52North Triturus

README file for the 52North Triturus library

Triturus is a package of Java classes that offer basic functionality to model objects in 3-D space and to set-up simple 3-D scene descriptions.

Basic functionality:

• Basic feature geometries (3-D point sets, line-strings, elevation grids, triangulated irregular networks, etc.)
• Gridding algorithms for scattered data points
• Readers for various data formats (e.g., XYZ files and Arc/Info ASCII grids)
• Simple file exporters (e.g., ASCII files, VRML/X3D/X3DOM scene descriptions, VTK/ParaView data files)
• Generation of simple POV-Ray scene descriptions
• Cross-section generation for elevation grid models

Characteristics

• Development platform: Java version 1.6 (Windows and Linux/Unix)
• Rendering pipeline (filter, mapper, renderer) as basic conceptual reference model
• Abstraction of concrete (geo-) datasources and renderers
• Integration of basic I/O-classes and renderers (3d realtime rendering and ray tracing)
• Freely available implementation examples using this framework: [52North GeologicToolbox] (https://github.com/52North/GeologicToolbox), Web Terrain Service (OGC-WTS for LOD 0), profile service for the generation of terrain cross sections, Web application for WTS visualization using OGC-WMS as drape texture.

Development goals

The community's vision is to establish a creative surrounding, which allows efficient and sustainable development of innovative software solutions in the context of 3-D modeling and 3-D geovisualization.

Concrete development goals are:

• to provide a surrounding for 3-D geovisualization tasks, broadly usable in different fields
• to have open ended software that is easily extensible
• to be compatible to existing standards in the context of geo object modeling and computer graphics (OGC, ISO, W3C).

Installation

To compile the Triturus library, simply execute the following Maven task

'mvn clean install'

To use the Triturus library, just add the Triturus JAR file to your Java project.
