Houdini & UE4 programmed generation of mountains and multi vegetation scattering points

Program the overall process

Shape the terrain and mountains

use HF(HeightField) System noise , corrosion , Basic terrain for calculation of flow erosion

 

 

 

  extract Rock Layer and the Tree layer

Mainly to make use of HF Systematic mask by feature Feature extraction , Such as slope, etc , Then do some releasing HF Remap operation .

 

  Vegetation scattering point

  The terrain scatter point is mainly used for HF Systematic scatter, Can sprinkle points according to various characteristics .

  Trees

stay tree Layer Next, sprinkle some

 

shrub

Sprinkle around the trunk tree

  Fern

Sprinkle around the bush

stone

The stone is alone rock Layer for scattering , In the same way as the trunk tree

According to the effect :
