The rapid development of computer graphics and three-dimensional (shorter 3D) modelling started in the 1960s. Today, the advancement of technology and, with it, graphics makes it harder and harder to distinguish between reality and computer generated imagery. Through this improvement, the use of CGI and 3D modelling has skyrocketed and is now used in a variety of different industries, such as medicine and science in general, art, film, advertisement, architecture, design and other areas.
One of the more complex parts of computer-generated imagery is still nature and the natural world. As it is much harder to mimic and create virtual organic shapes that resemble what we see when we look outside. Research and implementation of algorithms creating fractals and programs with already made models, which can be adjust based on preferences, greatly improving and speeding up the creation and rendering of nature.
The goal of this thesis, 3D modelling and tree visualisation, has been into two parts, theoretical and experimental. The theoretical part presents the history of computer graphics, its use today and the pipeline used in 3D creation. The experimental part describes the process, modelling, sculpting, texturing, lighting and lastly, the rendering of the final images. Visualisation of the model is also the main objective of the thesis and the finished product.
The main goal of the thesis was the creation of a realistic model of a tree based on an actual tree, which was used as a reference. Through creating the 3D model, we described the steps that needed to be taken to get to the final product and the obstacles we came across and how we managed to overcome them and find solutions to our problems.
