The attributes defining the look of the virtual world such as the Climate could be easily changed over simple sliders? High level parameters intelligently affect every detail. If you decide the climate should be very cold, Desaia will put snow everywhere, making it unnecessary to change textures manually.
Trees and other objects in a virtual world were actually smart and basically “knew” where they could or should stand? With semantics we make that possible. Now not only a realistic, fully automated generation is possible, but also manual changes can be made without effort because the smart sourroundings will always adapt automatically – thanks to them „recognizing“ the changes.
The implication of a certain level of coincidence would affect all automatic operations? This would mean, that even without changing any parameters or making manual changes, hitting the Generate-button twice would emit two sufficiently different worlds. Therefore designers can get countless inspirations without coming up with their own concept each time.
