Screen Space Ambient Occlusion
Malte Clasen has ported parts of the NVIDIA Direct3D 10 sample code to support Screen Space Ambient Occlusion.
Biosphere3D now also supports optional 16 bit Floats for Deferred Shading (turn on in Preferences) on recent GPUs (tested on Radeon HD4850), which e.g. results in better water shading (also due to implementation of Schlick’s approximation of the Fresnel equations).
This Biosphere3D.org Blog is now the official news site, while other information on Biosphere3D including download links has moved to our Wiki at Sourceforge. There are new Installer versions (x86 and x64) with new features such as Auto-Update and a Scenario Manager to store and switch between scenarios and blend between/ compare two, e.g. before and after.
Note that users, who are not developers, should either switch to the installer versions or change the SVN URL, if you want to be able to downgrade via SVN.

Biosphere3D now supports anaglyph rendering with 2 color glasses (red and cyan recommended). This stereoscopic 3D technique has been always good for funny pictures.

Biosphere3D with new compass feature and NASA Blue Marble Next Generation w/ Topography and Bathymetry
Thanks to Steffen Ernst, Biosphere3D got intuitive mouse, keyboard, interactive compass, and even 3D space mouse* navigation support. It is still not perfect but makes a lot more fun and now it is less possible to get lost. We have added a Blue Marble Next Generation raster file w/ Topography and Bathymetry (Source: (world.topo.bathy.200407) in 2km/pixel resolution to the start screen.
* SpaceNavigator™ - make sure that you have the Windows driver from 3Dconnexion installed.
We’ve published a new application paper:
Paar, P., Appleton, K., Clasen, M., Gensel, M., Jude, S. & Lovett, A. (2008): Interactive Visual Simulation of Coastal Landscape Change. -In: Ehlers, M., Behnke, K., Gerstengarbe, F.-W., Hillen, F., Koppers, L., Stroink, L. & Wächter, J. (eds.), Digital Earth Summit on Geoinformatics 2008: Tools for Global Change Research, Wichmann, Heidelberg: 153-159.
Abstract
This paper describes and evaluates the application of the interactive landscape visualisation system Biosphere3D in a case study of cliff erosion in Norfolk, on the eastern coast of England. The study builds upon previous work on coastal zone management by the Tyndall Centre for Climate Change Research at the University of East Anglia. Biosphere3D is an open-source system, which supports multiple scales on a virtual globe, loads GIS data at runtime, and focuses on real-time rendering of vegetation and foreground detail.
The 3D landscape model has been developed by using scientific modelling data on cliff retreat to define changes in digital elevation models and then incorporating other spatially referenced content to represent natural and man-made features. We compare the use of Biosphere 3D with previously-employed visualisation techniques and discuss the requirements of digital globes to support more convincing depiction of local visual landscape impacts of global change.

The Free Software Foundation considers a “Google Earth replacement” to be a high priority project. We welcome anyone helping on Biosphere3D to build a free alternative. This can happen in many ways, for example by adding web data sources, e.g. the OpenStreetMap Project, by improving the user interface, or by writing tutorials.
From now on, this will be the main platform for information about the Biosphere3D landscape visualization system.
