Artistic box trees
This short note describes a development of the traditional Pythagorean tree fractal to produce interesting three-dimensional structures based on cubes rather than squares. Adding a 90˚rotation at each bifurcation encourages three-dimensional growth, creating increasingly artistic shapes as the branching angle decreases. 1. Pythagorean box trees The Pythagorean tree is a plane fractal constructe...
متن کاملRendering Artistic and Believable Trees for Cartoon Animation
We present a novel approach to design artistic and believable trees in a cartoon-like style, which can be rendered by an animated camera to produce a convincing 3D-like experience. While computer assisted traditional animation is able to generate the desired effects, this approach still depends too much on the creation of many hand drawn images. Existing approaches fully depending on 3D geometr...
متن کاملRotated-Box Trees: A Lightweight c-Oriented Bounding-Volume Hierarchy
We introduce a new type of bounding-volume hierarchy, the c-oriented rotated-box tree, or c-rb-tree for short. A c-rb-tree uses boxes as bounding volumes, whose orientations come from a fixed set of predefined box orientations. We theoretically and experimentally compare our new c-rb-tree to two existing bounding-volumes hierarchies, namely c-dop-trees and box-trees.
متن کاملA New Algorithm for Compact Box-drawing of Trees
Several researchers has discussed the Box-drawing of trees. In this paper the more recent algorithms are investigated and a new one has been introduced, in which each cell is drawn by a square box, no two boxes overlap each other, all boxes corresponding to siblings cells of the tree have the same x-coordinate at their left and right sides, and a parent cell is drawn nearly at the middle of its...
متن کاملEvolving Phylogenetic Trees: an Alternative to Black-Box Approaches
This paper presents the main steps to reconstruct phylogenetic trees using an evolutionary algorithm with a wide range of alternative computational procedures for fitness evaluation and for tuning the search engine. Due to the fine equilibrium between exploration and exploitation of the search space, highquality reconstructions are obtained among an explosion of candidates and with the addition...
