        1. Research

          The following research publications describe technology developed primarily by Bernd Lintermann and Oliver Deussen, et al., related to developments in technology and software for creating organic structures and Ecosystems.

          Digital Design of NatureGomputer-generierte Pflanzen Our book, Digital Design of Nature: Computer Generated Plants and Organics published by Springer Verlag, covers the history of developments in this field and was released in 2005. The original German edition of the book, Computergenerierte Pflanzen: Technik und Design digitaler Pflanzenwelten, is also available.

          Current Research is primarily concerning Virtual Ecosystems, Realtime MLOD Displays of Virtual Ecosystems, Population Editing, and related themes.
