Multi-objective Numerically Coded Procedural Tree Models Reconstruction by Differential Evolution (original) (raw)

2010

This paper presents an approach for multi-objective reconstruction of procedural models for woody plants (trees). The tree model works by building the 3D structure of a tree by applying a fixed procedure on a given set of numerically coded input parameters to recursively compute building parts of a tree. The parametrized procedural model can later be used for computer animation. Reconstruction of a parametrized procedural model from the photographic images is done by differential evolution algorithm, which evolves the parametrized procedural model by fitting a set of its rendered images to a set of given photographic images. The two-objective comparisons are made on a pixel level of the images by integrating distances to nearest similar pixels. The obtained results show that the presented approach is viable for modeling of natural trees in computer animation by multi-objective evolution of the numerically coded procedural model. The use of multi-objective approach gives the decision...
