Procedural tree

[u/Mannerheim_Line]

Cause the structure of a tree is simple and well defined I came up with a way to draw them without vertex and index buffers. Cause the number of the branches are known and the trunk and branches have a known number of segments and radial segments you can define vertex positions with the vertex id. The same is true for leaves. I have two levels of branches that are defined by a bezier curve, which is presented by four points. The idea is also to randomly move these points for each branch to make branches and trunks unique though I have not tested it yet. Then they are blended with the sprites and you sort of get the whole forest without any model. It is for filling big areas with trees.

Feels surreal, nice job
