Fractals have a long history of fascinating computer and math geek alike, but this time we're going to take the way a fractal simulates natural ordered chaos and apply it to the practical purpose of drawing a natural object! However, this isn't going to be a very realistic tree, just a drawing good enough for an icon or a game sprite.
How to draw trees in Inkscape:
We'll mainly use two Inkscape tools: 'random tree' to make the trunk, and 'fractal (Koch)', used to make the foliage.
1. Effects-> Render-> 'Random tree' gives you a slightly different tree within the two parameters you specify. The 'initial size' parameter will be the overall size of the tree, and the 'minimum size' parameter will determine how many times the branches fork on average. This is easier to demonstrate than explain, so here's some typical examples:
