Task details

Task name : Heightmap: Perlin Noise

Dll plugin name : BITasksPlugin.dll

Geometry type : Polygon, PolygonM, PolygonZ

Heightmap : Yes


Description

Algorithm adds perlin noise in terrain heightmap. It uses Shapefile as mask polygons. Perlin noise on Wikipedia.

Task parameters

  • Amplitude - Maximal +- height added to terrain heightmap.
  • Scale - Perlin noise mapping scale.


Usage

Good to for creating some terrain corrugation within a particular area, e.g. more rugged terrain in a forest offering some additional cover to infantry. Gentle noise adds natural feel to meadows or brownfield.

Algorithm

  1. Load heightmap
  2. For each shapefile polygon
    1. For each heightmap point in polygon
      1. Get Perlin noise value and add it to height in heightmap
