3D Gis Data Model Using Open Source Software
ISPRS Archive Vol. XXXVIII, Part 4-8-2-W9, "Core Spatial Databases - Updating, Maintenance and Services – from Theory to Practice", Haifa, Israel, 2010 3D GIS DATA MODEL USING OPEN SOURCE SOFTWARE A. Scianna, A. Ammoscato CNR-ICAR, Viale delle Scienze edificio 11, 90128 Palermo, Italy – [email protected],[email protected] Commission IV, ICWG IV/8 KEY WORDS: Cartography, GIS, Technology, Interoperability, Spatial, Global-Environmental-Databases ABSTRACT: Today many kinds of applications requires data containing actual three-dimensional data; fields like urban and town planning and pollution studies need 3D data, both for visualization purpose, as well as carry out many spatial analysis. This research -Management and use of distributed 3D data by open source Web-GIS software - is part of the Italian "PRIN 2007"* research project, aimed to build urban and suburban 3D models, and to interact with them using open source software only. Particularly free and open source software, used for the experimentation here shown, are Blender and PostGIS; the first one has been used to build and structure three-dimensional data, the second one for data allocation. These software interact using scripts, written in Python language. Buildings have been modeled upon the GIANT3D model (Geographical Interoperable Advanced Numerical Topological 3- Dimensional Model) developed in the research "PRIN 2004", regarding "Evolved structure of numerical cartography for Gis and Web-GIS". Python scripts, activated by Blender, allow to allocate data into a spatial database implemented through PostgreSQL and PostGis, that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, are so transferred in PostGIS. -

GETTING STARTED PHOTO REALISTIC RENDERS OF YOUR 3D MODELS Available for Ver. 1.01 © Kerkythea 2008 Echo Date: April 24th, 2008 GETTING STARTED Page 1 of 41 Written by: The KT Team GETTING STARTED Preface: Kerkythea is a standalone render engine, using physically accurate materials and lights, aiming for the best quality rendering in the most efficient timeframe. The target of Kerkythea is to simplify the task of quality rendering by providing the necessary tools to automate scene setup, such as staging using the GL real-time viewer, material editor, general/render settings, editors, etc., under a common interface. Reaching now the 4th year of development and gaining popularity, I want to believe that KT can now be considered among the top freeware/open source render engines and can be used for both academic and commercial purposes. In the beginning of 2008, we have a strong and rapidly growing community and a website that is more "alive" than ever! KT2008 Echo is very powerful release with a lot of improvements. Kerkythea has grown constantly over the last year, growing into a standard rendering application among architectural studios and extensively used within educational institutes. Of course there are a lot of things that can be added and improved. But we are really proud of reaching a high quality and stable application that is more than usable for commercial purposes with an amazing zero cost!

Tutkimusprojektit kasvavat jatkuvasti, mikä aiheuttaa tarpeen suuremmalle tietokoneteholle ja lisää kustannuksia. Ratkaisuksi tähän ongelmaan tiedemiehet ovat kehittäneet hajautetun laskennan järjestelmiä, joiden tarkoituksena on tarjota vaihtoehto kalliille supertietokoneille. Näiden järjestelmien toiminta perustuu yhteisön lahjoittamaan tietokonetehoon. Open Rendering Environment on Laurea-ammattikorkeakoulun aloittama projekti, jonka tärkein tuotos on yhteisöllinen renderöintipalvelu Renderfarm.fi. Palvelu hyödyntää hajautettua laskentaa nopeuttamaan 3D-animaatioiden renderöintiä. Tämä tarjoaa uusia mahdollisuuksia mallintajille ja animaatioelokuvien tekijöille joilta tavallisesti kuluu paljon aikaa ja tietokoneresursseja töidensä valmiiksi saattamiseksi. Renderfarm.fi-palvelu perustuu BOINC-pohjaiseen -

Hi, My Name Is Thomas Ludwig, I'm with Glare Technologies
Hi, my name is Thomas Ludwig, I’m with Glare Technologies, developers of Indigo Renderer We’re a small company of 3 fulltime employees, plus some friends and contractors helping out. I’ve been with Glare for 10 years now, though the history of Indigo stretches back further than that as a hobby project of Nicholas Chapman. 1 I’ll start with a brief history of Indigo Renderer and our market context, and then go over some motivating examples for some of the design decisions. Difficult indirect lighting, especially caustics, is not a focus of most rendering systems so I’ll go into detail about that, followed by user and developer perspectives for using bidirectional algorithms. 2 Basis is of course Veach’s thesis, and Maxwell early pioneers in physically-based MC Non-CG specialists e.g. architects, CAD designers, people with primary job in design, want good results easily SketchUp and Revit users for archviz, C4D for productviz, Blender CAD 3 Indigo Renderer places great emphasis on image quality, and simplicity. 4 Biggest enabling assumption of viz: scenes can fit in memory Relaxing this constraint allows powerful bidirectional methods Pronounced advantage over unidir for rendering caustics Fast early convergence big practical benefit of MLT, useful for previews 5 For unidir to sample localised reflections, needs path guiding methods When there is realistically modelled glass in front of emitter, you need bidir methods 6 Scenes as complex as this are not the norm, but same high accuracy engine rendering any archviz or productviz scene 7 Many -

Appendix a Basic Mathematics for 3D Computer Graphics
Appendix A Basic Mathematics for 3D Computer Graphics A.1 Vector Operations (),, A vector v is a represented as v1 v2 v3 , which has a length and direction. The location of a vector is actually undefined. We can consider it is parallel to the line (),, (),, from origin to a 3D point v. If we use two points A1 A2 A3 and B1 B2 B3 to (),, represent a vector AB, then AB = B1 – A1 B2 – A2 B3 – A3 , which is again parallel (),, to the line from origin to B1 – A1 B2 – A2 B3 – A3 . We can consider a vector as a ray from a starting point to an end point. However, the two points really specify a length and a direction. This vector is equivalent to any other vectors with the same length and direction. A.1.1 The Length and Direction The length of v is a scalar value as follows: 2 2 2 v = v1 ++v2 v3 . (EQ 1) 378 Appendix A The direction of the vector, which can be represented with a unit vector with length equal to one, is: ⎛⎞v1 v2 v3 normalize()v = ⎜⎟--------,,-------- -------- . (EQ 2) ⎝⎠v1 v2 v3 That is, when we normalize a vector, we find its corresponding unit vector. If we consider the vector as a point, then the vector direction is from the origin to that point. A.1.2 Addition and Subtraction (),, (),, If we have two points A1 A2 A3 and B1 B2 B3 to represent two vectors A and B, then you can consider they are vectors from the origin to the points.
