![]() This approach could simplify drawing the branch and reduce mathematical calculations, but I thought that would consume a lot of memory stack. Usually in Processing you can recursively call pushMatrix() to shift the origin and angle of the current coordinate. I then randomly create 2 or 3 branches in each recursive call the thickness also decreases with each call. In the very first version, I just draw white trunks on a black background using the line() funtion in Processing. In this article I will show some diagrams and code snippets to explain how this work has gradually developed from the original version to the final pencil-sketch like drawing. The only drawing tools I used are point(), ellipse(), line(), and simple mathematical calculations which are very basic features in Processing or in other programming-based drawing tools. You might guess that I probably used 3D drawing, lighting effects, texture mapping, and other complicated tricks to create this work, but in fact I didn't use any of these things this work is a pure 2D drawing, and does not use any bitmap material. ![]() until the result looked like a real pencil sketch. Then I gradually added improvements in several stages: gradual thickness, randomly twisted branches, shades of light, bark texture, etc. It started with the "recursive function." The first version was just a tree made up of a bunch of straight lines. ![]() The forest that I have drawn is no exception. ![]() All well-trained programmers will, on reflection, explain how to use a "recursive function" to draw the structure of a tree. You, as the artist, hold the power to make that happen.Drawing a tree using code is a very basic exercise in programming. Every tree is a story waiting to be told, a character waiting to be brought to life. So, take up your coloured pencils, step outside and breathe in the beauty around you. The more you observe, the more you'll see, and the richer your drawings will become. Feel the rough texture of the bark, look up and lose yourself in the labyrinth of branches, and study the dance of light and shadow on the leaves. You now have the tools to turn your observations into art, to see the individuality in each tree, their unique structures, the interplay of light and shadow, and the myriad colours and textures that make each one a masterpiece of nature.ĭon't just draw trees immerse yourself in them. By paying attention to the details and shapes in front of you - rather than relying on memory - you can create more accurate and realistic drawings.ĭrawing trees is more than a mechanical task-it's an intimate journey of observing, understanding, and translating nature's beauty onto your paper. In conclusion, drawing trees can be a fascinating and rewarding experience. These unique characteristics give each tree its own personality. Notice how some branches grow upward while others droop downward. Take a walk in a park or forest and study the way branches twist and turn, reaching towards the sky. Observing real trees can provide valuable insights into their branching patterns. Incorporate these elements into your sketch to add dimension and depth. Think about how light would naturally hit these surfaces, creating areas of highlight and shadow. The branches closest to the trunk are thicker and gradually thinner as they reach the outermost tips. When drawing branches, it's helpful to think of them as a series of tapered cylinders. As the trunk extends upward, it branches into smaller limbs and twigs. Depending on the species, it can be thick and sturdy or slender and graceful. The trunk serves as the tree's backbone, providing support and stability. By understanding the "skeleton" of a tree, you can bring your drawings to life. Remembering that each tree has its unique structure and character is important.
