Title: Do self-organized patterns provide a solid basis for building infinite natural landscapes?

Abstract: Natural landscapes, when unaffected by human interference, are often characterized by a bewildering array of repeating natural patterns. Even in landscapes that are as good as flat, as are many dutch ecosystems, regular spatial patterns are found at many scales because of the interactions of organisms with physical forces, a process called spatial self-organization. In this talk, I will discuss how, by combining patterns at multiple spatial scales and including a multitude of processes, we can create visualisations of natural systems that are – in theory – infinite in size, without resorting to noise as the predominant factor creating heterogeneity spatial patterns occurring in the landscape, the ground and in the natural community (i.e. vegetation), we can build CGI representations that are theoretically infinite in scale. I will describe the origin of the patterns, and demonstrate how to build a visualization using patterns at different scales, using intertidal ecosystems as an example.
