Flats . Lowlands

Lowlands represent a large-scale, planar terrain typology with minimal change in elevation across a surface (see Fig. 16.9). This lack of change produces few boundaries and makes it extremely difficult to perceive shifts in topography, requiring strategies that focus on highlighting contrast. Lowlands require shifting levels of detail; while some areas require high refinement to reveal variation, other areas require very little detail, due to the absence of diversity. The large scale and lack of variation make lowlands easy to derive from most any creation method. The essential moments where small changes take place can be accomplished through localized tessellation done manually or through optimization modifiers.
