# Terrain Processor: Area: Low-density Cluster (strip)

#### Task details

**Task name** : Area: Low-density Cluster (strip)

**Dll plugin name** : BITasksPlugin.dll

**Geometry type** : Polygon, PolygonM, PolygonZ

**Heightmap** : No

#### Description

Algorithm used for populating low-density areas. Objects are organized in linear clusters.

#### Task parameters

- **RANDOM SEED** - number used to initialize pseudorandom number generator.
- **CDENSHA** - The density of the filling in number of clusters for hectare.

#### Object prototype parameters

- **OBJECT** - Object's prototype name
- **MINHEIGHT** - Minimal size in %
- **MAXHEIGHT** - Maximal size in %
- **MINDIST** - Minimal distance in meters
- **GROUPID** - Cluster group id
- **MINCOUNT** - Minimal count of objects in one cluster
- **MAXCOUNT** - Maximal count of objects in one cluster

#### Usage

Similar to the "Area: Low-density Cluster (circle)", creates prolonged clusters of given width. Perfect for small tree groups, or for adding lines of undergrowth into forests.

#### Algorithm

For each shape (areal) do :

1. clusters_count = HECTARES * CDENSHA
1. For clusters_count :
   1. Get random prototypes group.
   1. Find position inside shape = cluster_center.
   1. For each object prototype do :
      1. prototypes_count = random MINCOUNT - MAXCOUNT
      1. For prototypes_count :
         1. Get random direction_vector with random length (0 - MAXCRADIUS) from cluster_center.
         1. If position = cluster_center + direction_vector id inside shape and condition MINDIST[n] is ok, then 3. else 1.
         1. Create new instance for object prototype in position.
