An increasing number of ECOTECT users are utilizing Radiance in quite complex ways as part of their preliminary design analysis. The export functions in ECOTECT support a reasonable range of Radiance's capabilities, making the generation of basic scene files and analytical images relatively simple even for novice users. However, as the aspirations of these users build, there was need for the development of a more sophisticated version of the free Radiance Control Panel that originally came with ECOTECT. This new version takes an integrated development environment (IDE) approach, linking a syntax-highlighted editor with project management, interactive help, user-defined code templates and image analysis features. It uses a series of wizards to guide users through some of the more complex analysis functions and features a range of support tools such as a preliminary visual materials editor, batch run processing and a panorama generator. It also includes an attempt at another version of winmage for Windows to make some of the image analysis functions a little more obvious to designers.
