Overview

Biosphere3D is an open source project that targets interactive landscape scenery rendering based on a virtual globe. The software system supports multiple scales but focuses primarily on the creation of realistic views from eye-level (First Person View) or near ground level. The software is released under the MPL license and developed by Lenné3D for use on personal computers.

Biosphere3D was released for the first time in 2007 by Dept of Visualization and Data Analysis at Zuse Institute Berlin. Applications are in Landscape planning, Landscape architecture, visual impact assessment, e.g. of Wind farms, Power stations, Land use planning, Archaeology, Urban planning, and forestry enabling to wander through landscape scenarios or virtually reconstructed historical landscape and gardens. Biosphere3D, initially funded by the Federal Ministry of Education and Research (Germany) within the R&D project ‘SILVISIO‘, has been designed as a pure landscape visualization system. Modeling of landscape features occurs in external applications such as Geographic information systems (GIS), simulation models with GIS data output, and 3D CAD tools such as Google SketchUp. Users can interact with the globe by rotating it, tilting the view, and zooming in and out. 3D scenes are composed based on the import of digital elevation model (DEM) data, image raster files, ESRI shapefiles, Collada and kml/kmz files, e.g. from SketchUp or Google 3D Warehouse. Three-dimensional plant models can be loaded with distribution maps (Point or MultiPoint Shapefiles or OIX plant distribution files) and positioned on the terrain model. Building blocks can be generated from footprints based on Polygon Shapefiles. The height of the blocks can be interactively edited per Layer in the Object Layer parameters.

Any raster file format is supported, which can be read by the open source library GDAL but Geodata must be in geographic coordinates and WGS 84. The data structures used by Biosphere3D require no or short pre-processing steps; so all data can be modified on the fly with minimal turn around times. This facilitates quick 3D scene generation and a semi-interactive workflow. Biosphere3D exports Portable Network Graphics (PNG) and in the high dynamic range imaging image file format OpenEXR in virtual resolutions as stills and animations. Other features of Biosphere3D include support for advanced visual effects such as physics-based atmospheric scattering, Screen Space Ambient Occlusion, sun shading, and water shading.

Computer Requirements

Hardware requirements:

• a standard 64bit dual core PC, 2 GB RAM and a GPU supporting OpenGL 4.0
• depending on project size more RAM and a current CPU is recommended

Software requirements:

• we are releasing 64bit Windows versions only for now, other operating systems may follow in the future
