Tree lines
They represent the age of the tree and may be more or less distorted depending on the tree. Lines can vary in color and opacity. Some lines have a chance to be rendered with dots.
§ 03 — About the piece
How it's made.
It is built around 3 elements that mimic real tree features.
Knots
They are points of disruption present along some of the lines. They push and pull the tree line around them and provide more movement to the piece.
Bark
It's a frame of thousands of little circles that coats the outside of a piece and provides a different texture and contrast with the smooth lines.
