Modeling Trees with a Space Colonization Algorithm

چکیده
We extend the open leaf venation model by Runions et al. [RFL∗05] to three dimensions and show that it generates surprisingly realistic tree structures. Model parameters correspond to visually relevant tree characteristics identified in landscaping, offering convenient control of tree shape and structure.

THE UNIVERSITY OF CALGARY Modeling Biological Patterns using the Space Colonization Algorithm by Adam Runions A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE
This thesis introduces a class of algorithms for modeling biological patterns with branching (tree-like) and network (with loops) topologies. The key idea behind these algorithms is the marking and subsequent colonization of empty space. Models are formulated in terms of iterative geometric operations on sets of points representing the elements of the pattern and markers of free space. This con...
متن کاملSimulating crowds based on a space colonization algorithm
This paper presents a method for crowd simulation based on a biologically-motivated space colonization algorithm. This algorithm was originally introduced to model leaf venation patterns and the branching architecture of trees. It operates by simulating the competition for space between growing veins or branches. Adapted to crowd modeling, the space colonization algorithm focuses on the competi...
متن کاملSpatial-Temporal Modeling of Forest Gaps Generated by Colonization from Below- and Above-ground Bark Beetle Species
Studies of forest declines are important, because they both reduce timber production and affect successional trajectories of landscapes and ecosystems. Of particular interest is the decline of red pines which is characterized by expanding areas of dead and chlorotic trees in plantations throughout the Great Lakes Region. Here we examine the impact of two bark beetle groups, namely red turpentin...
متن کاملEfficiency of Elite Fungicide for Control of Pistachio Gummosis
Several species of Phytophthora cause crown and root rot diseases of herbaceous and woody plants. Crown and root rot of pistachio trees cause significant damages in infected orchards. The effect of foliar application with Elite (fosetyl-Al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. The frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...
