Constructor Details

ClipmapLevel

public ClipmapLevel(int levelIndex,
 Camera clipmapTestFrustum,
 int clipSideSize,
 float heightScale,
 TerrainCache cache)
             throws Exception

Creates a new clipmaplevel.

Parameters:

levelIndex - Levelindex of the clipmap. If is 0 this will be the finest level

clipmapTestFrustum - the clipmap test frustum

clipSideSize - Number of vertices per clipside. Must be one less than power of two.

heightScale - Maximum terrainheight and heightscale

cache - the terrain cache

Throws:

Exception - exception
