Early in Vizerra’s development, 3DreamTeam recognized the need to have skies to match the photorealism of the virtual landmarks they were creating. They partnered with Sundog Software, makers of the SilverLining™ sky, cloud, and weather rendering engine, to create virtual skies to match Vizerra’s scenes. SilverLining had met the needs of many games and visual simulation applications in the past, but Vizerra demanded a whole new level of realism. Over a period of several months, 3DreamTeam and Sundog Software worked closely to refine SilverLining and its integration into Vizerra. The end result was both Vizerra and SilverLining becoming much better products as a result of this very fruitful collaboration.
