Procedural Modeling
Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and textures from sets of rules. L-Systems, fractals, and generative modeling are procedural modeling techniques since they apply algorithms for producing scenes. The set of rules may either be embedded into the algorithm, configurable by parameters, or the set of rules is separate from the evaluation engine. The output is called procedural content, which can be used in computer games, films, be uploaded to the internet, or the user may edit the content manually. Procedural models often exhibit database amplification, meaning that large scenes can be generated from a much smaller number of rules. If the employed algorithm produces the same output every time, the output need not be stored. Often, it suffices to start the algorithm with the same random seed to achieve this. Although all modeling techniques on a computer require algorithms to manage and store data at some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CityEngine
ArcGIS CityEngine is a commercial three-dimensional (3D) 3d modeling, modeling program developed by Esri R&D Center Zurich (formerly Procedural Inc.) and specialises in the generation of 3D urban environments. Using a procedural modeling approach, it supports the creation of detailed large-scale 3D city models. CityEngine works with architectural object placement and arrangement in the same manner that software like E-on Vue, VUE manages terrain, ecosystems and atmosphere mapping. Unlike the traditional 3D modeling methodology which uses Computer-aided design, Computer-Aided Design (CAD) tools and techniques, CityEngine takes a different approach to shape generation via a rule-based system. It can also use Geographic information system, Geographic Information System (GIS) datasets due to its integration with the wider Esri/ArcGIS platform. Due to this unique feature set, CityEngine has been used in academic research and built environment professions, e.g., urban planning, architec ...

Parametric Design
Parametric design is a design method where features (such as building elements and engineering components) are shaped according to algorithmic processes, in contrast to being designed directly. In this method, parameters and rules determine the relationship between design intent and design response. The term ''parametric'' refers to input parameters fed into the algorithms. While today the term refers to the use of computer algorithms in design, there are precedents in the work of architects. Antoni Gaudà used a mechanical model for architectural design (see analogical model) by attaching weights onto a system of strings to determine shapes for building features, such as arches. Parametric modeling can be divided into two main types: * Propagation-based systems, in which algorithms result in final shapes that are unknown based on initial parametric inputs. * Constraint systems, in which final constraints are set and algorithms are used to define fundamentals (structures, mat ...

Parametric Model
In statistics, a parametric model or parametric family or finite-dimensional model is a particular class of statistical models. Specifically, a parametric model is a family of probability distributions that has a finite number of parameters. Definition A statistical model is a collection of probability distributions on some sample space. We assume that the collection, , is indexed by some set . The set is called the parameter set or, more commonly, the parameter space. For each , let denote the corresponding member of the collection; so is a cumulative distribution function. Then a statistical model can be written as : \mathcal = \big\. The model is a parametric model if for some positive integer . When the model consists of absolutely continuous distributions, it is often specified in terms of corresponding probability density functions: : \mathcal = \big\. Examples * The Poisson family of distributions is parametrized by a single number : : \m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xfrog
Xfrog (X Window Finite Recursive Object Generator) is 3D computer graphics software that runs on Microsoft Windows or as a plug-in for Windows and Mac-OS versions of Autodesk Maya and Maxon Cinema 4D. Xfrog was originally developed by Oliver Deussen and Bernd Lintermann while at the University of Karlsruhe based on their research into natural systems and systematic processes found in nature. Overview Xfrog was developed to be an intuitive modeling method and GUI for creating natural branching structures based on the rules of nature. Structure and geometry is encapsulated in objects that form the description of the model. To define a model, icons (graphic representations of components) are assembled in a graph depicting the model’s structure and hierarchy, beginning with a root icon. Models are saved in the proprietary Xfrog .xfr format, a text file that contains the complete set of parametric rules for the procedural "Frog"engine to interpret and draw the polygonal model. H ...

MojoWorld Generator
MojoWorld was a commercial, fractal-based modelling program for the creation of digital landscapes, and attracted a following among artists who create space art and science fiction scenes. Originally created by Ken Musgrave, it was marketed commercially by his Pandromeda Inc. company. Functionality MojoWorld could generate entire planets through mathematics and procedural generation, using a simple graphical interface and a planet-generation Wizard. The resulting terrain could then be navigated in 3D space much like a videogame, allowing users to easily find exactly the right place for a scenic landscape picture. MojoWorld also allowed the user to edit the landscape and scene, and then have it rendered to an image by the computer.Rickets, Ed, "MojoWorld 2.0: the strangest program on the face of the planet is back, and it's better than ever", in-depth product review in ''3D World'' magazine, December 2002.
