| Abstract in different language: | We present a new kind of parametric Lindenmayer-systems called nonlinear CSG-pL-systems, which are useful for the modeling of nonlinear fractals and fractal like objects. Nonlinear CSG-pL-systems describe cyclic CSG-Graphs, which can include several nonlinear transformations. To render the given objects a ray tracing algorithm is introduced, that is independent of the transformations and the under laying CSG-primitives. We use tapering, twist and bend as nonlinear transformations for our implementation. The new modeling possibilities and their visualization for abstract fractals and natural phenomena are investigated. |
