|Scene with many forest types - Helena National Forest, Montana|
|Deer Lodge National Forest, Montana|
Inspired by some of the beautiful forests of the Rocky Mountains, I decided to see if this system could also be used to render similar rock formations and mixed forests. With not too much effort I was able to implement a similar scene supporting multi texturing and different tree types (in this case, one tree and one type of rock)
Here 4 different textures were used, one describing a mixed forest/rock, dense forest, sparse forest, and only rock formations.
These are the 4 textures used. The red channel describes feature height, the blue channel defines forest or rock, and the green channel is noise used for dynamic texturing. As you can imagine, many possible forest types could be created by creating simple noise based textures.
Here only two feature types are used, the Forest Color and Forest Texture images are split for the trees and rocks. Potentially many feature types, tree species, kinds of rock etc could be represented through this system. Though there are some potential problems when merging different Forest Maps for Multi texturing, as well as with transitions between types. Some solutions to these problems will be explored later.
But even so, this process can successfully implement basic mutlitextured mixed forests
