Imagine playing a computer game in the quality seen in the movies of the 'Lord of the Rings'-series; absolute realistic lighting, details like in real life, believable skins and much more. ('Lord of the Rings'-Movie: Rendered image with ray tracing - Copyright Newline Cinema) One technique that was used creating the images for those movies is called 'ray tracing'. OpenRT OpenRT is a ray tracing library developed by the Computer Graphics Group of Saarland University. Ray tracing So, how does ray tracing work? A basic ray tracing scenario. From a virtual camera (denoted by the eye), primary rays are shot through every pixel on the screen.For every ray the intersection hitpointprimary with the object closest to the camera is calculated.

HOT Tasking Manager - HOT Tasking Manager About the Tasking Manager OSM Tasking Manager is a mapping tool designed and built for the Humanitarian OSM Team collaborative mapping. The purpose of the tool is to divide up a mapping job into smaller tasks that can be completed rapidly. It shows which areas need to be mapped and which areas need the mapping validated. Sponsorship and Funding OSM Tasking Manager was designed and built for the Humanitarian OpenStreetMap Team. With the invaluable help from: Getting Started Some resources to help you start using the Tasking Manager: Open Source OSM Tasking Manager is an open source software.Feel free to report issues and contribute. The application code is available on github. Lead developer: Pierre GIRAUD (Camptocamp) with the help of other contributors. Version
Dryad Collaborative Mapping & Crowdsourcing - Map Makerpedia Collaborative Mapping & Crowdsourcing Edit an articleby Rob Lemmens and The Google Map Makerpedia team In Short Learn the principles of collaborative mapping and crowdsourcing. Introduction Collaborative mapping and crowdsourcing are two methods of generating content on the internet, which involves contributions from a large, disparate group of individuals. There are several tools available which allow users to create and edit web content, such as tagging tools, wiki software (Wikipedia), and web-based spatial data editors (e.g., Google Earth, Google Maps, Google Map Maker, OpenLayers). Map Content on the Web A vast amount of geodata is available on the internet, through on-line maps, web services and virtual globes. Current software applications are changing the web to act more and more as platform for real-time information integration, with many web sites collaboratively controlled. © 2011 Google Different Ways of Exploiting Web 2.0 Crowdsourcing Spatial Data Infrastructure Lessons 1. 2. 3. 4.
