Dark Forest Tree

## Morphology

### Absence of root

The blocks below a dark forest tree are invariably dirt instead of grass, and the tree has no part of its trunk going down the earth, that is, it has no root and when the tree exists in two contour levels, and the northwestern block is on the highest of the two contour levels, then one can observe pretty clearly that the tree is on top of dirt instead of grass. If, instead, the northwestern block of the trunk is in the lower contour level then all the log blocks of the trunk that are in the lower contour level, will descend one block space more than the ones on the higher contour level.

### Trunk

The trunk is 2 by 2 blocks in girth and might bend at the top. Its height varies between 4 to 7 before reaching foliage. The trunk goes through two layers of foliage, and the last layer of the trunk is aligned with the topmost layer of the foliage. A the two or three last layers, the trunk might have a bend.

#### Bend

The trunk might have a bend at the very end such that at the top, the trunk can be inclined a few blocks. Inclined, in the sense that, a layer (voxel circle of radius 2) on top would be shifted one block towards some cardinal direction. The layers on top can either continue with the direction taken by the first inclined logs or continue upwards (suggesting this could be some line with constrained slope). The first blocks to bend are either at one block below the foliage or when the foliage begins.

### Branches

Before the game bends a dark forest tree, it creates between 1 to 9 branches around the trunk that are either adjacent or diagonal to the logs of the trunk. The branches vary in length between 1 to 4 blocks and around the topmost block, there's a voxel cone or voxel dome of base with radius 2.4 of foliage. Then the topmost part of the trunk might be bent and as a result, some of the branches might end up hanging from the part of the bend that is adjacent to the bottom of the trunk (before the bend).

### Foliage

The foliage is overwritten by the same tree's trunk and branches and the foliage has between three to four layers. For foliages of four layers, the topmost foliage is a voxel circle of radius 1 centred in a corner, the second topmost foliage is a voxel circle of radius 2.6 to 2.9 centred in a corner, the third layer of the foliage is rather strange and requires more research. Foliages of three layers are equal to foliages of four levels, they just don't have the topmost foliage (the one of radius 1).

#### Bottommost layer of foliage

The bottommost layer of the foliage is determined first, before the tree is bent by the game, by creating a square of six by six around the trunk (that is possibly a circle of slightly less than 3 radius for each log of the trunk), and around each topmost log of each branch, there is a voxel cone or voxel dome of radius 2.4. After the tree is bent, the foliage itself is shifted towards the centre of the end of the bend, and so to calculate each of the foliage dome or cones one must take the bend into account and shift each circle accordingly.

#### Third layer of foliage from top to bottom

The third layer of foliage looks like this:

If the trunk has a branch at the south-west corner, then the question mark above is a foliage block (given that hypothetically there might be a cone or perhaps a dome of foliage around each topmost log of each branch, otherwise it would just be a circle and wouldn't affect the third layer of foliage).

> Open Question: It is not clear what shape or combination of shapes the third layer of foliage is representing or if it's any shape at all.

### Tree-tree interaction

When two dark forest trees come into contact, the second tree to get drawn, has primacy over the first tree, and with its foliage, branches, (and possibly trunk and bend, though this has yet to be observed) it might overwrite parts of the other tree, such that it becomes more monstrous and unpredictable than without the interaction with the other tree. Apparently the game begins by drawing the western trees, and continues with the eastern ones, but this idea requires more evidence.

### Trees near generated structures

Apparently, near generated structures, there are trees which foliage edges are more irregular than usual.
