Description
A reference scale is associated with each terrain pyramid level. This is the maximum display scale at which a pyramid level is used when displaying a terrain in a map. At a larger display scale (i.e. more zoomed in) a more accurate pyramid is used.
The input index represents the pyramid level desired, from finer to coarser resolution, excluding the full resolution level. So, index 0 refers to the pyramid level with the smallest ZTolerance that is greater than 0.0. The valid index range is 0 to ITerrain.ZToleranceCount-1.
The value passed for newScale is the denominator of the scale. For example, to define a pyramid used for displays at scales up to 1:24000 pass a value of 24000.
Modifying the maximum scale for a pyramid does not necessitate a rebuild of the terrain.
