This was how you became knowledgeable about light and lighting,” Flood says. “There are definitely many occasions when I get concerned, particularly when I see young lighting designers who are highly computer savvy and who are completely dependent on lighting software to do lighting design, even for relatively simple projects.” Lighting simulation software doesn’t generally offer equivalent rendering capabilities to those of architectural visualisation programs such as Autodesk’s 3DStudio Max, although Ashdown believes this is mostly intentional. While some architectural visualisation programs offer basic lighting calculation features, they do not offer the capabilities that most lighting designers need. More importantly, perhaps, the wealth of features available to digital artists in these programs makes it difficult for lighting designers to use them effectively. By comparison, lighting simulation programs are designed expressly for lighting designers, with careful attention paid to their workflow and needs. “The focus of architectural visualisation software has always been – and rightly so – on the renderings,” says Ashdown. “While these programs may use the same underlying ‘global illumination’ algorithms as lighting simulation software to simulate the flow of light, there has never been a need for, or focus on, guaranteed photometric accuracy.” The development of lighting simulation software is, and likely always will be, a work in progress. The pace of development in lighting standards from the IESNA, CIE and other standards associations has quickened in recent years with a focus on solid state lighting (SSL), daylighting, and networked lighting controls. The SSL industry in particular has exploded over the last few years, a development that has not been without teething problems. Manufacturers have flooded the market to cash in on the technology, which is lauded by clients for its potential for energy savings. Even lighting designers, many of whom remained cautious in the early days of the LED revolution, now acknowledge that Showing Bloom Unit’s unique capabilities with landscape elements, in both day and night-time conditions.
