This document describes the development of a visual impact evaluation system called VIESORE for assessing proposed offshore renewable energy installations. The system uses 3D modeling software to generate photorealistic visualizations of installations from different viewing points and lighting conditions. Developers have successfully imported real-world GIS data on terrain, turbine locations and viewing points into the 3D software. Current results include visualization renderings of planned offshore energy projects. Remaining work involves improving the user interface and adding reporting functionality.
