Affine Transformation A mathematical function such as a translation, rotation, scaling, or shearing that transforms a line into a line or a plane into another plane. Using a trick, such functions, which are usually difficult to combine due to the nonlinear behavior of the translation, can be implemented with just one matrix multiplication: the number […]

Modeling a Tree
in the second modeling example, a small tree is to be created. The basis for this example is a tutorial by Andreas Kathky which can be found also on the Greenworks website. The tree consists of four tree components that are linked together, and therefore has three branching levels. Here the structured creation of the […]
Modeling a Flower
Although the rendering of trees requires a relatively small number of components, experience with the system is necessary. Thus, we suggest to first model a small flower. The final result was used for the interactive rendering of plants and can be seen in Fig. A.3. The description given here refers to the Xfrog Version 3.5, […]
. Practical Plant Modeling
The web site to this book, found at “www. computerpflanzen. de” contains useful information, links to a collection of programs, and data and video sequences. Most of the content is related to our modeling system “Xfrog” which also can be downloaded there in a demo version usable with full functionality for 30 days. In the […]
SonoMorphis
SonoMorphis is an installation with genetic graphics and sound, developed by Torsten Belschner and one of the authors (Bernd Lintermann). A first version without sound was developed between 1995 and 1997[15], and extended to include sound in 1998 in co-operation with the audio designer Torsten Belschner at the ZKM Karlsruhe. The goal was to develop […]
Bill Viola, Tree of Knowledge
In this artwork, the viewer enters a 16-meter-long hallway, which measures at the entrance 90 cm wide, opens up in the last third, and then opens the view freely to a large 2.4×3.2 meter rear-projected canvas, on which the picture of a tree can be seen. As the viewer enters the hallway, the tree is […]
Collaboration with Thomas Ray
Thomas Ray’s goal is an independent evolution of computer programs with as few defaults from the outside as possible. In a technical environment, in which the only goal of programs is their own reproduction, and only limited system resources such as processor time and storage location are available, according to Ray’s view, programs will develop […]
A-Volve
In A-Volve, the viewer interacts with an unusual medium for technical installations: water. The visitor looks at a 180x 135 cm-large water basin that is, however, only filled with about some centimeters of water, and in which visual continuation is projected from the bottom. In the basin there are different organic creatures that move with […]
Interactive Plant Growing
This work originated in 1992/93 as the first joint work of the two artists. It was shown world-wide and also was part of the permanent exhibition of the ZKM Media Museum in Karlsruhe. The viewer enters a dark area of 6×7.5 meters, into which five platforms with five different plants face a 4×3 meters-large projection […]
Christa Sommerer and Laurent Mignonneau
While for Karl Sims evolutionary techniques are a means for obtaining complex, nonplannable visual results, for Christa Sommerer and Laurent Mignonneau the algorithmic creativity of evolution stands in the foreground. The variety of organisms, which nature brought about in the course of evolution, serves as an indication of the creative potential for technically realized evolutionary […]
