GRAPHICS APPLICATIONS OF EMERGENT BEHAVIOR OF NATURE-INSPIRED MODELS

Bushra Ferdousi (18359268) 12 April 2024 (has links)
<p dir="ltr">Nature-inspired models are an exciting and innovative area of research that explores the patterns and behaviors found in organic systems. These models demonstrate emergent behaviors that result in naturalistic patterns similar to those found in nature, making them widely applicable in various graphics applications and visualization techniques.</p><p dir="ltr">In the literature review, the behavior and structure of each nature-inspired model applied in computational art, graphics techniques, and visualization are described in detail. The taxonomy developed through the analysis of the similarities and differences among these models guides the research approach towards two specific nature-inspired models: Physarum and Differential Growth.</p><p><br></p><p dir="ltr">The Physarum model is implemented based on particle systems in graphics applications, which allows for the emergence of unique behaviors. These behaviors are similar to those found in social conflict behavior observed in artificial life systems. An extension of the Physarum model with Reaction-Diffusion texture generation produces patterns similar to those found in structures such as seashells and angelfish.</p><p dir="ltr">Differential growth is simulated in a particle system coupled with a vector field, creating an interactive software for pattern formation. This software enables users to adjust the parameters of the vector field and differential growth to create patterns observed in organic systems, such as kale leaves. The research aims to determine whether this software is understandable and usable for users to create patterns effectively.</p><p dir="ltr">The taxonomy developed in this study is a valuable resource for researchers, computational artists, and programmers to experiment with nature-inspired models governing complex rules and pattern formation. These models can be applied in graphics techniques such as animation, texture mapping, and artistic designs for exploration purposes.</p><p dir="ltr">In conclusion, nature-inspired models have proven to be an innovative and effective way to create naturalistic patterns in various graphics applications and visualization techniques. The research conducted in this study provides valuable insights into the behavior and structure of these models and how they can be developed further to create new and exciting designs.<br></p>

Information feedback to local communities of HDSS sites using infographics: the case of niakhar HDSS site

Dione, Djibril January 2017 (has links)
A research report submitted to the Faculty of Health Science in partial fulfillment of the requirements for the degree of Master of Science (MSc) in Epidemiology - Research Data Management June 2017 / Health and Demographic Surveillance System (HDSS) sites are institutions that primarily collect periodic demographic and health related data within a defined geographical area. The data are then analysed and the research findings are published in peer-reviewed journals or presented at conferences and workshops. However, In some sites there are processes for disseminating the research findings to the participating communities. The dissemination of research findings using infographics can enable health care service providers and community decision makers to make effective use and incorporate such findings into their strategies, policies and planning to improve heath outcome of the population. In this project, we have implemented a visualization web platform that can be used by researchers, community decision makers and public health policy-makers to better identify trends associated with the research findings. We implemented this platform on top of the core HDSS dataset. An Extract Transform and Load (ETL) process feeds processed data to our layer which then provides the requisite utility tools for visualization. We have provided a framework that allows other cohort studies that utilize the HDSS core dataset as baseline data to be plugged in for additional infographics displays. We tested and prototyped our tool using Niakhar HDSS Site core HDSS datasets. The project also provides some generic guidelines that allow this tool to be used in other HDSS sites. / MT2017

Reversible deformation for computer graphics

Mason, David, n/a January 2006 (has links)
Since the introduction of Free Form Deformation (FFD) by Sederberg and Parry in 1986, a great deal of research has been performed in the area of space deformation for 3D shape modelling. However, many techniques do not provide local control, and almost all are non-unique mappings that are capable of producing foldover, making them unsuitable for use with implicit surfaces, or any object that should not self-intersect, and causing some problems for ray tracing. In this thesis, a new approach to deformation is presented. Blendeforming (Blended Deforming) provides foldover-free deformation with local control, which preserves implicit functions. Blendeformers are reversible deformations that are suitable for use in interactive modelling, ray tracing and image warping.
