Is the WorldBuilder terrain model based on fractals?
WorldBuilder uses skeleton lines to specify thelandscape surface. Skeletons give full control over the surface and allow the adding of exact features at precise locations with ease. Also, skeletons give comprehensive and compact representation of the terrain geometry. Skeletons are reusable. The WorldBuilder CD contains a large library with ready-to-use landscape forms. Skeleton-based surfaces can also be modified by applying different procedures like water erosion, profiling by gray-scale map or mesh-based footprints. Footprints are especially useful for merging architecture with landscape. Finally, real-world elevation data can be imported via DEM files.
