame-rate. | These results suggest that using 7 LoD Levels and a radius of "3" will provide a good balance, with high terrain quality and good frame-rate. | ||
