Abstract: We present here the preliminary results of our efforts towards the de?nition of a novel paradigm for the procedural generation of pseudo-animals, using a grammar-based approach. With the term “pseudo-animal” we denote a living being characterized by a set of features mimicking the ones of real animals, but not necessarily belonging to existing species. The generation of these pseudo-animals should also plausibly re?ect the properties of the environment where the model will live.

Abstract: In this paper we propose an optimization of the Shape Diameter Function (SDF) that we call Accelerated SDF (ASDF). We discuss in detail the advantages and disadvantages of the original SDF definition, proposing theoretical and practical approaches for speedup and approximation. Using Poisson-based interpolation we compute the SDF value for a small subset of randomly distributed faces and propagate the values over the mesh. We show the results obtained with ASDF versus SDF in terms of timings and error.
